The heart-leaved globe daisy

This little carpet-forming plant is characteristic of rocky limestone terrain. Its leaves are indented at the tips, giving them the appearance of a heart - with a little imagination! The purple-blue flowers are arranged into little round heads, hence the name, globe daisy. It is a very fast coloniser and can cover stony ground and boulders... even to the point of being invaded itself by other plants once it has fixed the soil.
