Harvest, Oca & Crosnes

oldherb(z8 Oregon)December 7, 2004

The harvest of my Oca and crosnes was delayed a bit due to hernia surgery...I had three of them that needed repaired and figure I got them from digging all the boulders out of my veggie garden, but that was 2 weeks ago. At any rate I have decided the crosnes (Staychys affinis (S. seiboldii) are not really worth the trouble and a pain to sift out of the soil...I grew them in a whiskey barrel and spent about 3 hours sifting through the soil (I had to take my time due to I'm still healing)...Hope I got them all but I guess I won't know now until next year. From one plant I harvested about 2 cups of pure white bulbs that are not very flavorful but nice and crunchy. They would make interesting food to feed to the unsuspecting guest as they often look like insects...think white scorpion nymphs. I have a better opinion about the oca.

It was my first time growing oca(Oxalis tuberosa)and I love it! The tops are good in salads and the tubers are the most wonderful rose-red to creamy white color making them like jewels in the soil. Some were the size of small marbles and others were the size of baby spuds. Now to dry them and see what we end up with flavor-wise. I understand if they are sun-dried it reduces the oxalic acid in the tuber making them sweeter and better to stomach. I'm off to do more research on them...If any of you are experienced with Oca please E-mail me. I want get better at growing them. I ended up with only about 1.5 lbs from my little tiny tubers that I planted last spring...I have a ways to go.

It's true what you say about the crosnes, they do look insect-like and remind me of pupas. Some gardening books mention that crosnes rarely make a big harvest, which was true when I tried to grow them.
Where did you purchase the original stock? I believe crosnes were available in the Shumway catalog once, but I haven't received a new issue yet.

Could anyone tell me where to buy the tubers or seed for these crops? I searched Shumway but they do not list the crosnes. Thank you

So, oldherb, did you get all your crosnes or did they resprout the next year? I planted some two years ago in a restricted location, but for various reasons haven't dug any yet. I'm going to see what I have later this month.

Also, I'm curious as to how you ate them. Just raw, or did you cook them? I've been seeing them on various menus for several years now. Most of the people I've talked with who have eaten them seem to prefer them cooked. Anyway, I'm anxious to try them if I have some to harvest.

Pionion, there's an online article from Mother Earth News that lists some sources for crosnes. I got mine from Goodwin Creek Gardens.

Here is a link that might be useful: MEN article on crosnes

The cousin of Stachys affinis, stachys floridana -- aka Florida Betony and "hedgenettle" is the bane of lawns in the Sunshine state... well, not mine because I eat them. It is fair to say millions are spent to stop S. Floridana whereas all is needed is an appetite. At some $17 a pound are you sure you don't want to grow S. Affinis?
