Sempervivum

Common name: Hens and chicks · Houseleek · Liveforever

Sempervivum is a genus of hardy, rosette-forming succulents native to the mountains of southern Europe and the Mediterranean. Each rosette multiplies by producing offsets on short stolons, quickly forming dense mats that tolerate cold, drought, and poor soil.

Care summary

Sun Full sun
Water Drought tolerant; water sparingly
Soil Poor, gritty soil with sharp drainage
Hardiness Zones 3–8
Mature height 5–15 cm (2–6 in) rosettes
Pet safe Non-toxic to cats and dogs

Fun facts

  • In parts of Europe it was traditionally planted on rooftops, believed to protect houses from lightning and fire.
  • Each rosette is monocarpic — it flowers once, then dies, leaving its offsets to carry on.
  • The "chicks" are baby rosettes produced on stolons around the mother "hen."

Common problems

    • Plant in gritty, fast-draining soil
    • Let soil dry fully between waterings
    • Avoid wetting the rosette centers
    • Remove and discard rotted rosettes
    • Move plants into full sun
    • Provide at least six hours of light
    • Reduce watering on stretched growth
    • Blast pests off with water
    • Dab mealybugs with rubbing alcohol
    • Isolate infested plants promptly
    • Improve airflow around the plants
    • Remove and destroy spotted leaves
    • Avoid overhead watering
