The Lipstick Bush, Aeschynanthus radicans, is a captivating houseplant known for its vibrant blossoms. Its common name comes from its brightly colored, tubular flowers emerging from dark calyces, resembling a tube of lipstick. This striking appearance makes it a popular choice for indoor gardeners.
Understanding Your Lipstick Bush
Native to humid, tropical Southeast Asia, the Lipstick Bush naturally grows as an epiphyte or lithophyte, anchoring itself to other plants or rocks rather than soil. It develops long, trailing vines with waxy, dark green leaves. Its distinctive scarlet red, tubular flowers cascade beautifully, making it an excellent choice for hanging baskets.
Comprehensive Care Guide
Light
Lipstick Bushes thrive in bright, indirect light, mimicking its natural habitat. Placing the plant near an east or west-facing window is ideal, providing ample light without harsh direct exposure. Too much direct sun scorches leaves, while insufficient light causes leggy growth, leaf drop, or lack of blooms.
Watering
These plants prefer consistent moisture but are susceptible to root rot if overwatered. Water thoroughly when the top 1 to 2 inches of soil feel dry. Ensure excess water drains completely, as standing water harms roots. Reduce watering frequency during cooler winter months when growth slows.
Humidity and Temperature
As a tropical species, the Lipstick Bush appreciates high humidity (50-70%). Increase humidity by placing the plant on a pebble tray, using a room humidifier, or grouping it with other plants. Misting can help, but do it in the morning to allow leaves to dry and prevent fungal issues. It flourishes in average indoor temperatures (65-75°F / 18-24°C). Avoid sudden temperature drops, cold drafts, or air conditioning vents, as these stress the plant and cause leaf drop.
Soil and Fertilizing
A well-draining, airy potting mix is essential, reflecting its epiphytic nature. A blend including perlite, sand, orchid bark, or sphagnum moss promotes good aeration and drainage. During the active growing season (spring through summer), fertilize every two to four weeks with a balanced liquid fertilizer diluted to half strength. Reduce or cease fertilization during fall and winter when growth slows.
Pruning
Pruning maintains shape, encourages bushier growth, and promotes abundant flowering. Prune after the main flowering period. Use clean, sharp shears to cut just above a leaf node, where new growth emerges. Regular removal of leggy or straggly stems keeps the plant tidy and healthy.
Propagating Lipstick Bush
Propagating Lipstick Bush is straightforward, primarily through stem cuttings. Select healthy, non-flowering stems 4 to 6 inches long with at least two or three leaf nodes. Remove lower leaves to expose nodes where new roots form.
Cuttings root in water or a moist, well-draining potting mix. For soil, a mix of perlite and vermiculite or standard potting mix with added perlite works well.
Maintain a warm, humid environment, perhaps by covering the pot with a plastic bag or using a propagation dome. Roots typically develop within two to eight weeks, then new plants can be potted individually.
Troubleshooting Common Problems
Yellowing or browning leaves often indicate watering issues (too much or too little) or insufficient humidity. Overwatering causes root rot, leading to yellow, wilted leaves, while underwatering results in dry, crispy leaves. Adjusting watering to allow topsoil to dry between waterings and increasing humidity can alleviate these symptoms.
Lack of blooms is commonly due to insufficient light, as the Lipstick Bush requires bright, indirect conditions to flower. Incorrect fertilization (e.g., too much nitrogen promoting foliage over flowers, or lack of phosphorus) can also prevent blooming. Ensuring adequate, balanced nutrients and sufficient light encourages flowering.
While generally resilient, Lipstick Bushes can encounter pests like spider mites, mealybugs, and aphids. Inspect regularly for signs of infestation, such as webbing, cottony masses, or sticky residue. Small infestations can be managed by rinsing with water; persistent issues may require insecticidal soap or neem oil.
