The Aeschynanthus japhrolepsis, commonly known as the Lipstick Plant, is a striking houseplant. Admired for its vibrant, tubular flowers and lush, trailing foliage, its distinctive blooms emerge from dark calyces, resembling a tube of lipstick. Native to tropical Southeast Asia, this perennial thrives in warm, humid environments, often growing as an epiphyte. Its vining habit makes it ideal for hanging baskets, allowing stems to cascade gracefully.
Aeschynanthus Japhrolepsis Care
Light
The Lipstick Plant flourishes in bright, indirect light, mimicking its natural habitat beneath a tropical canopy. An east or north-facing window provides suitable conditions. Avoid direct, harsh sunlight, as it can scorch glossy leaves and hinder flowering. Insufficient light slows growth and reduces blooms. Too much direct sun can also lead to leaf burn and discoloration.
Watering
The Lipstick Plant prefers consistent moisture without becoming waterlogged. Water when the top inch or two of soil feels dry. Avoid allowing the plant to sit in standing water, as this leads to root rot. During the active growing season (spring and summer), increase watering frequency. Reduce watering in fall and winter as growth slows.
Humidity
Originating from humid tropical forests, the Lipstick Plant requires elevated humidity (50-80%) for health and flowering. Increase ambient humidity by placing the plant on a pebble tray, grouping it with other plants, or using a room humidifier. Misting offers temporary relief, but consistent high humidity is more effective. Frequent misting can also lead to foliar fungal issues if leaves remain wet.
Soil
As an epiphyte, the Lipstick Plant requires a well-draining, airy potting mix for root aeration. Heavy, compacted soils that retain too much moisture can cause root rot. An orchid or aroid mix, or a blend of peat moss, perlite, and pine bark, works well. This mimics the loose, organic matter found where these plants naturally grow.
Temperature
A stable temperature range is important for the Lipstick Plant. It performs best in average room temperatures, ideally 65°F to 75°F (18°C to 24°C). Temperatures below 50°F (10°C) can cause stress and leaf drop. Protect the plant from sudden temperature fluctuations and cold drafts, such as those near windows, air conditioning vents, or exterior doors.
Fertilizing
Regular fertilization supports the Lipstick Plant’s growth and encourages flowering. During the active growing season (spring and summer), apply a balanced, water-soluble liquid fertilizer, diluted to half strength, every two to four weeks. Reduce or cease fertilizing in fall and winter when growth slows. Over-fertilization can result in a buildup of salts, harming the plant.
Promoting Blooms and Healthy Growth
Pruning
Pruning the Lipstick Plant maintains its shape, encourages bushier growth, and promotes abundant flowers. Prune leggy or straggly stems to encourage new growth. The ideal time for a substantial prune is after its flowering cycle, in late summer or early fall. Use clean, sharp shears to make cuts just above a leaf node to stimulate branching.
Repotting
Repotting is needed when the Lipstick Plant becomes root-bound, indicated by roots growing out of drainage holes or faster drying soil. This occurs every one to three years, depending on growth rate. Early spring or after the main bloom season are suitable times. Select a pot one to two inches larger than the current one and use fresh, well-draining soil mix.
Propagating Aeschynanthus Japhrolepsis
Propagating the Lipstick Plant is straightforward using stem cuttings. Take healthy stem sections, about 4-6 inches long, without blooms. Remove leaves from the bottom inch or two to expose nodes. Place cuttings in water or a moist, well-draining rooting medium like perlite and peat. High humidity, such as covering with a plastic bag, aids rooting, which takes a few weeks.
Troubleshooting Common Problems
Common issues affecting the Lipstick Plant often signal environmental imbalances. Yellowing leaves indicate overwatering, underwatering, or insufficient light. Browning leaf edges point to low humidity or infrequent watering. Leaf drop can be a symptom of stress from sudden temperature changes or inconsistent watering.
Root rot, characterized by mushy, dark roots and wilting foliage, is caused by overwatering and poor drainage. Address this by improving soil aeration and adjusting watering habits. The Lipstick Plant can encounter spider mites, mealybugs, or aphids. Regular inspection and prompt treatment with insecticidal soap or neem oil manage these infestations.
Is Aeschynanthus Japhrolepsis Pet Safe?
The Aeschynanthus japhrolepsis, or Lipstick Plant, is non-toxic to common household pets. This makes it a safe choice for homes with animals.
