A mat-forming hardy succulent, it has blue-green, rounded leaves with pointed spiny tips, arranged in rosettes. Erect, hairy stems, to a height of 30 cm (12 in), bear pinkish-red star-shaped flowers in summer.
History and traditions
In the folklore of most European countries, houseleek is dedicated to Jupiter or Thor and was deemed to provide protection from lightning. It has been planted on thatched roofs or in the crevices of roof tiles ever since the Emperor Charlemagne, 747-814 AD, decreed to this effect. The second part of the common name, houseleek, is from the Anglo-Saxon word for plant, leach. Its Latin name refers to its ability to withstand any conditions, and comes from semper, always, and vivum, living or alive. The specific name decorum is a reference to its roof habitat. This herb has been used since the time of Discords and Pliny as a soothing agent for skin complaints. And Culpeper, writing in the 17th century, suggests a first-aid measure, which is equally valid today: “the leaves being gently rubbed on any place stung with nettles or bees, doth quickly take away the pain”.
Habitat/distribution
Native to southern Europe and western Asia found on rocky slopes and in mountainous areas. Introduced and widely grown elsewhere.
Growth
Thrives in gritty or stony, sharply drained soil and withstands drought. The easiest method of propagation is by separating and replanting offsets in spring.
Uses
Medicinal
The leaves are made into infusions, compresses, lotions and ointments, or cut open to release the sap and applied directly to insect bites and stings, sunburn, skin irritations, warts and corns.
