The Story
Plant Bio
Sempervivum heuffelii, sold as Jovibarba heuffelii, is a clump-forming evergreen succulent from Balkan rock outcrops and cliffs, making tight rosettes 3 to 6 inches tall by 8 inches wide with thick dark green leaves tipped burgundy under stress. Each mature rosette sends up a stout leafy stalk 8 to 14 inches tall carrying up to 40 pale yellow bell-shaped six-petalled flowers in summer.
Unlike common hen-and-chicks it produces no stolons, splitting new sessile offsets from between the leaves that can only be increased by cutting the crown apart. Each rosette is monocarpic and dies after it flowers, and in cultivation winter wet at the crown kills more plants than cold.

Planting
How to Grow
- Plant in full sun in very gritty, lean, fast-draining soil in a rockery, trough, or pot with a drainage hole.
- Set the crown at soil level and top-dress with gravel to keep leaves off wet soil.
- Water deeply only when completely dry from spring through summer, then keep almost dry in fall and winter.
- Shelter pots from heavy winter rain under an eave while leaving them out in the cold.
- Remove the spent rosette after flowering and leave the attached offsets to fill in.
Pro Tip
Keep the crown dry in winter and water only when the soil is completely dry; cold is not the limit, standing water is.
