How to Grow West Indian Sundew
West Indian Sundew
Drosera intermedia subsp. intermedia
flowerThe West Indian Sundew is a carnivorous plant featuring rosettes of small leaves covered in sticky, gland-tipped tentacles that trap and digest insects.

Establishment
4-6 weeksYoung plant developing its first rosette of leaves with small glandular tentacles beginning to form
Keep in high humidity under bright light; maintain consistent moisture; avoid fertilizer and nutrients
Vegetative Growth
2-4 monthsRosette expands with increasingly larger leaves covered in prominent red or pink mucilaginous tentacles for trapping insects
Maintain high humidity and bright light; allow the plant to trap insects naturally; do not feed artificially; water with distilled water only
Flowering
3-4 weeksSlender flower stalks emerge from the center of the rosette bearing small white, pink, or red delicate flowers arranged in a raceme
Ensure adequate light to support flowering; maintain consistent moisture; allow natural pollination by insects if possible
Seed Development
4-6 weeksFlowers fade and seed pods develop, containing numerous tiny seeds that will mature and dry
Continue consistent care; allow seeds to mature fully before harvesting; seeds require cold stratification for germination
Dormancy (Optional)
2-3 months (winter)Plant may slow growth or enter dormancy in winter, particularly in cooler zones; some leaf die-back is normal
Reduce watering slightly but keep soil moist; provide cooler temperatures (50-60°F) if possible; bright light is still important

Common Pests
-
Increase humidity; mist regularly with distilled water; isolate affected plants; rarely requires intervention as sundews trap many pests
-
Improve air circulation; reduce humidity slightly if severe; ensure water is distilled; use fungicide only as last resort with non-toxic options
-
Remove with cotton swab dipped in distilled water; isolate plant; rarely problematic due to plant's carnivorous nature
Uses
Natural Insect Control
HouseholdWest Indian Sundew naturally traps and digests flying insects including flies, gnats, and small mosquitoes, making it an effective biological pest control for indoor spaces and greenhouses. A single plant can capture dozens of insects weekly. [source]
Pollinator Garden Addition
WildlifeThe delicate flowers attract small pollinators and the sticky leaves provide an interesting feeding mechanism that benefits ecosystem understanding. The plant supports bog habitat ecology. [source]
Terrarium Showpiece
CraftWest Indian Sundew is a centerpiece carnivorous plant for specialized terrarium displays, particularly in closed or high-humidity terrariums where its delicate tentacles and flowers create visual interest. Popular with plant collectors and in botanical displays. [source]
Traditional Herbal Uses
MedicinalHistorically used in traditional medicine by Caribbean and indigenous peoples for respiratory conditions and cough relief, though modern scientific evidence is limited. Some species of Drosera are studied for bronchitis treatment. [source]
Ornamental Botanical Interest
CulinaryWhile not culinary in the traditional sense, the plant represents the botanical wonder of carnivorous adaptations and is cultivated for educational purposes in botanical gardens and specialized grower collections worldwide. [source]

Harvest Tips
Harvest mature seeds by carefully collecting dried seed pods; seeds can be sown immediately on moist sphagnum moss or stratified in refrigerator for 4-6 weeks before sowing; do not harvest leaves or disturb the plant for propagation; allow the plant to self-propagate through natural seed dispersal
Fun Facts
- 🌱 West Indian Sundew's sticky tentacles can exert surprising strength, with the viscous mucus holding prey items up to three times the plant's own weight, slowly folding the leaves inward to digest the insect over several days.
- 🌱 The plant's glandular tentacles serve a dual purpose: outer tentacles trap insects while inner tentacles digest them using enzymes similar to those found in animal stomachs, making it one of nature's most efficient hunters in nutrient-poor bogs.
- 🌱 Sundews are among the fastest-moving plants in the world; when an insect is caught, some tentacles can move toward it in just minutes, a remarkable response in the plant kingdom that fascinated Charles Darwin who studied carnivorous plants extensively.
