Description
Sempervivum arachnoideum bryoides is one of the smallest houseleeks available. Forming dense mounds or carpets of tightly packed individuals which only measure up to 1cm each. The oval, fleshy green leaves are tipped with red and covered in a fine web of white hairs. Interestingly, the red colouring becomes more intense depending on the conditions. When a rosette is mature it produces an arching stem of pink flowers in summer. Once it has flowered that rosette dies but is quickly replaced by offsets. The moss-like cobweb houseleek makes an interesting specimen plant for the alpine house as well as an attractive textural plant for the rock garden.
A hardy plant which should survive normal winter conditions outside, especially in well drained soil with protection from winter wet. If grown in pots it is recommended to place in a sheltered position for the winter.
