Does anyone know what this perennial is?, the foliage is a pale green colour and it's about 15-18 inches in height. I want to buy some more to put in the rockery and in a dark border.
Thanks Hammerman, can I ask, the picture in the link Chris put up has slightly different flowers to the one in my garden, it says it's Cerastium Tomentosum, from the description it gave it seem it's shorter and more compact than mine, would they be a different variety of Cerastium do you think?
