Hi Jane:

I think "Pink Diamond" is a hybrid of D. ida-maia and D. multiflorum.   D.
multiflorum will often exhibit a slighty twining stem - not like the D.
volubile, but it definitely twists some.  An oddity I thought I would
mention, is that I have often found D. multiflorum making a "double-decker"
flower, the main umbel, then a short stem with a small umbel above it.  I
have gathered seed from plants like this, and so far they haven't done the
same thing in cultivation, although maybe it's a question of greater
