Lipstick Plant Care (Aeschynanthus)

What Is a Lipstick Plant?

Lipstick plants (Aeschynanthus) are tropical epiphytes from Southeast Asia that naturally grow perched on tree branches in humid rainforests. The common name comes from their remarkable flowers: bright red tubes that emerge from dark, tubular calyxes, looking exactly like miniature lipstick tubes extending from their cases.

Several varieties are popular in cultivation. The standard Aeschynanthus radicans has glossy green leaves and classic red flowers. The Black Pagoda (A. longicaulis) features mottled leaf patterns and orange-green flowers. The Twistedor "Rasta" variety has uniquely curled leaves that spiral along the vine, creating a textural showpiece even without flowers.

Light: The Bloom Trigger

Bright indirect light is the single most important factor for getting lipstick plants to bloom. In their natural habitat, they grow in the dappled canopy light of tropical forests — bright but never in harsh direct sun.

An east-facing window is ideal: consistent morning light without the intensity of afternoon sun. South or west windows work if filtered through a sheer curtain. If the plant produces lush foliage but no flowers, it almost certainly needs more light.

Black pagoda lipstick plant care is slightly more forgiving with light — this variety tolerates medium light better than the red-flowering standard, though brighter conditions still produce better results. For guidance on light levels, see our lighting guide.

Watering and Soil

As epiphytes, lipstick plants are accustomed to quick-draining conditions — their roots grab onto tree bark in nature, never sitting in waterlogged soil. This means the potting mix matters as much as the watering frequency.

Use a light, chunky mix: roughly equal parts orchid bark, perlite, and peat moss. Standard potting soil is too dense and water-retentive. In this airy mix, water when the top inch feels dry — typically every 5-7 days in summer, every 10-14 days in winter.

Humidity matters too. At 50-60%, the plant thrives. Below 40%, leaf tips brown and buds may drop before opening. A pebble tray beneath the hanging basket or occasional misting helps — though for the twisted lipstick plant variety, avoid misting directly as water can pool in the curled leaves.

Getting Your Lipstick Plant to Flower

Beyond bright light, lipstick plants benefit from a cool rest period in winter to trigger flower bud development. Reduce temperatures to 60-65°F for 4-6 weeks, cut back watering, and stop fertilizing. This mimics the cooler dry season in their native habitat.

When you resume warmth and regular watering in spring, the plant responds with a flush of buds. Feed monthly during the growing season with a balanced liquid fertilizer — or better, one formulated for blooming plants (higher phosphorus ratio like 10-30-20).

Deadhead spent flowers by pinching off the faded calyx and stem. This keeps energy directed toward new growth and may encourage additional bloom cycles throughout summer and fall.

Common Mistakes to Avoid

• ✗Using heavy potting soil. Lipstick plants are epiphytes — their roots need air. Dense, water-retentive soil causes root rot. Use an orchid-type mix.
• ✗Keeping in low light and expecting flowers. Bright indirect light is non-negotiable for blooming. No light = no flowers, period. Foliage may grow fine, but blooms won't appear.
• ✗Skipping the winter rest. Without a cool period, lipstick plants often refuse to set buds for the next season. Even a few degrees cooler helps.
• ✗Misting twisted/curly varieties excessively. Water trapped in the curled leaves can encourage fungal growth. Use a humidifier or pebble tray instead.
• ✗Not pruning leggy vines. After blooming, trim back long stems by a third to encourage bushier growth and more flowering points for the next cycle.
