Sempervivum arachnoideum, sometimes known as cobweb houseleek, is a perennial plant of the genus Sempervivum. Its name arachnoideum refers to its furry central rosettes, resembling spider webs.

S. arachnoideum is a low-growing, evergreen perennial, often cultivated in rock gardens, that grows to 0.1m by 0.15m in full sun and well-drained soil. It flowers in July, with pink flowers that are raised on stems and hermaphrodite (having both male and female organs).
