A leguminous verdict

Wolverines's orca bean
Summer's over, though it took a while before I could say that with some confidence this year. 26 degrees Celsius in the middle of September is certainly out of the ordinary for this part of the world... If it wouldn't be an indication of a rather ominous trend, I wouldn't have minded so much. As it stands, I can't help but think that I'd rather have my sweet potatoes adapt to the Scanian climate than the other way around.

 In any case, it's time for some harvest updates. I'll start with the legumes, since these are all in, fully dried, shelled, sorted and weighed. As you might remember, I had a few different legumes on the trial table this year: favas beans, peas, beans, lentils, chickpeas and some lupines. As in any good story, this turned out to be a tale of heroic successes (well, kind of), epic failures, and everything in between.

Chickpea pods
Chickpea flower
If we start with the epic failures: I've discovered that something or someone inhabiting my allotment likes chickpeas at least as much as I do. My chickpea plants did fabulous in the beginning. They germinated without much of a problem in fairly cold soil, happily grew on during the warm spring, and were soon filled with cute-looking pods. Quite a few of these pods appeared to be empty, which I had read could be due to bad pollination (in turn due to low temperatures perhaps), but a lot of them seemed to have good-sized chickpeas in them. But then the disappearances started occuring. Somehow a lot of the pods just vanished before they fully matured. I didn't make much of it at first, as I've learned to accept that the various non-humans I share the garden with demand some form of tribute from me, but when the empty pods started piling up between the plants I realized I was dealing with more than your average chickpea thief. Soon I had no pods left. I'm absolutely clueless as to who or what the culprit is. I covered the plants with netting for a while with the idea that the finches might be to blame, but the chickpeas kept disappearing. Since even the pods at the top of the plants were stolen, it feels like it can't have been a mouse or vole either. Whoever it was ate a decent-sized hole in the pods, ate both the immature and the nearly-mature seeds, and then left the empty pods in provocative-looking little piles at the foot of the plants, as well as in the adjacent pea row... Any help with identifying the rascal responsible for this greedy injustice would be much appreciated! The result of all this is that the entire chickpea harvest this year consists of half a handful of tiny seeds. Not exactly hummus material, sadly. But don't you think that I'm giving up yet!

Chickpea massacre
This year's lentil story unfolded in rather similar ways. One way or another, the lentils pods developed and then just vanished in thin air. I didn't even bother looking for survivors, since I had already decided that lentils are a bit too finicky to work with anyway. I dug them all into the soil, may the lentil project rest in peace.

The fava beans did well and I enjoyed a decent amount of them fresh. I left plenty on the plants to dry as well, though here too I had to sacrifice some to the local fauna. The bigger problem manifested itself when I starting shelling the dried beans. The majority of the pods had been invaded by what I surmise is the broad bean weevil (Bruchus rufimanus), whose larvae eat their way into the bean and then emerge from the dried seed as an adult (and rather confused-looking) beetle. The result in my case was a majority of seed with beetles or beetle-sized holes in them... While probably still edible, they're a bit of pain to sort and clean that way. I'll probably stick to eating my fava beans fresh.

On to happier news then. Dried peas are susceptible to weevils as well (Bruchus pisorum to be precise), but luckily this species is a bit less common in these regions (for the moment) and I haven't had any problems with it in my garden the past year. The different pea varieties did very well, even though the cursed pigeons decimated everything that grew out above the trellis that I had constructed. Luckily, since the trellis was pretty high anyway, the damage was fairly limited. Some of the peas had larvae of the pea moth in them (Cydia nigricana, - one certainly learns a lot about insects and their insecty habbits as a gardener), basically a small white larva that eats its way through some of the peas and then leaves a trail of web and excrement behind. Thank you very much! Overall it wasn't too bad, I think I eventually had to throw out between 5 and 10% of the peas. What was left was the following, in brackets is the approximate (and I want to underline approximate) space I had for each variety:

- Govorov - 45g (I only had a few plants of this)
- Klosterärt - 600g (a 2 meter row)
- Biskopens gråärt - 340g (1-1.5 meter row)
- Bjurholms småärt - 840g (2 meter row)
- Gotländs blåärt - 710g (1.5-2 meter row)
- Solleröns gråärt - 300g (1 meter row)

Klosterärt
Biskopens gråärt
Bjurholms småärt
Gotländsk blåärt

That's a total 1790g seeds for some 8 meters of peas, or a space of 3 to 4 m2. I'm pretty happy with that, and I look forward to the taste test.

