Edible hardy bamboo?

Anyone know of a hardy bamboo that makes good eating? Preferrably a clumping bamboo- as oppose to a running one.

Alternatively, just how invasive are running bamboos? I'm looking at Phyllostachys Aureosulcata, as it claims to be only 'moderately invasive', and edible.

I'm in the UK, urban garden.. I want the bamboo as a screen between me and next door- if I can also grow garden canes and eat some- then its a winner. But I don't want o spend the next 3 years digging it out if it becomes too invasive... like I've had to with the Japanese Knotweed we inherited....

Google "permies bamboo." Lots of good info.

You need to maroon running bamboo on an island or something.

Well, good news is that there are over 200 species of edible bamboo and you are bound to find one that is yummy. I would be careful about eating the raw bamboo because bamboo's bitterness comes from taxiphyllin which becomes hydrogen cyanide. Therefore, I advise boiling the shoots in water before eating to get rid of the taxiphyyllin. Here is a link explaining more about eating and using bamboo:

This is a nice little online PDF with more specific cooking information (boil in water for 20 minutes) and a few recipes to inspire your creativity:

Lastly, there is an article that explains how to grow bamboo and control it:

I hope some of this is useful to you.
