Noteworthy Characteristics

‘Superba’ is a vigorous compact cultivar of Himalayan fleece flower. It is a low-growing, mat-forming perennial that grows to 4-6” tall and spreads indefinitely by trailing stems to form an attractive ground cover. Mostly basal, deep green leaves are narrow oblanceolate (to 4” long). Leaves turn bronze in fall. Dense, erect, 3-inch spikes of tiny pink flowers appear above the foliage mat over a long, early summer to fall bloom period. Synonymous with Polygonum affine ‘Superba’. The cultivar ‘Superba’ is also considered to be synonymous with ‘Dimity’.

Problems

No serious insect or disease problems.

Garden Uses