And then, of course, for the beans. Not many problems to report here, the beans were pretty much pest-free and due to a dry and warm late August and September they dried well on the plants. The results, again with an estimate of the growing space for each variety in brackets:

- Huttiternas soup bean: 280g (1.5m)
- Borlotti: 1500g (6.5m)
- Brightstone: 910g (2.5-3m)
- Stella/Bruna bönor: 760g (3.5m - these were supposed to be 2 distinct varieties but they are almost identical and ended up together.. woops)
- Wolverine's orca: 310g (2m)

Borlotti
Brightstone
Stella/Brown bean

Summed up, that's a grand total of 3760g of dried beans for 4 rows of 4 meters, or about 6 to 8 m2.

Lupin bean (L. albus)
The lupine, finally, is still out there braving the current autumn spell we're having. I only have a couple of plants and my objective is just to see if the seed is at all edible. No big expectations there.

The final verdict of The Great Legume Project? I'll be growing more peas and beans next year, drop the lentils and stick with fava beans as a summer crop. I'm definitely trying chickpeas again, against all ods, simply because I'm biased towards chickpeas, but I'll probably be guarding them closely. Think the batata garden, annex chickpea fortress.. something along those lines.

Mixing up the maximas

You might remember that I threw all cucurbit seed-saving advice in the wind this year in embarking on something of a C. maxima landrace adventure. I've let the bees do their pollen dance and then saved and planted whatever crosses they've come up with. Since I garden in an allotment, and some of my neighbours grow winter squash as well, there's bound to be some cross-pollination with varieties that I've not selected myself. As I'm fairly picky about my winter squash, I should confess that this instilled some doubt in me at first. If I've understood the science behind this correctly, however, cucurbits are mostly pollinated by themselves or by neighbouring plants, so most of the genetic material should in fact come from within my own winter squash patch. And anyway, it's fun to try and mess things up a bit to see what happens.


 The squash are starting to mature now, which makes this an appropriate time for a first evaluation of what the bees have been up to last year. My main selection criteria, of course, will be taste, but based on growth habbit and appearance I think I can already draw some preliminary conclusions. Without further ado, here's this year's winter squashes. Let's start with the crosses:



Both of the above are a cross of Sweet Mama (F1) and an unknown paternal line. Because of the salmon-coloured spots on the squash on the left I would speculate that there's some Galeux d'Eysines genes involved (which is a pity since I didn't think it was very good, but that's the name of the game of course). Since it's a fairly round squash however, which is unlike either Sweet Mama or Galeux d'Eysines, there might be something else going on here as well. The squash on the right looks like it might be cross with Sweet Meat (because of the colour) and/or Marina di Chioggia (because of the pronounced ribbed structure).


This is another Sweet Mama (F1) cross. I'm not sure if you can tell from the picture but this is one big squash, at least half a meter in diameter. This poses a bit of a mystery since I didn't grow anything this big last year. The only variety that comes close is Galeux d'Eysines, which can, apparently, get quite large. Now genetics isn't quite as straightforward as that; you could very well cross two medium squashes and up with a larger one, but still, there's a likelihood that this is actually a cross with something from one of my neighbours. It's also definitely more yellow/orange than the Galeux d'Eysines I grew last year, though apparently there's a bit of colour variation in the latter as well. The stripes are probably from Sweet Mama (it shows up in quite a few of the crosses, could be a dominant allele?). I'm selecting for small to medium-sized squash, and I've yet to come across an orange-skinned squash that rivals the green or blue ones in taste, so it's unlikely I'll be saving seed from this monster. It looks impressive though.


This Burgess Buttercup cross more clearly includes some Galeux d'Eysines genes. It has the stripes and shape of Burgess Buttercup, and the skin colour, size and some of the warts of Galeux d'Eysines. I hope it inherited its eating quality from its mother...


More Sweet Mama offspring. This squash has a slight teardrop-shape, which makes me suspect that it might have crossed with a hubbard squash. I only grew Blue Ballet last year, which is a scaled-down hubbard, and this is one is quite a bit larger than that, but still, that would be my best guess.

Then there's also some less exciting crosses:


This looks pretty much like a Sweet Mama squash, but it's more vining in its growth habbit and perhaps a bit more squared than your average Sweet Mama, so it might actually have crossed with Burgess Buttercup. 


