With its cascading vines and delicate pink-speckled leaves, Aeschynanthus radicans 'Pink Polka' brings soft color and tropical flair to any indoor setting. As a cultivar of the classic Lipstick Plant, 'Pink Polka' pairs striking foliage with clusters of coral-pink tubular flowers that emerge throughout the year under the right conditions. Its trailing growth habit makes it ideal for hanging baskets, high shelves, or wall-mounted planters, where it can showcase its vibrant beauty naturally.
Key Features of Aeschynanthus radicans 'Pink Polka'

Foliage: Semi-succulent green leaves featuring soft pink variegation for a subtle, artistic effect.
Flowers: Coral-pink tubular blooms appear in clustered bursts from maroon buds.
Growth Habit: Graceful trailing vines reaching up to 90 cm indoors.
Adaptability: Thrives with minimal maintenance if given consistent warmth, humidity, and light.
Blooming Potential: Can flower multiple times a year with correct conditions and light exposure.

Habitat and Growth Characteristics
While 'Pink Polka' is a cultivated form, it shares lineage with Aeschynanthus radicans, a species native to Southeast Asian rainforests. In the wild, these plants grow epiphytically, clinging to trees where they receive filtered sunlight, high humidity, and excellent airflow. Indoors, 'Pink Polka' mirrors this by thriving in bright, humid, and well-ventilated spaces.

Growth Rate: Moderate to fast under optimal indoor conditions.
Lifespan: Long-lived perennial with proper care and occasional rejuvenation pruning.
Pet Safety: Non-toxic to cats, dogs, and humans.
Air Circulation: Prefers good airflow to prevent fungal issues and promote strong, resilient growth.

Care Instructions for Aeschynanthus radicans 'Pink Polka'

Light: Provide bright, indirect light. Low light fades variegation and reduces flowering. Too much direct sun scorches leaves.
Watering: Water once the top layer of soil feels dry. Avoid waterlogging the soil to prevent root rot.
Humidity: Prefers humidity levels above 50%. Use a humidifier, group plants, or place a humidity tray nearby.
Temperature: Keep between 18–27 °C. Small nighttime drops encourage stronger flowering cycles.
Soil: Use a breathable, well-draining substrate based on orchid bark, perlite, and peat-free potting mix.
Repotting: Every 2–3 years when root-bound. Slight root crowding helps maintain blooming stability.
Fertilizing: Feed every 4–6 weeks with a diluted, balanced liquid fertilizer. Light feeding continues even in winter.
Propagation: Stem cuttings root easily in warm, humid conditions, either in water or light soil mix.
Semi-Hydroponics: Possible using LECA or similar mediums, with gradual acclimation to avoid root shock.
Pruning: Trim back leggy vines and dead foliage to encourage fuller growth and improved flowering.
Placement: Best displayed in hanging planters, wall pots, or elevated locations with steady airflow.
Support: Can be gently trained up a small trellis or moss pole if desired.

Common Problems and Solutions for Aeschynanthus radicans 'Pink Polka'
→ Yellowing Leaves:
Often a sign of overwatering. Allow the topsoil to dry more thoroughly between waterings and ensure good drainage.
→ Lack of Flowers:
Likely caused by insufficient light or lack of minor temperature fluctuations. Increase exposure to bright, indirect light and encourage cooler nights (around 5 °C lower).
→ Brown Leaf Tips:
Indicative of low humidity. Increase ambient moisture using trays or humidifiers.
→ Soft or Mushy Stems:
Caused by root rot. Check soil, trim damaged roots, and repot into fresh, well-draining mix if necessary.
→ Pest Attacks:
Mealybugs, spider mites, and aphids may appear. Treat with neem oil, insecticidal soap, or introduce beneficial insects.
→ Fungal Problems:
Improve airflow, avoid overhead watering, and maintain clean, dry foliage to prevent issues like mildew.
→ Leaf Curling:
Often due to excessive direct sunlight or underwatering. Adjust placement and watering habits accordingly.
→ Wilting Vines:
Can signal root congestion or dehydration. Inspect root mass and repot if tightly bound.
Extra Care Tips
Aeschynanthus radicans 'Pink Polka' prefers stable conditions with slight seasonal adjustments in watering and temperature to mimic its tropical origins. Regularly rinse leaves with lukewarm water to remove dust and keep foliage vibrant.
