As the sun goes down this perennial which has flowered all day will produce a lovely, partly vanilla scent. The flowers are single and cup shaped with a white centre and deep pink reverse. Dwarf and compact it is best suited at the front of a boder or in a patio container near the house so the fragrance can be appreciated. Flowers May-September. Height 20-30cm (8-12); spread 50-60cm (20-24).
