Bottom heat could help like soil cable in sand, they like their heads to
be coolish. If it's very rare then maybe it's a swine to propagate?
Colvilei is awful to root, weryiana is a doodle, so it helps to know
which one it is.
There is a silvery leafed variety that is almost impossible, can't
remember the name but it was at Chelsea about four years ago, has
slender long silvery leaves and insignificant flowers. I thought it was
silver ghost or silver wedding?

This variety is as I said in the original posting a variety of Davidii.
It is not rare because it is difficult to propagate. It is rare because it
is relatively new in cultivation. It has the standard colour flower but a
later flowering season. Indeed the parent plant is still flowering and
consequently attracting a lot of late butterflies when a lot of flowers
they would otherwise use have finished.

The parent plant was , I believe, obtained from its discoverer who found
it in China.

I think the standard colour is probably best for butterflies as it is the
natural colour which I would expect to have evolved for maximum
pollination.
