Recently this little geranium was discovered in the Biokova mountains in what was
then Yugoslavia, it is a natural hybrid between two species of cranesbill.

I have them growing in pots and hanging baskets, they are very easy to propagate
from cuttings or offshoots, they share pots with other taller plants quite readily.
I can imagine them making a lovely border in the garden, I have yet to try this.
