I see in another thread that Chris Boulby is the "curator" of the

collection of Diaschias.

I have a question, which is applicable not only to that collection, but
to
all collections of plants whose hardiness is somewhat on the iffy side:

Do you have to take cuttings annually of every variety in the collection
in
order to be insured against winter losses, or is the collection kept
under
glass? (Or both?)

One point Chris mentioned very quickly and it's quite important. That is
the
fact that in many cases there is more than one National collection -at
least
for the more popular genera. More 'insurance'

I understand that. I also appreciate the wisdom of offloading the risk
somewhat by offering specimens to trusted friends and organisations.
