Family

Crassulaceae

Botanical Name

Sempervivum 'Ruby Heart'

Plant Common Name

Hens and Chicks

General Description

With its symmetrical red-centered heads of fleshy blue-green leaves, 'Ruby Heart' is a garden jewel. It is one of many outstanding hybrid hens and chicks derived from alpine species native to the mountains of southern Europe and western Asia. The evergreen rosettes develop by short-stalked offsets into crowded, colorful, richly textured mats. The leaves often intensify in color in cold weather, their strong red-purple centers contrastingly boldly with frost and snow. In summer the older rosettes send out thick erect stems bristling with scaly leaves and topped with clusters of small purple blooms. Rosettes die after flowering.

Like other succulents, Ruby Heart hens and chicks don’t need deep soils but excel in an infertile, sharply drained growing medium. Winter sogginess is death to them. Europeans have long grown them on tile roofs, whence the common name "houseleeks." Plant them in sandy gravelly infertile soil in sunny rock gardens, stone troughs, or crevices. Offsets may be severed and rooted in sand to create a whole new plant. Severed offsets are also useful for filling the gaps left by dead rosettes.
