We've been collecting some amazing bamboo from two different groves and they've already started rooting out. We have some 25/30' Phyllostachys vivax (Giant Timber Bamboo). Some of the culms are over 4" !

We also have some Phyllostachys nigra (Black Bamboo). These are a bit younger and don't get as large as the Giant Timber, but have black canes that add an instant accent to any landscape. These are about 15-20' right now.
