I've got some bamboo seedlings for swapping:
Bambusa lako - Timor black bamboo
Dendrocalamus Asper
Dendrocalamus Strictis
Moso Bamboo
I also have other cold hardy bamboos including some very rare ones that I'd be prepared to exchange for interesting citrus plants (or budwood).
Am particularly interested in:
Phyllostachys aurea
Phyllostachys aurea 'Koi'
Phyllostachys aurosulcata 'Harbin'
Phyllostachys atrovaginata
Phyllostachys nigra 'shimadake/mejiro/Megurochiku/Punctata'
Bambusa textilis
other variagated bamboos that are cold hardy - inc some of the more unusual moso variants. See here:

Also interested in other fruiting/'useful' plants as well as bamboo - see my other posts on this forum
