With its bold red tubular flowers and glossy, dark green leaves flushed with burgundy beneath, Aeschynanthus ‘Hot Flash’ is a showstopping cultivar of the classic Lipstick Plant. Its arching, trailing stems make it ideal for hanging baskets or high shelves, where the vivid blooms can cascade beautifully against the foliage. When given the right light and care, it blooms reliably from spring through autumn.
Scientific Name
Aeschynanthus ‘Hot Flash’ (from Greek aischynē, “shame”, and anthos, “flower” – possibly referring to the bold, almost bashful way the flower emerges from a dark bud)

Common Name(s)
Lipstick Plant, Aeschynanthus ‘Hot Flash’
Origin
Cultivar bred from species native to Southeast Asia, particularly found trailing from tree branches in humid forests
Light
Prefers bright, indirect light. Strong morning light is fine, but avoid harsh midday sun. Too little light may result in fewer blooms and leggier growth.
Water
Water when the top 2–3cm of soil feels dry. Keep lightly moist in the growing season and reduce in winter. Always use room-temperature water and ensure good drainage.
Humidity
Enjoys moderate to high humidity. Mist occasionally or use a pebble tray. Ideal for bright bathrooms or kitchens.
Soil
Use a loose, airy mix – combine peat-free compost with orchid bark and perlite for excellent drainage. Repot every 1–2 years in spring.
Food
Feed every 4–6 weeks in spring and summer with a diluted, high-potassium liquid fertiliser to support flowering.
Temp
Prefers 18–26°C. Avoid cold draughts and protect from temperatures below 15°C.
Pet-safe
Non-toxic – safe for pets and children.
Sprouts Top Tips
To encourage bushier growth and more blooms, pinch back the stems after flowering. Bright light and a snug pot help trigger repeat flowering.
Extras
Flowers often appear in clusters at the ends of stems, bursting from deep maroon buds like a tube of lipstick – hence the name.
Did You Know?
In the wild, Aeschynanthus species often grow as epiphytes, clinging to tree trunks and absorbing moisture from the air – which explains their preference for airy soil and humidity indoors.
