Awesome, thanks.

When you say cut back by half, do you mean just prune down the long stalks by half? Guess I'll do some research.

#3 is Manihot esculenta 'Variegata', Cassava.

Yes, cut the limbs back by 50% or half. You can root them pretty easily, especially if the 3rd one is cassava. People are always looking for cassave cuttings, so you might want to try to sell some on Craigslist.

@eric I thought so too, but cassava has different leaves with more lobes, and does it have those seed pods? Mine never did.

ETA: guess it could be cassava, because it does get seed pods. It's just that cassava leaves have at least 5-7 lobes, and these seem to have 3 at most. I could be wrong.

Cassava has palmate leaves but this one has dropped some for the winter so some of the leaves are missing leaflets. You can see some entire leaves with leaflets in the upper left corner of the pic.

Cassava does not have leaflets. It has deeply lobed leaves. Look closely at them.
