Dianthus alpinus 'Albus' Dianthus alpinus 'Albus' Dianthus alpinus 'Albus' Large white flowers with nice pink centres on neat green mounds. £2.75 Out of stock. A good white form of D. alpinus, raised from cuttings. Large white flowers with dark pink central zoning opening from dark buds in late spring/early summer. Very neat mats of glossy, mid-green leaves. A desirable little plant, ideal in a stone trough or on the rock garden. About 7cm (3") high when flowering. Like all the D. alpinus, it seems to prefer a slightly richer soil, loamy, but well-drained. Very hardy and tough - but neat and pretty.
