Santolina

Cotton lavender. From dry, rocky areas of the Mediterranean and one of the mainstays of our dry Gravel garden. All are highly valued for their evergreen aromatic foliage forming low bun shaped plants to contrast with taller verticals.  The flowers too are attractive displaying button like centres surrounded by looser outer florets. All benefit from a trim over after flowering and a harder prune in the spring otherwise the plants rapidly become straggly.
