Aeschynanthus (Lipstick Plants)

Aeschynanthus (lipstick plants) - quick care overview

• Growth style: trailing or arching epiphyte that looks best in hanging pots or on high shelves with room to cascade.
• Light needs: bright, indirect light close to a good window; long spells of deep shade or harsh midday sun both reduce flowering.
• Watering rhythm: water when roughly the upper third of the mix has dried; repeated deep drought or permanently wet soil both cause bud drop.
• Substrate & roots: prefers a porous, semi-epiphytic mix with bark and mineral components so roots stay airy, not in compact soil.
• Temperature band: comfortable around 18-25 °C; prolonged cold below the mid-teens with wet mix often leads to leaf loss.
• Pets & people: generally treated as low-risk but still ornamental; discourage chewing.

Aeschynanthus: botanical profile for Lipstick Plants

Aeschynanthus is a genus of evergreen epiphytic and lithophytic perennials in Gesneriaceae, described by William Jack in 1823. The name combines Greek roots often interpreted as “ashamed” and “flower”, referencing intensely coloured corollas that resemble lipstick emerging from a tube. Around 150-180 species are recognised, and several are widely cultivated as hanging Lipstick Plants.

• Order: Lamiales
• Family: Gesneriaceae
• Tribe: Trichosporeae (subtribe Didymocarpinae)
• Genus: Aeschynanthus Jack
• Type species: Aeschynanthus volubilis Jack
• Chromosomes: 2n counts mostly around 28-32, with higher polyploids (2n ≈ 48-96) reported in some taxa

Range & habitat: Native from the eastern Himalayas and southern China through mainland Southeast Asia, Malaysia, Indonesia and the Philippines to New Guinea and the Solomon Islands. Aeschynanthus typically grows as an epiphyte on tree branches or occasionally on rocks in humid lowland to montane rainforest, often in mossy, well-ventilated canopy gaps.

• Life form: Trailing or scrambling evergreen vines and subshrubs, usually epiphytic, sometimes lithophytic.
• Leaf attachment: Opposite, short-petiolate leaves spaced along slender to woody stems, often forming pendulous curtains.
• Leaf size: Mostly small to medium, roughly 3-12 cm long in many species, with species-level variation from tiny to broader foliage.
• Texture & colour: From thin and soft to thick, coriaceous leaves; typically uniform green but sometimes mottled or flushed, with a cuticle that tolerates intermittent drying.
• Notable adaptation: Tubular, brightly coloured corollas positioned at shoot tips or in clusters, well suited to bird pollination in shaded forest canopies.

Inflorescence & fruit: Flowers are produced in terminal or axillary clusters with narrow, tubular corollas in red, orange or yellow tones, often adapted to sunbird visitation. Fruits are elongate, dehiscent capsules that split to release numerous small seeds with hair-like appendages that aid wind dispersal.

Aeschynanthus (Lipstick Plants) - foliage, flowers & indoor care

Why Aeschynanthus deserves a prime hanging spot

Aeschynanthus, usually sold as lipstick plant, earns its hook with glossy leaves and bright tubular flowers that really do look like a lipstick being twisted out of a case. Stems arch and cascade instead of hogging floor space, so one pot can pull a lot of visual weight from a shelf, beam or hanging rail.

It is also refreshingly honest. When conditions are right, new shoots extend, leaf pairs stack neatly and buds cluster at the tips. When something slips, you see droop, bud drop or pale new growth fast. If you like plants that give clear feedback instead of suffering quietly, Aeschynanthus is very much in that camp.

Where Aeschynanthus comes from-and what that means in a pot

Many Aeschynanthus species grow as epiphytes or lithophytes in warm, humid forests of Southeast Asia. Roots anchor into pockets of moss, leaf debris or rock crevices; water arrives often, runs through quickly and air stays humid but moving.

Indoors, aim for the same pattern: bright but filtered light, a springy, well-aerated mix and a watering rhythm that moves between “evenly moist” and “partially dry”, never between swamp and bone-dry. Once that is dialled in, the exact weekday you water becomes far less important.

Light that keeps lipstick plants flowering

Flowering is driven by light. Aeschynanthus wants strong, indirect light close to a good window-east or west aspects, or a position slightly back from a south-facing pane where leaves never feel hot. In that range, vines stay reasonably compact and buds form reliably at the tips.

