Care at a glance

Light

Bright but filtered. Stalked Clivia burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Thrives in bright, dappled shade that mimics its natural forest understorey habitat; avoid direct midday sun, which bleaches and scorches the strap-like leaves. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering stalked clivia: water regularly in spring and summer; reduce significantly in autumn and winter.. 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. Keep compost evenly moist (not wet) during the active growing season. Reduce watering to once every three to four weeks during the cool winter rest to help trigger the following season's flowers.

Soil and pot

Stalked Clivia grows best in free-draining loam-based compost with added leaf mould and coarse grit. A rich but open mix mimics the humus-rich forest floor; ensure the container has ample drainage holes as the thick fleshy roots are highly susceptible to waterlogging. 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

Stalked Clivia sits happiest at around 50–70% humidity and 10–25°C (cool winter rest at 10–14°C) (50–77°F (cool winter rest at 50–57°F)). Prefers the higher humidity of its forest origin; in dry indoor environments place the pot on a tray of damp pebbles or use a room humidifier, especially in winter when central heating is running. If you keep the room above 10–25°C (cool winter rest at 10–14°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 stalked clivia sparingly. Feed with a balanced liquid fertiliser every two weeks during the growing season (spring through early autumn); withhold fertiliser during the winter rest period. 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 stalked clivia in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Scale insectsBrown, shell-like scales attach to the undersides of leaves and along the stem; scrape off with a soft brush, then treat with a systemic insecticide or neem-oil spray; check monthly during the growing season.
  • Failure to bloomSkipping the cool, dry winter rest is the primary cause; ensure at least six weeks at 10–14°C with reduced watering before returning the plant to warmth in early spring.

Propagation

Remove offsets from the base of the stem in spring, ensuring each has roots attached, and pot into a gritty, free-draining mix. Seeds can be sown fresh immediately after harvest in moist compost at 20°C; seedlings take 3–5 years to reach flowering size. 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

Stalked Clivia is toxic to pets. Toxic to cats and dogs; the ASPCA lists the genus Clivia under 'Clivia Lily' as toxic to both species. The toxic principle is lycorine and related Amaryllidaceae alkaloids, with the rhizome and stem base containing the highest concentrations. Symptoms include vomiting, salivation, diarrhoea, and with heavy ingestion, low blood pressure, tremors, and cardiac arrhythmias. 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.

Stalked Clivia care — frequently asked questions

What is the common name for Clivia caulescens?

Clivia caulescens is most commonly called Stalked Clivia, but it is also known as Stalked Clivia, Climbing Clivia, Forest Lily. The names refer to the same species, so care instructions for Stalked Clivia apply identically to anything sold as Climbing Clivia.

How much light does stalked clivia need?

Stalked Clivia grows best in bright indirect light (just back from a sunny window). Thrives in bright, dappled shade that mimics its natural forest understorey habitat; avoid direct midday sun, which bleaches and scorches the strap-like leaves.

How often should I water stalked clivia?

Water stalked clivia water regularly in spring and summer; reduce significantly in autumn and winter.. Keep compost evenly moist (not wet) during the active growing season. Reduce watering to once every three to four weeks during the cool winter rest to help trigger the following season's flowers. 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 stalked clivia toxic to cats and dogs?

Stalked Clivia is toxic to pets. Toxic to cats and dogs; the ASPCA lists the genus Clivia under 'Clivia Lily' as toxic to both species. The toxic principle is lycorine and related Amaryllidaceae alkaloids, with the rhizome and stem base containing the highest concentrations. Symptoms include vomiting, salivation, diarrhoea, and with heavy ingestion, low blood pressure, tremors, and cardiac arrhythmias.

What USDA hardiness zone does stalked clivia grow in?

Stalked Clivia is rated for USDA zone 9-11 (indoor in most climates) and RHS hardiness H1b. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
