Sorry Phloxie, it is one plant I have trouble getting to grow. Yes I know strange isn't it?

Its quite common in the alpine section of most gc if that's any help.

Hi SBG
Thanks for your reply. I managed to buy one pot of Cerastium Tormotensum plant at a GC yesterday the only pot they had. I cannot tell you the number of GCs I have tried before finding this one. I have also sent away to Mr Ben seeds for a packet of seeds to try growing from seed I don't know how difficult they are to raise this way.
The Coryadalis plants you so kindly sent me are thriving. I potted them into 9cm pots on arrival, they made fantastic roots and I actually planted them out into the garden yesterday morning. Once again thank you for those. Regards
