Sempervivum 'Festival' (Cmiral): Shows bright colors in every season, from lime green with red margins in summer to a bright cerise and blue-green in winter. This medium to large rosette produces plentiful new offsets in spring. 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 85F. They are incredibly frost hardy and will happily overwinter under a blanket of snow. Protect from heavy rains and standing water to prevent rot.
