Lipstick Plant

Aeschynanthus radicans

Updated Mar 29, 2026

Lipstick Plant (Aeschynanthus radicans) is a tropical trailing houseplant with glossy leaves and vivid red flowers, growing best in bright indirect light, airy rich soil, and steady moisture.

About Lipstick Plant

Lipstick Plant is a trailing tropical houseplant grown for its glossy green leaves and its distinctive red tubular flowers. The blooms emerge from dark maroon calyces, which is what gives the plant its familiar “lipstick” look and makes it stand out so clearly in hanging baskets and elevated pots.

Its stems arch and spill naturally, creating a fuller, softer shape as the plant matures. When conditions are good, clusters of flowers appear near the vine tips, adding bright color against the dense green foliage. That combination of trailing growth and repeat blooming is what makes Lipstick Plant so appealing indoors.

Part of its growing character comes from its epiphytic background. Lipstick Plant is not suited to heavy, airless soil or harsh direct sun. It performs much better in warm indoor conditions with filtered light, an airy potting mix, and a routine that keeps moisture steady without letting the roots sit wet.

How to Care for Lipstick Plant

Watering

Water Lipstick Plant moderately so the mix stays evenly moist but never soggy. A good routine is to water thoroughly when the top inch (2–3 cm) of the mix feels dry, then let the excess drain away completely.

This plant dislikes both extremes. If it dries out too much, the leaves can go limp and buds may drop. If the mix stays constantly wet, root rot becomes much more likely. In brighter, warmer months, Lipstick Plant usually needs water more often than it does in cooler, darker periods.

Sunlight

Lipstick Plant grows best in bright, indirect light. It likes strong filtered light rather than harsh direct midday sun, which can scorch the leaves.

An east-facing window is often a very good position, and a bright north-facing spot can also work well. If the light is too weak, flowering drops and the vines may become thin or stretched. The goal is light that feels bright for most of the day without intense sun burning the foliage.

Temperature

Keep Lipstick Plant in a warm, steady range, ideally around 64–77°F (18–25°C). Consistent warmth supports both active growth and more reliable flowering.

Cold drafts, chilly windowsills, and sudden temperature drops can stress the plant. Extended exposure to low temperatures may lead to leaf drop and weaker growth, so it should be protected from cold indoor and outdoor conditions alike.

Humidity

Higher humidity helps Lipstick Plant perform better, especially when it is actively growing or forming buds. It can survive in average indoor air, but growth and flowering usually improve when the air is more comfortably moist.

Bathrooms, kitchens, grouped plants, pebble trays, or a small humidifier can all help. If humidity is raised, keep airflow reasonable and avoid leaving the foliage cold and wet for long periods.

Soil

Use a rich organic mix that still drains well. Lipstick Plant prefers a substrate that holds some moisture and nutrients but also stays airy enough for roots to breathe.

A potting mix amended with bark, perlite, or other chunky materials usually works better than a dense, heavy growing medium. A pot with drainage holes is essential, and a slightly snug container is often safer than an oversized pot that stays wet for too long.

Feeding

Feed Lipstick Plant lightly during spring and summer, about every 4–6 weeks, using a balanced water-soluble houseplant fertilizer diluted to half strength. This supports healthy foliage and flowering without overloading the roots.

In winter or in lower light, reduce or pause feeding because growth slows naturally and unused fertilizer can build up in the potting mix.

Pruning & Grooming

Prune Lipstick Plant lightly after a main bloom cycle to keep it fuller and encourage branching. Cutting back overly long or bare vines just above a pair of leaves often helps stimulate side shoots.

Healthy cuttings can also be rooted to make new plants or to thicken the original pot. Wiping dust from the leaves from time to time helps the foliage stay clean and efficient.

Pests & Problems

Lipstick Plant is not especially difficult, but it can attract mealybugs, aphids, or spider mites, especially in dry indoor air. Most serious problems, however, come from care imbalance rather than pests.

Very dry air and underwatering can cause buds to shrivel or fail to open, while overwatering in a dense mix can lead to yellowing leaves and root decline. Consistent moisture, decent humidity, and strong drainage prevent most recurring issues.
