Are you actually a bamboo specialist who knows what he is doing, and
really really wants to add this one to his collection of 20 other
bamboos? Or are you just someone who has heard of blue bamboo and is
going "ooh wow I want blue bamboo". If the latter, I'd wouldn't bother
with H hookeriana, because it is very difficult to get it do well in
Britain, and you really need to live in one of the mildest corners of
Devon or something. Carwinion had a good grove, but of course that is
one of the mildest corners of Cornwall. Many people have tried it, and
even if they kept it alive they gave up with it as it just didn't "do"
for them. In Britain you'll get the blue bamboo experience much more
effectively from one of the Borindas - Jungle Giants do a good range of
them - or something like Thamnocalamus crassinodus
If you know you really want just this bamboo, then if you spell it right
you might have a better chance, it's hookeriana (I know it seems
illogical and it is often misspelled for that reason). With the correct
spelling, google did find me a couple of people claiming to sell it but
they aren't people I've heard of so I'll leave you to follow up with
them. Bamboos are slow to propagate, and some are rather difficult, so
the less commonly grown ones tend to only appear on the market
intermittently when someone has decided to do it and succeeded. It is
sensitive, so nursery stocks might have been reduced, or even
devastated, in the recent cold winters.
If the above doesn't help, I would talk to Nick Macer at Panglobal
Plants, he might have it intermittently, or if he doesn't, he might tell
you who has it, he seems to have the most eclectic bamboo stocks in the
country, and far from everything that he has is listed on his published
stock list. I would also join the Growingontheedge.net forum, a few of
the members there grow it or have tried growing it, and so might be able
to give you some hints. It may be that you have to go to the
Netherlands or France to get it, and someone might point you in the
direction of sources there, if you are that keen to get it.
hardytropicals.co.uk is another forum it might be worth joining and
asking on.
