The variegated lipstick plant (Aeschynanthus radicans ‘Variegata’) is a captivating houseplant known for its striking foliage and vibrant, tubular blooms. Its common name comes from the way flower buds emerge from dark bracts, resembling a tube of lipstick. With trailing vines, it is ideal for hanging baskets, showcasing its distinctive leaves and colorful flowers. The unique variegation, often creamy-white or yellow streaks on deep green leaves, adds visual appeal.
Essential Care Requirements
Light
Variegated lipstick plants thrive in bright, indirect light. An east or west-facing window, or a few feet from a south-facing window with diffused light, is ideal. Insufficient light leads to leggy growth and few blooms. Direct, intense sunlight can scorch the delicate variegated foliage, causing browning or a reddish-purple hue. Consistent light maintains healthy growth and the plant’s distinctive coloring.
Water
Watering is fundamental for the variegated lipstick plant, which prefers consistently moist but never soggy soil. Allow the top inch or two of potting mix to dry before watering again. Ensure water drains freely from the pot to prevent root rot. Overwatering leads to yellowing leaves and root issues, while prolonged dryness causes leaves to wilt and drop.
Soil
A well-draining, airy potting mix is crucial for variegated lipstick plants. A suitable blend includes peat moss, perlite, and orchid bark, providing moisture retention and aeration. Heavy, compact soils lead to waterlogging and root rot. Good drainage supports robust root development and and overall plant vigor.
Humidity
These tropical plants flourish in high humidity, ideally between 50-70%. Low humidity causes browning leaf edges, leaf drop, and reduced flowering. To increase moisture, use a pebble tray filled with water beneath the pot, group plants, or employ a room humidifier. Misting offers a temporary boost but is less effective.
Temperature
Variegated lipstick plants prefer warm conditions, ideally between 65-80°F (18-27°C). Stable temperatures are important, as sudden drops or cold drafts stress the plant and lead to leaf loss. While they tolerate temperatures as low as 59°F (15°C) during winter dormancy, consistent warmth promotes continuous growth and flowering. Avoid placing plants near air conditioning vents or drafty windows.
Fertilizer
During the active growing season, feed your variegated lipstick plant monthly with a balanced liquid houseplant fertilizer. This provides nutrients for vigorous foliage growth and abundant flowering. Reduce or cease fertilization during dormant months when the plant’s growth slows. Follow product instructions for dilution to prevent over-fertilization.
Preserving Variegation
The distinct creamy-white or yellow patterns on the leaves are influenced by light intensity and nutrient availability. Insufficient bright, indirect light is a common reason for variegation loss, causing new growth to appear green as the plant maximizes chlorophyll production. Ample filtered light helps ensure variegated patterns remain pronounced.
Nutrient imbalances also impact variegation, so a consistent feeding schedule during the growing season supports healthy leaf development. Extreme conditions or stress can negatively affect leaf patterns. If variegation browns, it may indicate too much direct sun exposure or fluctuating environmental conditions. Adjusting light levels or providing stable temperatures can help restore the plant’s unique coloration.
Repotting and Pruning
Repotting a variegated lipstick plant is typically needed every two to three years, or when it becomes root-bound. This is indicated by roots growing out of drainage holes or the soil drying out quickly. Spring, before the main growth spurt, or after flowering, are suitable times. Choose a new pot only one to two inches larger than the current one, as an excessively large pot can retain too much moisture and lead to root rot. When repotting, gently remove the plant, shake off old soil, and replant in fresh, well-draining potting mix.
Pruning promotes bushier growth, encourages more blooms, and manages vine length. The best time to prune is after flowering or during the active growing season. Make clean cuts using sharp, sterile shears, trimming stems to a desired length. Removing spent flowers stimulates new blooms. Regular pruning maintains an attractive shape and overall plant health.
Troubleshooting Common Issues
Common issues affecting variegated lipstick plants often stem from environmental factors. Yellowing leaves can signal overwatering or underwatering; check soil moisture first. Nutrient deficiencies or root-bound conditions also contribute to yellowing. Adjusting watering and ensuring proper drainage often resolves these concerns.
A lack of blooms is frequently attributed to insufficient light. These plants require bright, indirect light to flower. Moving the plant to a brighter location or supplementing with a grow light can encourage flowering. Incorrect fertilizer application, such as too much nitrogen or insufficient potassium, might also inhibit blooms. Pests like spider mites, mealybugs, and aphids can infest lipstick plants. Inspect the plant regularly and treat infestations with insecticidal soap or neem oil.
