The Lipstick Plant (Aeschynanthus radicans) is a cherished houseplant admired for its glossy foliage and distinctive, vibrant flowers. Its unique blooms emerge from dark calyces, resembling a tube of lipstick. With trailing vines and striking blossoms, it adds a tropical flair to indoor spaces.
Understanding Lipstick Plant Blooming Cycles
Lipstick Plants typically bloom intermittently from spring through fall, with peak flowering during the warmer months. They can produce flowers multiple times a year under optimal conditions, with the most prolific display during this period. The tubular, bright red flowers emerge from dark maroon calyces, giving them their characteristic “lipstick” appearance.
Individual blooms last several days to about a week, contributing to an extended overall bloom season. With consistent care, a Lipstick Plant can provide continuous flowering for many weeks, making them a rewarding addition to any indoor plant collection.
Optimizing Conditions for Blooms
Bright, indirect light is a primary factor in encouraging a Lipstick Plant to flower. Place the plant near an east or west-facing window for filtered sunlight; too little light hinders bloom production, while direct sunlight can scorch leaves.
Consistent soil moisture is beneficial, but avoid overwatering. Water when the top inch of soil feels dry, ensuring good drainage. High humidity, ideally 60% to 80%, also promotes blooming. A pebble tray, room humidifier, or grouping plants can help achieve these conditions.
Lipstick Plants thrive in temperatures from 65°F to 75°F (18°C to 24°C). This warm environment is conducive to flowering, as sudden drops below 50°F or cold drafts stress the plant. Regular fertilization during the growing season supports bloom development. A balanced, water-soluble fertilizer, diluted to half strength and applied every two to four weeks, is recommended. A slightly cooler, drier rest period in winter can encourage a more robust spring bloom. Allowing the plant to be slightly root-bound may also contribute to increased flowering.
Addressing Non-Blooming Issues
Insufficient light is a common reason a Lipstick Plant may not bloom. Without enough bright, indirect light, the plant prioritizes foliage growth over flower production, often resulting in leggy stems and pale leaves. Moving the plant to a brighter location can often resolve this issue.
Improper watering practices also prevent flowering. Both excessive watering, which can lead to root rot, and prolonged drought stress the plant and inhibit blooms. Dry air from low humidity can also cause flower buds to drop.
Nutrient deficiencies, particularly a lack of phosphorus, impede the blooming process. Conversely, over-fertilization creates salt buildup in the soil, detrimental to the plant’s health and ability to flower. Environmental stressors like sudden temperature changes, cold drafts, or frequent relocation can also deter blossoms.
