How to Grow

Propagation

Propagate by division in spring. Propagate by softwood cuttings of non-flowering shoots in early summer

Suggested planting locations and garden types

  • City and courtyard gardens
  • Cottage and informal garden
  • Rock garden
  • Flower borders and beds

Pruning

For bushy, compact plants, cut back the new stems by half in late May, this method is called the Chelsea chop; or cut back after flowering, and during border tidy ups in late winter before new growth emerges; seedheads can be left to overwinter

Pests

Garden pests such as slugs and snails can damage soft growth and vine weevil may damage roots, especially in containers. If deer come into your garden, they may browse (eat) the foliage of hylotelephium

Diseases

May be susceptible to fungal and bacterial crown and root rots on wet soil, or Powdery mildews on dry soils
