The Colibri plant, known for its striking blooms and trailing habit, is a popular choice for indoor gardens and hanging baskets. Its vibrant flowers and distinctive appearance bring a touch of tropical beauty to any home.
Understanding the Colibri Plant
The plant often referred to as the Colibri plant is scientifically classified under the genus Columnea, belonging to the Gesneriaceae family. While “Colibri plant” might imply a hummingbird connection, Columnea is widely known as the “Goldfish Plant”. This popular name comes from its tubular flowers, which distinctly resemble small, brightly colored goldfish seemingly leaping from the foliage.
These plants originate from the tropical Americas and the Caribbean, often growing as epiphytes. Columnea species typically exhibit a trailing or cascading growth habit. Their foliage often presents as dark green, glossy, or hairy leaves arranged along slender stems. The vibrant blooms, commonly orange, red, or yellow, emerge from leaf axils and can persist for weeks or months in favorable conditions.
Colibri Plant Care Guide
Light
Colibri plants thrive in bright, indirect light conditions, mimicking their natural habitat beneath a tree canopy. Placing them near an east-facing window is often ideal, providing gentle morning sun without the harsh intensity of midday or afternoon rays. Direct sunlight can scorch their delicate leaves, leading to damage. If natural light is limited, artificial grow lights can supplement, requiring approximately 14 to 16 hours of daily exposure for optimal growth.
Watering
Consistent moisture is important for Colibri plants, but avoiding waterlogging is equally essential. The soil should remain moist, similar to a squeezed-out sponge, allowing the top inch to dry out between waterings. Overwatering can lead to issues like root rot, while underwatering may cause wilting, drooping leaves, or dry, crispy edges. Using room temperature water is recommended, and if tap water is hard, filtered or rainwater can be beneficial.
Soil
A well-draining, lightweight potting mix is essential for Colibri plants. As epiphytes, their roots require good aeration. An ideal blend often includes equal parts peat moss, perlite, and orchid bark, which provides both moisture retention and excellent drainage. A slightly acidic soil with a pH between 6.0 and 6.5 is also preferred.
Temperature and Humidity
Colibri plants prefer warm, stable temperatures, ideally ranging between 65°F and 75°F (18°C and 24°C). They are sensitive to cold drafts and extreme fluctuations, which can cause leaf drop or hinder flowering. Maintaining high humidity levels, ideally between 60-80%, is also beneficial for these tropical plants. Misting the leaves regularly with room temperature water, grouping plants, or using a humidifier can help provide the necessary moisture in the air.
Fertilization
Regular fertilization supports vigorous growth and abundant flowering in Colibri plants. During the active growing season, typically from spring through fall, a balanced, water-soluble fertilizer diluted to half strength can be applied every two to four weeks. Fertilizers with NPK ratios like 10-10-10 or 20-20-20 are suitable. During winter months, when growth naturally slows, reduce or stop fertilization to allow the plant to rest.
Propagation and Common Issues
Propagating Colibri plants is straightforward, commonly achieved through stem cuttings. Healthy stem segments, typically 4-6 inches long with a few sets of leaves, can be taken just below a leaf node. After removing lower leaves, these cuttings can be planted in a well-draining rooting medium like a peat moss and perlite blend, or even rooted in water. Maintaining warmth and high humidity helps roots develop within a few weeks.
Colibri plants can encounter some common issues. Pests such as spider mites, aphids, and mealybugs can appear, often mitigated by regular inspection and prompt treatment with insecticidal soap. Fungal diseases like root rot or botrytis blight can arise from overwatering or poor air circulation, highlighting the importance of proper drainage and ventilation. Curling leaves or flower loss might indicate insufficient watering, low humidity, or temperature extremes.
