Sempervivum ‘Arctic White’ has a ghostly, glowing appearance. In fact, it looks like it’s covered in many thick layers of spider webs – hence its species name, ‘Arachnoideum’! Planted solo or with compatible plant pairings, ‘Arctic White’ stands out as quite cute and unusual. Planted en masse, however, it really makes an impact – like a carpet of spider webs!
