Sempervivum arachnoideum f/ Val Miniera is a frost-hardy alpine succulent belonging to the Crassulaceae family, native to the rocky, exposed mountain terrain of Europe. It grows naturally in harsh subalpine conditions where thin soils and freezing winters are standard, making it one of the toughest clustering succulents you can grow.
Dense, silvery-white webbing stretches across each rosette like fine spider silk, giving this cobweb houseleek its distinctive appearance. The rosettes are compact and tightly formed, with fleshy, pointed leaves edged in that signature woolly threading. As a clustering succulent, it steadily produces small offsets that fill containers, troughs, and rock garden gaps with multiple rosettes.
Like all hens and chicks, the main rosette flowers once before the surrounding offsets take over, keeping the plant cluster full and lively year after year. A drop in nighttime temperature can encourage blooming. The plant produces pollen and allergens when it flowers, which is worth noting if you are allergy-sensitive.
Move it outside in summer and it handles balcony wind and drafty spots without trouble. You can leave it up to ten days without water. It tolerates the dry heated air of indoor spaces equally well. A roof or cover during prolonged heavy rain will keep the rosettes looking their best. It works well in rock gardens, alpine troughs, and container arrangements.

Sempervivum arachnoideum f/ Val Miniera grows well in partial sun to full sun, needing at least four to six hours of direct light daily and rotating periodically for balanced rosette growth.
Water it deeply but infrequently, roughly every 10 to 14 days in summer and even less in winter, letting soil dry completely between waterings.
Sempervivum Arachnoideum Val Miniera does best in a gritty, fast-draining mix such as cactus soil blended with perlite or coarse sand at a roughly 1:1 ratio.
It is frost-tolerant and handles temperatures well below freezing, remaining hardy through roughly -20°F depending on conditions and drainage.
