Long known as Polygonum vacciniifolium, this is a lovely, easy, spreading plant with lots of interest. It grows as spreading, almost woody stems, bare brown in winter but shows its small glossy leaves in spring.
Long, pointed flower spikes - deep rose-pink opening paler pink to give a two-tone effect - appear in late summer and last well into autumn when garden colour is scarcer. The display ends when the leaves turn red before they fall. It looks especially good where it can trail over the edge of a wall.
About 15cm (6") high when flowering, wide-spreading where happy but may be clipped back in early spring.
