Succulent perennial from the Crassulaceae family, this cultivar is a miniature form of Sempervivum arachnoideum, selected and maintained in cultivation for the smallness of its rosettes. As with 'Hookerii', it should be noted that the name 'Minor' is of old horticultural usage and its exact delimitation in relation to naturally small forms of the type species is not always clearly established in the literature.
The rosettes, barely 1 to 2 cm in diameter, are among the smallest found in the genus. They are covered with a well-developed white web, characteristic of the species, which contrasts with the green to reddish-brown green foliage. The leaves are fleshy, short, often with a tip tinged with reddish-brown. Vegetative multiplication is active and quickly produces dense, tight cushions composed of a multitude of small, similar rosettes, creating a very regular effect.
The bright pink blooming occurs in July-August on fine stems of 8 to 12 cm, but it is above all the texture of the silvery foliage and the delicacy of the rosettes that justify the interest in this cultivar, particularly suited to container compositions, wall crevices, and small-scale rock gardens.
Cultural requirements are identical to those of the type species: full sun, very well-drained and poor substrate, total hardiness in temperate climates.
