Sempervivum 'Hepworth Hybrid': An American cultivar with lightly velvety leaves. It mostly stays a silvery green but the leaf tips can take on a reddish flushing when gently stressed by bright sun or frost. Hens & Chicks need plenty of outdoor sunlight to show their best colors and maintain a tight rosette form. They thrive in gritty, well-draining soils and pots with drainage holes. They produce new offsets or "chicks" on stolons. These chicks can be left to form tidy clusters or removed to share and transplant. Sempervivum do most of their growing in the spring and summer, and will thrive with weekly watering and afternoon shade if temperatures exceed 80F. They are incredibly frost hardy and will happily overwinter under an insulating blanket of snow. Protect from heavy rains and standing water to prevent rot.
