type of peremnial yuca with edible leaves.

Hi, i want to plant in my land yuca plants, but the ones that usually farmers plant here in Peru are not peremnial and the leaves cannot be eaten.

So i was wondereing : which type of yuca can i plant that is peremnial and has edible leaves? and where can i buy the seeds?

I also would like to know here can i buy seeds of comfrey , it seems nobody sells seeds of comfrey in my country. any idea?

cheers

Hi,

I have bought seeds from Yucca baccatas, because the fruits are edible, and they germinated.
Pfaf article says the leaves are edible too.

By "yuca" do you mean Cassava? If so, I think the one you want is Manihot esculenta.