In weak light you get long, thin stems, wide gaps between leaves and very few flowers. Hard sun through glass goes the other way: bleached patches, crisp margins and buds that dry before opening. If you are unsure where your windows sit on the scale, compare them with the real-world examples in our bright-indirect light article and park Aeschynanthus towards the brighter end of those zones.

Water and substrate-oxygen first, then moisture

A simple baseline: water when the top third of the mix feels dry and the pot is clearly lighter, then water properly. That means soaking the whole rootball until water runs from the drainage holes and letting every drop drain away-no permanent puddles in cachepots.

Repeated deep drought, where mix is dry right through and stems start to wrinkle, triggers bud drop, dull foliage and dieback at the tips. Permanent saturation suffocates roots; you will see yellow leaves on stems emerging from heavy, wet mix and, if you unpot, black mush where roots should be. If you are on the fence, waiting another day is safer than topping up a still-damp pot, especially if you follow the checks in our detailed watering guide.

For substrate, treat Aeschynanthus as a semi-epiphytic vine. Start with a quality indoor mix and cut it with 30-50 % chunky or mineral components such as perlite, pumice, fine orchid bark or expanded clay. When you squeeze a handful it should spring back, not pack into a solid lump.

Temperature, humidity and airflow Aeschynanthus accepts

Indoors, Aeschynanthus is content around 18-25 °C. Short dips a little cooler usually do not matter for healthy plants, but long spells below about 15 °C slow growth and below roughly 12 °C leaf drop and rot become more likely, especially in wet mix. Keep baskets out of cold winter draughts and away from air-con blasts.

Average household humidity keeps leaves going, but buds and flowers are more reliable when air is at least moderately humid. Grouping plants, running a small humidifier nearby or standing pots above damp expanded clay in wide trays all help. What you do not want is stale air: gentle background airflow lets foliage dry after watering and keeps fungal issues down.

Growth rhythm, shaping and feeding

Aeschynanthus grows as a trailing or lightly climbing vine. New shoots extend from the tips and from nodes along older stems, building curtains of foliage in hanging baskets. Left unchecked, centres can thin out; trimming a few of the longest vines back after flowering keeps the plant compact and encourages branching lower down.

Fertiliser is there to support decent light and substrate, not to compensate for poor basics. Use a balanced, diluted liquid fertiliser while you can actually see new leaves and buds forming. Small, regular feeds on already moist mix work far better than strong, occasional doses into dry or waterlogged substrate. If growth has stalled or the plant is coming back from a scare, skip feed and fix light, moisture and root health first.

Aeschynanthus, pets and handling

Lipstick plants are generally listed as non-toxic to humans, cats and dogs, so they are a reasonable option where curious mouths might occasionally investigate foliage. Even so, eating sizeable amounts of any plant can upset a stomach, so it still helps to hang baskets slightly out of reach and avoid play zones.

Sap can be mildly irritating on very sensitive skin. When pruning or repotting, wash hands afterwards and keep fingers away from eyes as a basic precaution.

First weeks with Aeschynanthus after shipping

After transit, Aeschynanthus often turns up with slightly limp vines, a few yellowing older leaves or buds that have dried and dropped. That is a normal reaction to time in a box: dark, fluctuating temperatures and low humidity.

Once unpacked, move the plant straight into its long-term bright, indirect position. Check how far the mix has dried and only water if the top portion is genuinely dry. Skip instant repotting or heavy pruning; let Aeschynanthus stabilise first. For a wider view of what most houseplants do in the first weeks at home, see our acclimatisation guide.

Aeschynanthus troubleshooting-quick pattern reading

• Buds shrivel and drop before opening: usually a mix of deep dryness, cold draughts or being moved while buds form. Keep substrate lightly moist, protect from cold air and avoid relocating the plant once buds are visible.
• Wrinkled, soft leaves and a very light pot: prolonged drought. Soak the root ball thoroughly, let excess drain and tighten your watering rhythm so the top third of the mix is not left bone dry for long.
• Yellow leaves on stems emerging from heavy, wet soil: classic low-oxygen, overwatered roots. Let the mix dry further between waterings, clear drainage holes and consider repotting into a looser, more mineral-rich substrate.
• Long, bare stems with few flowers: light has been low for weeks. Move Aeschynanthus closer to a bright window or under decent LED grow lights so it gets strong, indirect light for most of the day.
• Brown tips or edges on older leaves: often a combination of very dry air, irregular watering or fertiliser salts. Flush the pot with plain water, smooth out your watering routine and nudge humidity up if the room is extremely dry.
