How to Grow and Care

Hylotelephium telephium 'Purple Emperor' grows best in full sun exposure areas. In hot microclimates, this plant tolerates partial shady conditions. Good-draining soil is required for this plant, which does not tolerate wet roots. Stonecrop plants work well tucked into soil pockets on piles of stone in rock gardens. They are also suitable to grow in containers.

The best time to plant Hylotelephium telephium 'Purple Emperor' is in the spring. Place the root ball in good-draining soil so that the top of the root ball is level with the ground. Spacing for this succulent is between 6 and 24 inches (15 and 60 cm). Plant closer together to speed up the amount of time it takes to cover an area.

Stonecrop prefers dry conditions and only needs occasional watering once established. Soak the soil heavily right after planting and then again before the cold weather occurs. Once the extensive root system develops, let the soil dry out between watering.
