Sempervivum tectorum (Houseleek) 9 cm Pot

Growth habit & appearance: Sempervivum tectorum forms tight, architectural rosettes of thick, fleshy leaves arranged in precise spirals characteristic of the Crassulaceae. The foliage ranges from soft greens to richer reddish tips depending on sun exposure, giving the plant strong visual appeal even when not in flower. Mature rosettes occasionally produce tall, starry inflorescences that draw in bees and other small pollinators, adding ecological value to rock gardens and container plantings.

Growing conditions: This half-hardy perennial prefers full sun and sharply drained, mineral-rich soil. In Ireland it performs well outdoors through the growing season but benefits from being kept indoors or under cover during winter to avoid prolonged cold and wet. 

Traditional & herbal uses: Traditionally, the cooling succulent leaves were applied for burns, boils, toothache, and nosebleeds. The mucilaginous sap was valued for its soothing qualities in various European folk traditions. Ecologically, the rosettes provide microhabitats for small invertebrates and contribute to biodiversity in dry, stony garden settings.

Maintenance & harvesting: Maintenance is minimal: provide strong light, avoid overwatering, and ensure excellent drainage. Rosettes naturally produce offsets that can be divided and replanted or potted on to expand stock. Harvesting traditionally involved removing mature outer leaves as needed. Keep plants indoors or under cover during the Irish winter to protect them from excessive moisture.
