Sempervivum Arachnoideum
Sempervivum arachnoideum is a cold-hardy, rosette-forming succulent known for the web-like threads of white hairs that grow across its center. These “cobwebs” are a natural feature that help protect the plant from harsh sun. It spreads through offsets, forming a dense mat of tiny, web-covered rosettes.
