Green Wall Plant Feature: Sempervivum 'Cobweb Buttons'

Sempervivum 'Cobweb Buttons'

(Sempervivums are also known as Hens and chicks.)



These 'Cobweb Buttons" are adorable. Super rounded rosettes of tightly packed, bright green leaves are thickly laced with fuzzy white webbing.

The rosettes develop by offsets into crowded, richly textured mats. In summer the older rosettes send out thick stalks bristling with stubby pointed leaves and topped with dense clusters of pinkish-white blooms. Rosettes die after flowering.

Like other succulents, sempervivums don’t ask for deep soils but prefer an infertile sharply drained growing medium. Wet winter conditions will kill them.

Plant them in sandy gravelly infertile soil in sunny rock gardens, stone troughs, or crevices. And as you can see the are very happy in our green wall. Offsets may be severed and rooted in sand to create a whole new plant.
