What Is a Curly Lipstick Plant? 🌺
Overview and Origins 🗺️
The curly lipstick plant belongs to the Gesneriaceae family, a close relative of African violets and gloxinias. Native to the humid rainforests of Southeast Asia (including Malaysia, Java, and Indonesia), it grows as an epiphyte—perching on trees and absorbing moisture and nutrients from the air and rain. This natural habit explains why it thrives in bright, humid indoor environments but dislikes soggy soil.
Its common name comes from the unique flower buds: dark maroon calyces that resemble lipstick tubes, from which bright red (sometimes orange or pink in hybrids) tubular flowers emerge. The “curly” varieties stand out with their tightly spiraled, wavy, or twisted leaves, giving the plant a fun, textured appearance that’s perfect for modern interiors.
In cultivation, curly lipstick plants can trail up to 2-3 feet, making them ideal for hanging baskets or shelves. With proper care, they bloom profusely from late summer through fall, and often sporadically year-round in optimal conditions.
Curly vs. Regular Lipstick Plant: Key Differences 🔍
While both are cultivars of Aeschynanthus radicans (or sometimes Aeschynanthus lobbianus hybrids), the curly versions offer distinct appeal:
- Foliage: Standard lipstick plants have flat, glossy, pointed oval leaves. Curly types (‘Curly’, ‘Rasta’, ‘Twister’) feature leaves that curl tightly inward, creating a bushier, more compact look with a whimsical twist.
- Growth Habit: Curlies tend to be denser and less prone to legginess, though both trail elegantly.
- Flowering: Blooms are similar—vibrant red tubes—but curlies often produce more flowers when happy, thanks to their vigorous growth.
- Care Needs: Identical overall, but the curly leaf structure can make them slightly more forgiving of lower humidity, as the curls help retain moisture.
Many growers prefer curlies for their unique texture, which adds visual interest even when not in bloom.
Ideal Growing Conditions ☀️💧
Mastering the environment is key to a healthy curly lipstick plant. These tropical beauties mimic rainforest conditions: bright filtered light, warm temperatures, and high humidity.
Light Requirements 🌞
Bright, indirect light is non-negotiable for lush growth and blooming. Direct sunlight scorches the delicate leaves, causing brown crispy edges, while low light leads to stretched, leggy stems and zero flowers.
- Best locations: East-facing window for gentle morning sun, or 2-4 feet from a south- or west-facing window with sheer curtains.
- Signs of insufficient light: Pale leaves, slow growth, no buds.
- Signs of too much light: Bleached or burned foliage.
In darker homes or winter months, supplement with full-spectrum LED grow lights (6500K) for 12-14 hours daily. I’ve seen dramatic improvements in bloom production with this simple addition—plants that barely flowered suddenly covered in buds!
Expert Tip: Rotate your plant every few weeks for even growth and to prevent leaning toward the light source. 💡
Temperature and Humidity 🌡️😌
Curly lipstick plants prefer consistency:
- Daytime temperatures: 70-80°F (21-27°C) for optimal growth.
- Nighttime: No lower than 60°F (15°C)—cold drafts from windows or doors can cause bud drop or leaf loss.
- Humidity: 50-70% ideal. Below 40% leads to brown leaf tips and reduced blooming.
To boost humidity:
- Use a pebble tray filled with water (pot elevated above water line).
- Group with other plants for a microclimate.
- Run a humidifier nearby, especially in winter with dry heating.
- Mist lightly in mornings, but avoid wetting flowers to prevent rot.
In my experience, bathroom or kitchen placements work wonders due to natural steam, as long as light is adequate.
Soil and Potting Mix 🪴
As epiphytes, curly lipstick plants detest heavy, water-retentive soil. Root rot is the #1 killer!
- Ideal mix: Chunky, well-aerating for fast drainage and airflow.
- DIY recipe: 40% orchid bark, 30% peat-based potting soil or coco coir, 20% perlite, 10% charcoal (for sweetness and disease prevention).
- Commercial alternatives: Aroid mix, African violet mix lightened with perlite, or orchid potting medium.
- pH: Slightly acidic, 6.0-6.5.
Use pots with drainage holes—terracotta is excellent for wicking excess moisture. Avoid pure potting soil, which compacts and suffocates roots.

