Sedum hirsutum, commonly known as hairy stonecrop, is native to southwestern Europe, including Portugal, Spain, France, and Italy, and northwestern Africa, including Morocco. It grows on shelves or cracks of rocks, always on acidic, dry substrates, and is often associated with accumulations of mosses.267 It prefers shaded places to sunny. The plant species is characterized by its distinctive appearance, including its small, hairy leaves and delicate clusters of flowers that bloom from June to August. It produces clusters of small star-shaped flowers that can vary in color, ranging from white to yellow to pink, depending on the specific variety.268
Etymology
The genus name Sedum is derived from the Latin word “sedere,” meaning to sit. This is thought to refer to the characteristic growth habit of many species within the Sedum genus which often appear to sit or sprawl low to the ground. The species epithet hirsutum is derived from the Latin word “hirsutus,” which means hairy or hirsute. This likely refers to the characteristic hairy or rough texture of the leaves or stems of Sedum hirsutum. So, the name Sedum hirsutum essentially means “hairy Sedum,” referring to the plant’s hairy or rough foliage.269
Horticulture, Ornamental, and Other Colorful Uses
As a low-growing perennial, hairy stonecrop requires minimal maintenance once established. It is relatively pest and disease resistant and can thrive in poor, sandy, or gravelly soils, making it an excellent choice for xeriscaping or low-water gardens.270
Ecology
Hairy stonecrop is a prolific spreader, but not through seeds! Instead, it spreads primarily by vegetative propagation. Leaf and stem fragments can detach from the main plant and take root easily, allowing the colony to expand and create a dense carpet.271
Its trailing stems and dense foliage provide excellent ground cover and can help control erosion on slopes. It also produces clusters of small, star-shaped flowers in shades of pink or white during the summer months. These flowers attract pollinators such as bees and butterflies.272
