How to Grow

Cultivation

Grow in moist but gritty well-drained soil in sun, in a rock garden, scree bed, or trough, in vertical crevices in rock-work or walls, or in an alpine house, where it can be protected from winter wet, in a mixture of sharp sand and leaf mould

Propagation

Propagate by rooting single rosettes as softwood cuttings, and keep moist by watering from below

Suggested planting locations and garden types

  • City and courtyard gardens
  • Cottage and informal garden
  • Gravel garden
  • Rock garden
  • Patio and container plants

Pruning

No pruning required, but removing dead rosettes will reduce the risk of fungal infections

Pests

May be susceptible to aphids, root mealybugs, root aphid, and glasshouse red spider mite; birds may tear at rosettes

Diseases

May be susceptible to fungal diseases in damp conditions
