Sempervivum calcareum 'Grigg's Surprise'

Highlights

Sempervivum calcareum 'Grigg's Surprise' (aka S. calcareum 'Monstrosum'): A rare monstrose cultivar for the collector. Instead of the normal flat-leaved rosette, this variety grows as a mass of long, slender quills. The leaves are blue-green and tipped in deep burgundy. This hard-to-find cultivar has a unique look and always adds interest to a collection.

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 thrive through winter under an insulating blanket of snow. Protect from heavy rains and standing water to prevent rot.
