It is a crevice plant,
and so on finishing the construction of our first
'Czech' crevice garden last May, this was the first
plant to go in. So far, as you can see from the
pictures, it seems happy.
According to a piece
on the NARGS
website, it comes in two forms, one on granite as on
Pike's Peak, and the other on limestone - we hope ours
is compatible with County Down silurian shale.