Watering and Feeding 💦🍽️
Getting watering right prevents most issues with curly lipstick plants.
Watering Schedule 🚰
These plants like to dry out slightly between waterings—overwatering is far more dangerous than underwatering.
- Rule of thumb: Water thoroughly when the top 2-3 inches of soil feel dry (usually every 7-10 days in summer, 10-14 in winter).
- Method: Soak until water runs out the bottom, then empty the saucer to avoid sitting water.
- Water quality: Room-temperature rainwater or distilled; tap water is fine if allowed to sit overnight to off-gas chlorine.
- Seasonal adjustments: Reduce in low-light winter months to prevent rot.
Signs to watch:
- Wrinkled or shriveled leaves: Underwatered—water immediately.
- Yellowing lower leaves or mushy stems: Overwatered—let dry out and check roots.
Pro insight: Use a moisture meter for precision if you’re unsure. In humid environments, err on the dry side.
Fertilizing for Blooms 🌸
Feeding fuels growth and flowering, but too much causes salt buildup and leaf burn.
- Active season (spring-summer): Fertilize every 2-4 weeks with diluted balanced liquid fertilizer (e.g., 20-20-20 at 1/4-1/2 strength).
- Bloom boost: Switch to high-phosphorus formula (e.g., 10-30-20) 4-6 weeks before expected flowering (late spring).
- Fall-winter: Monthly or none, as growth slows.
Always fertilize on moist soil to avoid root burn. Organic options like fish emulsion or seaweed extract work well for natural feeding.
Pro Tip Box: Curly lipstick plants bloom better when slightly pot-bound—over-fertilizing young plants delays maturity. Let them establish first! 🔒

Pruning, Repotting, and Maintenance ✂️
Regular maintenance keeps your curly lipstick plant compact and floriferous.
Pruning for Bushiness 🌿
Without pruning, plants can become long and sparse.
- When: After flowering or in early spring.
- How: Cut back leggy stems by 1/3-1/2, just above a leaf node. Pinch growing tips regularly for branching.
- Benefits: Encourages fuller growth and more bloom sites.
Use clean, sharp scissors—disinfect with alcohol to prevent disease spread.
Repotting Schedule 🔄
Repot sparingly—every 2-3 years or when roots fill the pot (visible circling or emerging from drainage holes).
- Best time: Spring, at the start of growth.
- Size: Only 1-2 inches larger; tight pots promote blooming.
- Process: Gently tease out old mix, trim any black/rotten roots, and refresh with new aerated mix.
Seasonal Care Adjustments ❄️☀️
- Summer: Increase water/fertilizer; move to shaded patio for humidity boost (bring indoors before nights dip below 60°F).
- Winter: Cut back watering, boost light/humidity, avoid fertilizing heavily.
Consistent care prevents common winter woes like leaf drop.

Encouraging Thriving Blooms 💐
The ultimate reward: those stunning red flowers!
Why Isn’t My Plant Blooming? 😩
Common reasons:
- Insufficient bright light.
- Cool temperatures during bud formation.
- Overwatering or poor drainage.
- Young/im mature plant (takes 1-2 years to bloom reliably).
- Nutrient imbalance (too much nitrogen promotes leaves over flowers).
Expert Tips for Abundant Flowers
- Maximize indirect light year-round.
- Maintain warmth (above 70°F) when buds form.
- Use bloom-booster fertilizer.
- Allow mild stress: Keep slightly root-bound and let soil dry more between waterings.
- Deadhead spent flowers to encourage more.
With these, expect heavy blooms in late summer/fall, often extending into winter with grow lights.