A Burgess Buttercup cross that looks exactly like a Burgess Buttercup, if perhaps slightly less block-ish. It probably crossed with itself.


This is a Green Hokkaido cross. Again, I fail to see the difference with the original Green Hokkaido at this point.

Finally, I'm also growing a bunch of named varieties this year, mostly to add some more (supposedly) excellent squashes to the maxima mix, and also simply because I seem to have an unquenchable thirst for trying new winter squash varieties. I've only got one plant of each of these:


To the left is Sibley, to the right Guatemalan Blue. Both are banana-type squashes with supposedly excellent eating quality. Guatemalan Blue is significantly larger than Sibley (it's probably about 40-50 cm long), but not nearly as productive (I've counted 4 medium-sized Sibley squash on the one vine that I have, which is quite good for a Maxima squash, at least in my garden)

   

Ah, Marina di Chioggia (left), one of my absolute favourite maximas so far (taste-wise) but frustratingly late to set fruit and mature. I can't give it up though, so I'm hoping to transfer some of its genes into my proto-landrace. To the right is Bon Bon (F1), a Buttercup-type that I'm quite impressed with so far. I'm not sure if it just happened to get the best and most fertile spot in the garden, or if this is really just a superior variety, but this is one healthy-looking and vigorous plant. If I'm not mistaken I've counted 7 decent-sized fruits on this one vine, which would make it by far the most productive maxima I've grown so far.


Hokkaido, from Real Seeds. This seems like a pretty standard orange Kabocha squash, though it was probably one of the earliest to vine and set fruit. The leaves on this plant have a silvery appearance to them, which is a bit unusual.


Sweet Meat Oregon Homestead or Blue Kuri. I'm growing both, and they seem similar enough for me to have forgotten taking a picture of the other squash. At least Sweet Meat, whichever of the two it turns out to be, seems to be doing much better than last year, so hopefully I'll have the opportunity to evaluate the fully-matured squash this time.    

Crown Prince, a squash with a royal reputation.


Blue de Hongrie. Not so much Blue as white though...


Buen Gusto de Horno. I'm not terribly impressed with this one so far, though I had read a lot of good things about it. This plant isn't particularly vigorous and it has only put out one fairly small squash. The taste better be out of this world!

 

And last, and perhaps also least, Uchiki Kuri, which put out two tiny squash and then decided to just sit there and enjoy the sun. I'm not sure things will work out between us. 

So far so good, perhaps I've inherited a bit more Galeux d'Eysines genetic material than I had bargained for, but all in all there's some interesting material here to work with. Needless to say I already look forward to the taste testing. I've also become intrigued with the genetics involved in all of this, so next season I'll probably try to make some controlled crosses just to play around a bit. Sweet Mama x Marina di Chioggia seems like an obvious choice; I was already planning on doing that this year but I didn't get around to it.

Peas on my mind

Well not just peas, really, but several representatives of the Fabacaea, that is, the legume family. This year I've embarked on a small legume trial that I've somewhat bombastically titled The Great Legume Project. My aim is mostly to try some new things and have some good fun in the process, but I'm also interested in discovering which legumes I could adopt as reliable food staples, that is, for drying and using throughout the winter. Ideally of course, I would just grow all of them, all the time, and indulge in the incredible diversity that the legume family has too offer. There's probably a risk that I would do exactly that if I had hectares of land at my disposal. In the real world, however, my growing space is limited (and seems to come under increasing pressure every year), and so is my patience for plants that demand a lot of pampering without giving much in return. Selection there will be! Anyway, this post is a brief overview of the different legumes that I'm growing this year, and how they're doing so far. I already have half-developed plans for trialling mung beans and cow peas next year, so this project is unlikely to end here...

Fava beans

Ah, good old fava beans. Hardly a newcomer in the garden, but I've only ever used them in their immature form. I know you can eat the dried seeds like any other bean, but I've never done so, so I don't know if they're very good. I'm about to find out. There's five varieties currently inhabiting the fava bean patch: Aquadulce, Solberga, Express, Green Longpod and Göteryd. The favas have suffered a bit from the abundant growth in the neighbouring pea patch however, which has overshadowed them more than I had reckoned with. If you think this implies a certain bias in favour of the peas on my part, you're probably right to some extent... To be very frank, I'm mostly interested in the immature favas, which I know are great. But I promise I'll try to contain myself and give the dried seeds a chance as well.

