Brilliant question. I never thought of that. I have tried dates, figs, coconuts, citrus, taro, and others, but didnt think of yucca. That would be a great addition.

Yuccas are pretty common, and cheap, in the garden centers, but you could ask the GardenWeb Cacti and Succulents Forum.

I was dumb enough to ask this same question a few months ago. That is not a true Yucca Tuber. I forget what I was told it was, but it is not Yucca. It is that plant that South American Indian tribes chew up, wash out the toxins and ferment for an alcoholic beverage.

I kept mine in a pot and it has done nothing. I was told that they prep these for the supermarket by waxing them over after soaking them to leach out the toxins.

I know it is not a true yucca but I know people here have grown stuff out of the supermarket so I thought I would run it by the forum

This post is a little off-topic for a Palm forum, but interesting. It's not a Yucca, it's a Yuca....aka Cassava root. It's also what Tapioca is made from, and no, I do not think replanting the root is a viable method of propagation.

More info can be found at the Dave's Garden link below, or Wikipedia.

Yes, "yuca" is what they call cassava root in Hispanic/Latino restaurants & grocery stores. It's especially good deep-fried (but then what isn't!). The species is Manihot esculenta; a close relative is Manihot grahamii, a beautiful and not-quite-hardy-in-my-zone subtropical plant that grows into a small tree:

Just an update ...

I pulled the Manihot root that I had planted up and it was soft, mushy and rotting. So no, I'd say you are not going to have any luck planting this thing.

To get real Yucca growing for you, it is incredibly easy to propogate by cuttings. Just find a Yucca Elephantipes for example, and cut off one of the leaf buds with a small portion of the heart wood. Plant this and you'll get a new Yucca, almost assuredly.

We have so much of that yucca cane here people just cut them a piece off plant it and it grows. You can't kill that stuff !

Has anyone ordered cycad seeds from Encephalatos World?
