Those who have grown bamboo in a temperate climate are likely to wish they never did. Once a temperate bamboo gets going it's almost impossible to keep under control, shooting up in all sorts of inconvenient places and doing more damage to lawns than pesky moles.
But for us lucky folks living in a tropical climate, we grow
clumping bamboos, which are sooo much easier to maintain.
This is
Bambusa malingensis, a particularly thickly-clumping, vigorous species that I really must get round to thinning out. It's about 25' now and can get to around 35'. It's a graceful plant that will bend nearly horizontal in our frequent, strong winds.
It started off as a weedy thing about seven years ago, and now it blocks out the view of (and from) the bridge, which is what is was intended to do.
I got it from Daniel and Martha Holmes of
Holmes Bamboo in the Redland. If you're in the market, check out their website.
