Lychnis flos-cuculi 'Petit Henri'

Dwarf form of this evergreen sun perennial with cheerfully fluffy double white flowers somewhere between a pom-pom and a many-pointed star which rebloom from early spring onwards with deadheading and are further complemented by maroon tinted basal foliage. Plays nice with it's smaller sister 'Petite Jenny' or perhaps half-sister as this one seems to have gained some French parentage.
