Sedum forsterianum, the Rock stonecrop, is a species of flowering plant in the genus Sedum in the family Crassulaceae.

Description

edit

Sedum forsterianum

is a low-growing perennial with stubby, succulent, untoothed, alternate leaves. These are often greyish-green, and may turn pink in dry conditions. The flowers are short-stalked and star-like, white (sometimes tinged pink), with ten contrasting stamens and five carpels. The fruits are red.[1]

Common name: Rock stonecrop Family: Stonecrop (Crassulaceae) Scientific name: Sedum forsterianum Main flower color: Yellow Range: Native to Wales and southwest England, and introduced to other regions of the UK Height: Up to 20 cm Habitat: Well-drained, rocky places, often coastal, including grassland and waste ground Flowers: Yellow, with five petals, five carpels and ten stamens, produced in a dense, compact cluster, pendent in bud, otherwise erect. The hairless, light green calyx is divided nearly to the base into triangular lobes. Flowers are held at the tip of the relatively tall stems. Leaves: Short, fleshy, linear, D-shaped in cross-section (flat on top); at intervals along the flowering stems and more densely at the tip of non-flowering stems Season: June to August[2]

evergreen perennial, height 35cm, habitat rocks, screes and rocky woodland, distribution- north-west Europe as far north as Scandinavia, rare in Ireland, flowers june and July, in gardens, well drained soils, full sun, rock and gravel gardens, mat-forming rock stonecrop is often mistaken for the reflexed stonecrop (sedum rupestre). It produces the same crowded clusters of starry flowers, which are bright or pale yellow, at the tip of fleshy, pale pink stems enveloped in grey, succulent, pointy leaves. The most obvious difference is that the non=flowering stems have distinctly bushy clusters of foliage at the tip and any dead leaves persist, clinging on underneath - reflexed stonecrop drops its dead leaves. Given space, rock stonecrop will happily thrive in a rock garden. [3]


A succulent perennial with heads of yellow, star-shaped flowers on the ends of the upright branches. The non-flowering shoots terminate in clusters of linear leaves (with old dead leaves persisting on the stem below).

Introduced. Native in southern Great Britain and the European continent. Established on old stone walls.

Often mistaken for Sedum rupestre, which is a similar but more robust species found in identical habitats, and differing in having no dead leaves below the terminal clusters.

All names: Sedum forsterianum Smith; Sedum elegans Lej.; Sedum rupestre auct. non L.; Sedum forsteranum Sm.[4]

Sedum forsterianum ssp. elegans ‘Silver Stone’

Rock Stonecrop USDA Zone: 4-9 Plant number: 1.486.100

Colourful for both its flowers and foliage, this evergreen Stonecrop selection is ideal for the front edge of a sunny border, in containers or in the rock garden. If forms a low mound of blue-green needle-shaped leaves,with upright stems in summer that bear clusters of bright yellow starry flowers. Adapts to most soil conditions so long as drainage is reasonable. Easy to increase by dividing in spring or autumn, or just breaking off pieces and sticking them in the soil. Prune in spring if plants become unsightly from winter. Quite possibly hardy to Zone 3 or colder.[6]

Sedum forsterianum occurs in western Europe, including Norway, Sweden, Ireland, Great Britain, France, Portugal and Spain.[1] It is usually found on dry rocks, walls and sand dunes, often near the sea.[10] It prefers thin, acidic soils and thrives in rock crevices and on cliffs, and also grows inland on walls and hedge banks.[11] In Great Britain, it is much more common in the west of the country than in the east.[12]
