Care at a glance

Light

Aim for at least 4-6 hours of direct sun on the leaves. Requires full, direct sun for 5–7 hours daily, reflecting its exposed mountain habitat. A south-facing outdoor position or large, unobstructed south-facing window indoors is ideal. Shade causes stretched, pale rosettes that are susceptible to rot. If your only bright window faces south, that's perfect for cloud liveforever — same window any aroid would fry on.

Watering

Watering cloud liveforever: every 1–2 weeks in cool season (october–april); completely withheld june–september. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Mimic the cool, wet winters and bone-dry summers of its mountain habitat. Water moderately in the growing season, allowing the soil to partially dry between waterings. Cease watering entirely in summer. Cool temperatures during winter watering reduce rot risk. Never water overhead.

Soil and pot

Cloud Liveforever grows best in rocky, gritty, well-drained alpine or cactus mix. Use a mix of 60% coarse pumice or perlite with 40% gritty loam. A slightly acidic to neutral pH (6.0–7.0) is appropriate for its mountain granite/schist substrate origins. Shallow, wide terracotta pots enhance drainage and temperature cycling. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Cloud Liveforever sits happiest at around 35–60% humidity and 2–26°C (36–79°F). Tolerates the moderate, cool humidity of its mountain cloudzone habitat. Cool, moving humid air is acceptable; warm, still humidity is harmful. Provide good ventilation indoors and avoid placing near heat sources in winter. If you keep the room above 2–26°C year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed cloud liveforever sparingly. Feed once in November with a very dilute (quarter-strength) balanced fertiliser and once more in February. No feeding in spring through autumn. This high-altitude species thrives in low-nutrient conditions and does not require regular fertilisation. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on cloud liveforever in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Heat stress and summer rotBeing from cooler mountain elevations, this species is particularly sensitive to hot, wet conditions. Even mild watering during warm dormancy triggers rapid rot. Keep strictly dry above 22°C and move to the coolest available position in summer.
  • Root aphidsRoot aphids can colonise the root zone unseen, causing wilting and poor growth despite correct watering. Unpot to inspect roots; treat with a systemic soil drench or repot into fresh, sterile gritty mix.
  • Insufficient winter chillThis mountain species benefits from cool winter temperatures (5–12°C) during its growing season to remain compact and flower reliably. Kept too warm indoors in winter, it may grow weakly and fail to produce flowers. An unheated greenhouse or cold windowsill is ideal.

Propagation

Offsets, where produced, can be removed in early autumn, calloused for 2–3 days, and planted in barely moist gritty compost. Seed sowing in autumn at cool temperatures (8–14°C) is effective; germination may take 4–8 weeks. Keep seedlings cool and do not overwater. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Cloud Liveforever is pet-safe. Dudleya nubigena is not individually listed by ASPCA. The Dudleya genus belongs to Crassulaceae but has no documented toxic principles and is not related to toxic genera such as Crassula or Kalanchoe. No toxicity to dogs, cats, or humans is reported. General caution around plant ingestion is always prudent. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.

Cloud Liveforever care — frequently asked questions

What is Cloud Liveforever?

Cloud Liveforever (Dudleya nubigena) is a houseplant with a compact rosette-forming succulent; may produce offsets over time; develops a stout caudex with age growth habit, reaching rosettes 8–15 cm wide; flower stems to 25–40 cm at maturity. Cloud Liveforever is a high-elevation California native Dudleya found on rocky outcrops in the mountains of southern California, often in cloud-influenced, cooler microclimates. It forms silvery glaucous rosettes adapted to cool, moist winters and dry summers.

How much light does cloud liveforever need?

Cloud Liveforever grows best in direct sun (at least 4-6 hours). Requires full, direct sun for 5–7 hours daily, reflecting its exposed mountain habitat. A south-facing outdoor position or large, unobstructed south-facing window indoors is ideal. Shade causes stretched, pale rosettes that are susceptible to rot.

How often should I water cloud liveforever?

Water cloud liveforever every 1–2 weeks in cool season (october–april); completely withheld june–september. Mimic the cool, wet winters and bone-dry summers of its mountain habitat. Water moderately in the growing season, allowing the soil to partially dry between waterings. Cease watering entirely in summer. Cool temperatures during winter watering reduce rot risk. Never water overhead. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is cloud liveforever toxic to cats and dogs?

Cloud Liveforever is pet-safe. Dudleya nubigena is not individually listed by ASPCA. The Dudleya genus belongs to Crassulaceae but has no documented toxic principles and is not related to toxic genera such as Crassula or Kalanchoe. No toxicity to dogs, cats, or humans is reported. General caution around plant ingestion is always prudent.

What USDA hardiness zone does cloud liveforever grow in?

Cloud Liveforever is rated for USDA zone 8-10 and RHS hardiness H3. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
