I have the clumping variety of bamboo. The caines have shoots at intervals. Are these shoots edible?
Bamboo Shoots for Eating

It would be best to find out exactly what species you have (there are over 1500) and look up whether that one is edible. Some bamboos have a cyanide compound in the shoots and need to be cooked thoroughly (by boiling) to remove that compound. However, all the species are thought to be edible after cooking. As long as you can be sure it is a species of bamboo, it should be possible to boil it to make it safe as described here:
If it tastes bitter after boiling, it probably still has some toxin in it.