Peas

Whereas I'm yet to fully fall for the fava, I'm already a complete pea convert. I'll have peas in all their forms and shapes, please. The fresh peas I grow never make it to the kitchen though, I usually just munch on them in the garden, if the d*mned pigeons don't get to them first, that is. This year, however, I'm particularly focused on the dry/soup peas. I'm growing six varieties: Govorov, Klosterärt, Bjurholms småärt, Sollerön gråärt, Biskopens gråärt, and Gotländsk blåärt. The Govorov and Bjurholms småärt (Swedish for 'little pea from Bjurholm) are green peas, the Klosterärt is a yellow pea, and the other three are 'grey peas', aka black or maple peas. The maple peas are supposed to make a good substitute for chickpeas, so I'm really, really (really!) curious about them, I've never tried them. Sollerön and Biskopens have pink flowers, green pods and brown/red seeds, while the Gotländsk blåärt has purple flowers, purple pods and red/brown seeds. They're very ornamental, and all seem to be extremely prolific, particularly perhaps Klosterärt and Bjurhölms småärt. Sollerön and Biskopens were the last to flower, but all are coming along nicely now. I can't wait to dig my hands into a jar of homegrown dried peas! So yes, I suppose I should admit to a certain bias towards the peas, they've already earned their permanent residence in my garden. If only I could grow a lot more of them, somehow...
A wall of peas: Klosterärt and Bjurholms småärt
Chickpeas 

The peas are vying with the chickpeas for the title of most favoured legume crop. As anyone who has grown them will have to agree, there's just something incredibly loveable about chickpea plants, with their feathery leaves, their wavy growth habbits and their cute little flowers and seed pods. So yes, these are coming back next year as well, and in fact I've already ordered a couple of heirloom varieties from the US to seriously expand my chickpea trials next year. This year I'm growing three batches: Black Sicily, a black chickpea; Golden Dragon, an orange/yellowish variety; and a blend of standard tan chickpeas from various grocery stores. I sowed all of them at the end of March, together with the peas and the fava beans. The Black Sicily and Golden Dragon were quick to emerge, but cutworms got most of the seedlings. I therefore had to resow, after which more were cut down, and in the end I was left with only 15 plants or so in total. The grocery store mix never emerged, so then, a few weeks later, I decided to sow the entire jar, which must have been several hundreds of seeds. Only two plants finally came up. I suppose this is largely due to environmental conditions. The Black Sicily and Golden Dragon apparently were selected for emergence in cooler soils, which makes them valuable in my conditions, seeing that it's unlikely I would get mature chickpeas if I would wait until the soil has warmed before sowing. The plants seem to have enjoyed the warm spring. They are growing well and are bearing an abundance of pods. I suppose I'll need to save most of the seeds for next year's expansion, but perhaps a modest homegrown hummus is within the range of possibilities. Patience, patience. 

Lentils

Lentil 'Gotlandslins',
with potato onions in between
Last year I grew 'Gotlandslins', a lentil variety that derives from Gotland, Sweden's largest island. The rabbits got most of them however, and what was left resulted in a pretty meagre yield. I wasn't all that impressed but couldn't resist sowing them again this year. This time I've managed to keep the rodents out, and the plants generally seem to be doing much better than last year. There's plenty of pods on the plant, so I might actually be able to eat some of the lentils this year. Overall, these are quite fun to grow, and they're definitely cute, but as a potential staple crop I can't help but feel that they're a bit too much bother. If only the seeds would be five times as large, and grow together in long pods. A bit like a pea, say... Now there's a plant breeding challenge.


Dry bush beans

Dry beans are perhaps the centrepiece of any legume collection, if only because of the vast variety of different colours and patterns that are out there. I had to seriously restrain myself when ordering bean seed, and even then I still ended up with an dry bean patch twice the size of any of the other legumes. I'm growing a bush variety of Borlotti beans, some store-bought Swedish 'bruna bönor' ('Brown beans'), Stella (another brown bean), Hutteriternas Soppböna (a pale, greenish, and very plump round bean that I received through Sesam, the Swedish society for the preservation of heirloom vegetable varieties), Brightstone (a brown bean with dark blue speckles) and Wolverine's Orca (a black&white bean that indeed looks a bit like an orca whale). The plants are flowering at the moment.

