I am no cuttings expert but given a choice between those above, I
would vote for the cold greenhouse.

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?
