A 30' tall bamboo would probably have a 30-40# root ball, and be too tall to ship anywhere in any case. How are you proposing to get hold of such a plant? Also, since a plant like this would be fairly pricey if purchased, you either need to find a very generous donor, or offer more than seeds in a trade.

Or, are you talking about someone giving you a small division of a bamboo that will eventually reach 30'?
