Sempervivum tectorum, also known as Hens and Chickens, Jupiter's Eye (or Beard), and Houseleek, has been a favourite herb since ancient times. The plant is native to the mountains of Europe and the Greek Islands.
Sempervivum has also been called Thor's Beard, Bullock's Eye, Sengreen, Ayron, Ayegreen, and Donnersbart.
History of Sempervivum
M. Grieve tells us in A Modern Herbal that, “the generic name Sempervivum, from the Latin semper ("always") and vivo ("I live"), refers to its retention of vitality under almost all conditions, and the specific name tectorum bears witness to its usual place of growth—a roof.”
The Romans grew Sempervivum in vases at the entrance to homes for prosperity, and to show esteem to Jupiter. This was thought to provide protection from storms, fire, and lightening, all associated with Jupiter.
The custom of planting Sempervivum on rooftops prevailed for centuries across Wales, England, France, and much of Europe.
Medicinal Uses of Sempervivum
Hens and Chicks can be used like a weaker version of Aloe Vera. The bruised or torn leaves can be applied to burns or skin inflammations for relief. Folklore also says this herb will remove warts and corns.
While some sources do list this plant as a "green herb," or one cabable of being ingested, be cautioned that in large doses the juice of the leaves can be emetic and purgative.
Gardening with Sempervivum
Sempervivum is an attractive, easy-care herb for zones 5-10, and can stand some drought. It does very well in rock gardens, along old walls, edging pathways. The herb will spread rapidly by offshoots, which can be left to form an attractive matting of plants, or rooted separately for use in other parts of the garden.
The herb will produce sparse purple flowers in July on stems that shoot upright up to a foot in height. There is also a variation of Sempervivum available in a deep maroon color.
