My Dad grows bamboo as a privacy fence, and cuts it back periodically to keep it contained. (Grows wild, not sure what kind.) While cutting one day he found a really strange one, pictured below, hand for scale. Does anyone know what happened here? Also, which forum would be best to find some bamboo experts?
Weird...
Base of the weird one.
Here's what it normally looks like, over 8 ft. tall.
