Aeschynanthus pulcher

Aeschynanthus pulcher

Aeschynanthus pulcher is a species lipstick plant with glossy green leaves, trailing to climbing stems and bright tubular flowers. Mature plants can produce red blooms with yellow throats, held at the tips of the stems.

The species grows naturally as an epiphyte or lithophyte, so indoor care should keep the roots airy and the plant warm. It likes moisture during active growth, with drainage fast enough to keep the root zone oxygenated.

Flowering features of Aeschynanthus pulcher

• Plant type: Evergreen trailing to climbing lipstick plant.
• Stems: Aerial-rooting stems that can trail from a pot or be guided lightly.
• Leaves: Glossy oval dark green leaves with a firm texture.
• Flowers: Red tubular blooms with yellow throats on mature, well-lit plants.
• Native range: Native to southern Indo-China and western Malesia.
• Root habit: Epiphytic and lithophytic growth means the roots need air and drainage.
• Light: Bright filtered light is important for dense stems and bud formation.

Red flowers of Aeschynanthus pulcher

Aeschynanthus pulcher is native to wet tropical regions where it grows on trees or rocks. In a pot, that means chunky substrate, warm roots and watering that drains away quickly.

The tubular red blooms emerge from darker calyx structures, creating the lipstick-plant flower shape associated with the genus. Strong filtered light and mature stems give the plant the best chance of flowering indoors.

Care for Aeschynanthus pulcher

• Light: Give bright filtered light; too little light usually means sparse growth and fewer flowers.
• Water: Water well during active growth, then let the upper substrate dry before the next watering.
• Humidity: Moderate to higher humidity helps reduce leaf drop and bud stress.
• Temperature: Keep warm and protect from cold draughts.
• Soil: Use a chunky epiphyte-style mix with bark, fibre and mineral drainage.
• Repotting: Repot when roots fill the pot; avoid moving into a much larger container too early.
• Fertilising: Feed lightly during active growth with a diluted balanced fertiliser.
• Pruning: Trim long stems to keep the plant branching and to remove tired growth.
• Propagation: Stem cuttings root well in warm, lightly moist conditions.
• Semi-hydroponics: Can be trialled with warm roots and airy mineral substrate, but stagnant water around stems can cause rot.

Flower and stem issues in Aeschynanthus pulcher

• Few flowers: Usually linked to low light, immature growth or repeated stress.
• Bud drop: Can follow cold draughts, drought stress or sudden watering changes.
• Yellow leaves: Check for wet roots, especially in a dense mix.
• Leaf drop: Often follows cold exposure or long dry periods.
• Pests: Watch for mealybugs, aphids and mites around young shoots and flower buds.

Safety for Aeschynanthus pulcher

Lipstick plants are generally considered non-toxic houseplants. Keep Aeschynanthus pulcher away from pets that chew foliage or pull trailing stems.

Botanical background of Aeschynanthus pulcher

Aeschynanthus is usually explained from Greek roots linked to blush or shame and flower, referring to the red flowers common in the genus. The species epithet pulcher means beautiful.

The name Aeschynanthus pulcher was published by G.Don in A General History of the Dichlamydeous Plants in 1838.

Aeschynanthus pulcher combines glossy trailing stems, firm green leaves and red tubular flowers in one species lipstick plant.
