Does anyone know a nursery that will sell Japanese Knotweed, or Mexican Bamboo?

Question:I have a huge fiberglass tub I want to grow it in. I realize it's considered an invasive species but it's very edible and quite tasty!

Answers:
Wow! I have never heard of anyone wanting to buy Japanese Knotweed. It grows everywhere here in Western PA. I also have never heard of eating it. I will do a search to find out more.

Found a little about eating it!
Next spring, the young shoots, about a foot high, can be picked and eaten raw. They are very crunchy, dripping with juice, and sour. Cooked, they can become sickeningly squishy and sweetish. Pies can be made. The oxalic acid content, however, may be high enough that you should consume only one serving a week.
