Clivia plants, also known as Natal lilies or bush lilies, are native to South Africa and belong to the Amaryllidaceae family. These evergreen perennials are prized for their striking orange, yellow, or red trumpet-shaped flowers and dark green, strap-like leaves. When grown indoors in the U.S., Clivias thrive in conditions that mimic their natural habitat—shaded forest floors with moderate humidity and well-draining soil.
Clivia plants prefer bright, indirect light but can tolerate lower light conditions. Avoid direct sunlight, especially during the harsh midday hours, as it can scorch the leaves. In the U.S., placing them near an east- or north-facing window is ideal. If natural light is insufficient, supplement with fluorescent or LED grow lights to ensure healthy growth and flowering.
Clivias thrive in temperatures between 60°F and 75°F (15°C–24°C). They can tolerate brief drops to 50°F (10°C) but are sensitive to frost. Maintain consistent indoor temperatures and avoid placing them near drafts, heating vents, or air conditioners. Moderate humidity (40–50%) is sufficient, but in dry climates, use a humidifier or place the pot on a tray of pebbles filled with water to increase moisture levels.
Water Clivia plants thoroughly when the top inch of soil feels dry, typically every 1–2 weeks. Reduce watering in winter (every 3–4 weeks) to mimic their natural dormancy period. Overwatering can lead to root rot, so ensure the pot has drainage holes. Use lukewarm water to avoid shocking the roots, and always empty the saucer beneath the pot to prevent waterlogging.
Plant Clivias in a well-draining, peat-based potting mix with added perlite or sand to improve aeration. A slightly acidic to neutral pH (6.0–7.0) is ideal. Fertilize monthly during the growing season (spring to early fall) with a balanced, water-soluble fertilizer diluted to half strength. Avoid fertilizing in winter when the plant is dormant.
Clivias prefer to be slightly root-bound, so repot every 3–4 years or when roots outgrow the container. Use a pot only 1–2 inches larger than the current one. Propagate by dividing offsets (pups) during repotting, ensuring each division has roots attached. Allow cut surfaces to dry for a day before replanting to prevent rot.
To promote flowering, provide a cool (50–55°F or 10–13°C), dry rest period for 6–8 weeks in late fall or early winter. Reduce watering and withhold fertilizer during this time. Return the plant to its usual care routine afterward, and buds should appear in late winter or early spring. Insufficient light or over-fertilization can inhibit blooming.
Clivias are relatively pest-resistant but may occasionally attract mealybugs, scale, or spider mites. Treat infestations with insecticidal soap or neem oil. Yellowing leaves often indicate overwatering, while brown leaf tips suggest low humidity or fluoride in tap water. Use filtered water if necessary.
In spring and summer, focus on active growth by maintaining consistent moisture and fertilizing. In fall, prepare for dormancy by reducing water and fertilizer. During winter, keep the plant cool and dry to trigger blooming. Adjust care based on your specific U.S. climate zone, as indoor conditions may vary.
