Sedum spurium 'Green Mantle' (also called yellow stonecrop)
Mat-forming, semi-evergreen ground cover plant with bright green foliage and clusters of yellow flowers in summer. Useful for poor and/or dry soil, rockeries and edging.
Very attractive to bees, hoverflies and butterflies.
Evergreen in mild areas (but not here in north Lincolnshire), flowers in summer.
Habit - lax, mat-forming. H: up to 10cm S: up to 50cm.
Stems - lax, trailing, green to mid-brown.
Leaves - fleshy, obovate, glossy, serrated, bright green. Leaves form in tight whorls in spring before opening out more.
Flowers - clusters of bright yellow, star-shaped flowers borne in summer.
Well-drained, neutral to alkaline.
In cold areas it may lose its leaves so cut back bare stems - it will sprout again in spring.
May be troubled by slugs and snails, and by vine weevils if grown in compost.
By seed or division in spring. It also sets a few seeds, but hasn't become troublesome in my garden.
