This is a gorgeous, sought after, old-fashioned hardy perennial that I adore. It forms a beautiful clump of deep green foliage and produces it's 'ragged' rose-pink flowers off and on all year, including winter here in my garden. It self-seeds politely and is perfect for naturalising under trees and shrubs too. Full sun or partial-shade in most well-drained soils that don't dry out too much in Summer. 60x45cm approximately.
