Ginger (zingiber officinale) Photo ,that you buy in the produce section of your grocer, is a live rhizome, that can easily be grown. It becomes a tall bamboo-like plant, that is really tough, and can take a lot of abuse. The root grows very similar to an iris, sending out nodes, and spreads, fairly rapidly, filling the pot. They can be removed, with a knife, and washed. You now have a constant supply of ginger. I once had one, that filled an 8" pot, it made a pretty plant for one corner of my living room.
