There are two basic types of plant in this genus (this species is a crawler):-
'crawlers' are species with horizontal roots that often spread freely, with new plants being formed at intervals along the root. These species are useful for naturalising, but they do not flower very freely in the cool summers of Britain. 'clumpers' have vertical roots, they form slowly spreading clumps and produce offsets around the crown. These forms flower much more freely in Britain.The flowers have a fruity perfume like that of ripe apples. The variety rosea is more strongly fragrant.
