The “Owl Plant,” or Huernia zebrina, also known as the “Lifesaver Plant,” is a captivating succulent. Its unique aesthetic appeal and relatively straightforward care make it a rewarding addition to many indoor plant collections.
Understanding the Owl Plant
Huernia zebrina is identified by its star-shaped flowers, which feature prominent cream and red stripes with a raised, dark red or maroon center. This center resembles a lifesaver candy, giving the plant its common name. The plant has fleshy, four-sided stems that are typically deep green but can turn reddish or purple in brighter light. Native to arid regions of eastern and southern Africa, where they grow under shrubs, these low-growing succulents prefer well-draining conditions and balanced light.
Owl Plant Care
Light
The Owl Plant thrives in bright, indirect light, mimicking its natural environment where it often grows under partial shade. Too much direct sunlight, especially harsh midday sun, can lead to scorching, causing stems to turn reddish or yellow. Conversely, insufficient light can result in weak, stretched growth, known as etiolation, and may inhibit flowering.
Water
A “soak and dry” watering method is essential for Huernia zebrina. Water thoroughly until it drains from the pot, then allow the soil to dry completely before the next watering. Overwatering can lead to stem or root rot. During the active growing season (spring and summer), watering every two to three weeks is often sufficient, varying by conditions. During winter dormancy, reduce watering significantly, often to about once a month.
Soil
Huernia zebrina requires a well-draining potting mix to prevent water retention. A specialized succulent or cactus mix, containing inorganic elements like sand, pumice, or perlite, ensures good aeration and quick evaporation, minimizing root issues. Unglazed pots, such as terracotta, aid evaporation. Shallow pots are also recommended, as the plant’s short roots can experience dieback if soil in a deep pot remains wet during dormancy.
Temperature and Humidity
The Owl Plant prefers warm temperatures, ideally 60°F (15°C) to 80°F (27°C). It tolerates temperatures down to 50°F (10°C) but is sensitive to frost and should be brought indoors. While it can endure temperatures up to 100°F (38°C), it may need shade during the hottest parts of the day. Average household humidity is sufficient, as it prefers low to moderate humidity. High humidity with wet soil increases rot risk.
Fertilizing
Fertilizing can encourage vigorous growth and flowering during the active season. Use a diluted succulent or cactus-specific fertilizer, typically once a month during spring and summer. Avoid high-nitrogen fertilizers and dilute any product to half strength to prevent over-fertilization. Cease fertilizing by late August or before winter dormancy to prevent new growth during reduced activity.
Propagating Owl Plants
Propagating Huernia zebrina is straightforward, often achieved through stem cuttings. Select a healthy, mature stem from the parent plant. Using clean, sharp scissors, cut a portion of the stem. Allow the severed end to dry and form a callus for three to four days; this drying period helps prevent rot once planted.
Once callused, insert the cutting about one inch deep into a pot filled with a well-draining succulent or cactus potting mix. Rooting hormone is not strictly necessary. After planting, avoid watering immediately; wait a few days before a light watering to allow the cutting to settle. Place the pot in bright, indirect light, and water sparingly, letting the soil dry completely between waterings until new growth indicates successful rooting, typically within a few weeks.
Common Problems and Solutions
Root or stem rot is a common problem for Huernia zebrina, primarily caused by overwatering or poorly draining soil. Symptoms include mushy, discolored stems or leaves. The solution involves allowing the soil to dry completely between waterings and using a well-draining mix. If rot is observed, promptly remove affected areas with a sterile blade to prevent further spread.
Pests are infrequent, but mealybugs can appear as small, white, cottony masses. Manual removal, followed by treatment with a houseplant insecticide or diluted rubbing alcohol, can manage infestations. Insufficient light can cause etiolation (stretched, weak growth) or lack of flowering, indicating a need for brighter, indirect light. Too much direct sun can cause stems to turn yellow or reddish-brown, signaling stress and a need for a shadier spot.
