Sempervivum arachnoideum Cobweb

Sempervivum arachnoideum ‘Cobweb’ is one of those deliciously peculiar little succulents that looks as though a spider moved in and decided to decorate. Each tight green rosette is threaded with fine white webbing, creating that signature cobwebby effect that makes the whole plant look both enchanting and slightly unreal. We adore it tucked into rock gardens, stone crevices, troughs, and pots, where its intricate texture can really be admired up close. It loves full sun, well-drained soil, and leaner soil, and once established, it is wonderfully drought-tolerant. Over time, it multiplies by offsets, gradually forming a low colony of charming little rosettes. The foliage stays quite petite, typically about 1" to 3" tall, with individual rosettes only a little over an inch across, though flowering stems rise higher in season.