Lupin

And finally, a bit of a outsider: lupin beans. The species that I'm growing (L. albus) is far from appropriate as a staple food (it's supposedly quite bitter and requires extensive preparation before it's palatable), but I nevertheless look forward to trying it as a novelty food. Lupin beans, soaked for extensive periods in order to leach out the alkaloids, are a popular snack in some Mediterranean countries. Supposedly there are a number of 'sweet' lupin varieties around that have been bred for lower alkaloid content and therefore require no soaking (particularly some strains of L. angustifolius), but these seem a bit hard to get a hold of. I've yet to get my hands on them at least, but they are definitely on the wishlist. The L. albus, meanwhile, has been treated somewhat unfairly the past few months; I all but neglected it during most of the spring and early summer. Despite the lack of watering and the dry spring it has done well and is now flowering quite happily.

That's about it for the (dry) legumes this year. So far so good.

Sweet potatoes and some sweet sweet potato seed

Slips ready to be potted
Summer's here! Well, that's what it feels like at least. We've been having an unusually warm May here, with a monthly average some 3°C higher than usual and extended periods of hot and sunny weather. As a result, the garden has gone into turbo-mode and I've already managed to plant most of the sweet potatoes. Usually the beginning of June is a more reasonable time for this, though I never seem to have the patience to wait that long. Now though, some are already starting to put out new growth, so my impatience is actually paying off for once. I have a bunch of latecomers that are refusing to put out slips, but with tropical weather forecasted for the coming week, they'll catch up soon I hope. Barring some serious force majeur, that means I now have a final list of the varieties I'll be growing this year:
  1. T65 - reliable producer, does not flower.
  2. Georgia Jet - should be a reliable producer, but did badly for me last year. I obtained what I hope is a better strain, so let's see. Should flower easily.
  3. Purple - (I called this Nordic Purple before, but I'm pretty sure it's the same variety that is elsewhere known by the name Purple) - purple-fleshed variety, not very productive but flowers profusely.
  4. Bonita - only had one plant of this last year, so it's hard to say how productive it was, but it flowers.
  5. Burgundy - same as with Bonita, plus the tiny tuber I managed to overwinter is just starting to put out slips. Flowers.
  6. 'Nordic White' - unknown white-fleshed variety, fairly productive here, and flowers.
  7. 'Nordic Orange' - medium productive, but I'm not sure if it flowers. I thought I saw some flowers on it two years ago. If it doesn't flower this year, I'll drop it.
  8. Mystery - a Georgia Jet mutant, haven't grown this before, but if it's anything like Georgia Jet it should flower easily.
  9. ? - a complete mystery this one! 
  10. Bunduguza - starchy white-fleshed African variety, lowish yield, no flowers.
  11. Burundi - starchy yellow-fleshed African variety, lowish yield, no flowers. This was the best out of all the African varieties I tested last year.
Then there's two varieties from the highlands of Papua New Guinea, a region that apparently can get quite chilly at night (relatively speaking of course, it's still a tropical area), and so should theoretically be somewhat cold-adapted. There's some hope, therefore, that compared to your average I. batatas variety, these two will feel a bit more at home here in maritime Malmö. They will join the others in the garden, provided they put out some slips soon. Both have roots, and one has a tiny slip forming, but I sure wished they'd hurry up a bit:
  1. Kainantu 
  2. Aiyura
I. batatas seed sprouting
And then, just as I thought I would get away with growing just 11+2? varieties this year, I received a small package with seeds. That is, proper sweet potato seeds, that rarest of things! These too are from the Papua New Guinean highlands. In practice, I suppose the chances are fairly slim that anything useful will come out of them. I generally put more faith in efforts to produce seeds under northern growing conditions, as Telsing Andrews has succesfully done last year, and as I hope to achieve myself this year. Nevertheless, a tiny chance is still a chance worth pursuing, plus it will be loads of fun to play around with these seeds. I promptly scarified some of the seeds with sandpaper, soaked them for half a day, and sprouted them. Germination rate was higher than I had anticipated, of the 35 seeds I soaked, 29 sprouted. That's 29 new sweet potato varieties, right there. Quite a bit of difference showed up in the phenotypes, with some seedlings showing intense red leaf colouring, some being completely green, and some lying somewhere inbetween. True leafs are deltoid or cordate, with a few of the seedlings having toothed edges.
About half of the seedlings
The batata battle plan for 2016 then: 1) Grow everything under a floating row cover for as long as practically possible, in order to speed up flowering. I've given this some thought and I didn't want to go the plastic mulching route just yet, I'd prefer to get seeds without too much 'cheating' technologies. Call me a botanical luddite! 2) Evaluate varieties for flowering onset, potential seed-set, and yield. 3) Share flowering varieties with collaborators in order to increase the chances of seedset under nordish conditions. 4) Acquire more flowering varieties. 5) Repeat.

