billw: that's very interesting and has been my experience as well. I've got some 15 mauka seedlings, germination rate was very high and almost all seeds germinated around the same time. My seedlings are growing much more rapidly than any of the cuttings I took, though the seeds came from a different variety than the one I've been taking cuttings from. Given that, I agree it doesn't seem at all unlikely that mauka was actually grown from seed. I really need to find a way to induce flowering this year.

Finally! My last Yacon to sprout I spotted just barely poking out of the dirt yesterday afternoon! :3

Didn't know you were in New Zealand; that explains a lot, including the lizard-tongue.

Yeah, there are a lot of aphids on my mauka. It grows so fast that the aphids don't seem too troublesome though. I just spray it with water to wash most of the aphids off.
Lovely oca flowers. The only common heirloom that I have seen with the combination of red pedicels and green peduncle is Bolivian Red, but the stem coloration doesn't match yours, so it is probably uncommon among extra-Andean ocas. Did you observe the flower morph? Do you have a picture of the tubers?
That mashua is going to get a lot bigger.

If you got it from me, that was one heck of a slow yacon, Tiirsys!

Yeah I seem to have significantly underestimated the space that mashua needs... I'll see if I can get some more pictures this weekend. I didn't take one of the tuber, but from what I remember it looked very much like this NZ heirloom that Frank posted a picture of (the one in the middle):  |

Wow. That picture is so depressing to me; so far I've gotten tubers thumbnail-sized on down. Whine, snivel!

Did you observe the flower morph? Note that I've never seen an oca flower before, so I might be very off... but I compared it to the picture on your website and it appears to be short-styled. Also found two other varieties flowering which seem to be mid- and long-styled. I tried to pollinate them, I guess that will tell me how much I've understood of this. |

That middle one i have here (NZ), its a reliable tuber but for some reason the last two years they haven't grown as big as what yours are in the photo but from what I remember it looked very much like this NZ heirloom that Frank posted a picture of (the one in the middle): |

I might have found a match for your oca, matuyama. It didn't come to mind because I haven't been growing it very long. BK08516.7: A Peruvian variety with short-styled flower, red pedicel and sepals, green peduncle, yellow tuber with red eyes. Stem characteristics are also a match for your photo. www.cultivariable.com/wiki/index.php/BK08516.7 |

billw: That might very well be it, I'm very impressed you managed to track it down, that's some inventory you've got. Do you have anything in your notes on its yield? The scale in that picture on the wiki page says 585?

The scale in the images registers grams. The picture always represents the best single plant yield of the year the picture was taken. So, that variety is pretty average - about 500 grams is typical for heirloom varieties in my climate.

I walked past this yacon for more than a month before I noticed anything unusual.  |

I walked past this yacon for more than a month before I noticed anything unusual. Leaves of three, let them . . . . Well, that is really neat, billw ! |
