How do I know this? Growing up, my next door neighbors kept a traditional Japanese backyard complete with a forest of bamboo (my dad has spent the last 23 years trying to stop it from expanding into our yard). During bad ice storms the bamboo would bend with the weight of the ice, forming little caves on our yard, but it would never break.

Bamboo is very flexible and is used to build earthquake resistant housing. For more information on bamboo, visit TreeHugger.com.