 As simple as that!

Bloom for me, mirabilis expansa

Mauka seedling, Spring 2015
I realize that a status report on last year's mauka cultivation is long overdue. I was holding off this post hoping that I would be able to invoke your envy with some pictures of my magnificently flowering mauka, but alas, the Inca gods refused to bestow this pleasure upon me. It might very well be that I angered them somehow. As you will remember, mauka combines the unfortunate characteristics of being frost-tender and flowering under short-daylength conditions, right in the middle of the European winter. I therefore brought in two mauka plants (one Roja [that I had mistakenly labelled CIP208001 before] and one Blanco) in November with the intention to induce flowering and produce seeds. Let me clarify that I don't possess the best of conditions for overwintering plants indoors. I live in an appartment that gets quite dry in winter and the only outdoor space I possess is a 2sqm balcony (that I manage to cram full of plant starts in spring). Greenhouses, spare rooms, cold banks and root cellars are utopian concepts to me. If anyone would like to make me a present of, say, a farm, that would be very much appreciated...

Mauka root close-up, with wireworm damage
Anyhow, the maukas got a rough ride through the winter. Shortly after I brought them in, both plants got infested by aphids, which in a warm, dry and predator-free environment is prone to spiral out of control pretty quickly. Since we don't usually get frosts that often here in November and December, I figured I could more or less control the aphids by keeping the plants out on the balcony as long as possible, and just transporting them inside whenever a frost threatened. This worked pretty well for a while, but then one day in December (I guess you see where this is going..) we had a rather violent storm that pretty much blew the foliage to pieces, leaving behind a sorry-looking, bony mauka skeleton. The plants were undeterred however and quickly sprouted new leaves indoors. Then I was travelling over Christmas and New Year's, and upon my return I discovered that my absentee watering regime had failed me. Again, both mauka's lost their entire foliage, but they weren't dead and again resprouted leaves, although much less decisively than the first time. A plant that takes this much abuse definitely has my respect, though I would rather have avoided it.

But then there they sat, during January, February, and March, with no signs at all of flower buds appearing. Frustrating. I dutifully ferried them between the balcony and the living room, gave them all the love and attention I had to give (well kind of, anyway... the Roja plant eventually died somewhere towards spring, I'm not sure why...) but apparently it just wasn't enough for Pachamama and colleagues. The mauka flowering code remains uncracked, for me at least. I've now planted the Blanco in the garden together with its siblings. I might give it another shot next year, or else I'll try to lure a helpful greenhouse owner into adopting a mauka plant or two for the winter. Any volunteers?

Mauka Blanco
Mauka Roja, 2nd year growth
Seeds are not everything of course (though I have to confess I think increasingly more of them). What my plants did produce last year was plenty of roots! Of the nine Blanco seedlings that I harvested (I left a couple in the garden to see if I could overwinter the roots in situ - the answer is no), all but one were significantly larger than the first-year roots I had harvested from my two Roja plants the year before (both of which were a meagre 150 grams). Root weight ranged from 120g to 700g, with 3 roots weighing 500g or more. I also had three Roja plants (two plants in their second year, and one cutting) that were 1kg, 1,1kg, and 30g. All in all a pretty good result, which somehow confirms my hunch that the Blanco variety is superior to the Roja in terms of yield. Observation also leads me to believe that the Roja is marginally more susceptible to (light) frosts than Blanco, though the difference is probably a matter of decimals. They will definitely need more than that if they are to stand their own against the Swedish winter.

There's plenty of roads still to be travelled for mauka and me in 2016 and beyond. Apart from seducing it to bloom sooner or later, I would also like to get my hands on the CIP208001 variety, which looks a lot like the Roja but should have much better yields. And then of course, it would be exciting to try and find some additional varieties. After all, who knows what unexplored gems are still hiding somewhere in mauka's Andean homelands...
