Lance-leaf Sundew
Drosera adelae
flowerDrosera adelae is a carnivorous plant native to Queensland, Australia, characterized by narrow, lance-shaped leaves covered in glistening red tentacles (modified leaf hairs) that trap insects. It is a compact, rosette-forming species that produces delicate pink flowers and relies on insects for supplemental nutrients in nutrient-poor habitats. This species is popular among carnivorous plant enthusiasts for its striking appearance and relatively manageable care requirements.

Seedling
4-6 weeksTiny rosettes with initial 2-4 small leaves; red tentacles beginning to form but not yet sticky
Maintain high humidity (70-80%), consistent moisture, bright indirect light; avoid disturbance; ensure excellent drainage to prevent damping-off
Juvenile Rosette
3-6 monthsExpanding rosette with 8-15 lance-shaped leaves; tentacles becoming fully developed and sticky; plant reaches 2-3 inches in diameter
Maintain warm temperatures (65-75°F), distilled water only, bright indirect light; begin light feeding with tiny insects if desired (plant will catch its own)
Mature Vegetative
6-12 months (maintenance)Fully formed rosette with 20-30 glistening, reddish leaves; dense tentacle coverage creates striking appearance; ready for reproduction
Maintain stable conditions; water with distilled water only; provide 12-14 hours light daily; humidity 50-70%; keep temperatures 60-75°F
Flowering
4-8 weeksDelicate pink flowers emerge on thin stalks above the rosette; flowers are small (0.5 inch) and appear in clusters; blooming occurs in spring/summer
Maintain consistent watering and humidity; do not fertilize; allow natural pollination or hand-pollinate with small brush; flowers last 1-2 days each
Seed Production & Propagation
4-6 weeks seed maturation; propagation ongoingSmall seed pods develop if pollination successful; tiny seeds mature within 4-6 weeks; seeds are viable for 2+ years when stored properly
Allow pods to dry naturally; collect seeds when pods brown; store in cool, dry conditions; propagate by seeds or leaf cuttings for cloning

Common Pests
-
Improve air circulation; allow soil surface to dry slightly between mistings; use sand layer on top of soil; yellow sticky traps; avoid overwatering
-
Increase humidity to 60%+; mist regularly; ensure good air circulation; spray with distilled water if infestation occurs (avoid miticides on carnivorous plants)
-
Remove with soft brush and distilled water; isolate affected plant; spray with diluted neem oil (use cautiously on carnivorous plants)
-
Remove manually with soft brush; improve air circulation; isolate plant; spray with distilled water or neem oil solution if necessary
-
Spray with distilled water; increase humidity and air circulation; remove heavily infested leaves; plant naturally catches many aphids
Uses
Natural Insect Control
WildlifeDrosera adelae is a carnivorous plant that feeds on small insects including gnats, flies, and mosquitoes, making it useful for biological pest management in indoor growing spaces and terrariums. The sticky tentacles passively trap insects without requiring any action from the grower. [source]
Ornamental Terrarium Plant
HouseholdThe striking red, glistening leaves and delicate pink flowers make D. adelae an attractive specimen for specialized terrariums, plant collections, and display vivariums. Its compact size makes it ideal for closed or open terrariums with controlled humidity. [source]
Specialized Plant Collecting
CraftD. adelae is a popular species among carnivorous plant enthusiasts and collectors, valued for its unique appearance and the challenge of providing proper care. It serves as an engaging entry point into carnivorous plant cultivation. [source]
Traditional Ethnobotanical Interest
MedicinalSome Drosera species have been used in traditional and homeopathic medicine for respiratory conditions, though scientific evidence is limited. D. adelae is primarily ornamental and not typically used medicinally. [source]

Harvest Tips
This is not a harvested plant for consumption. Collect seeds after flowers fade and seed pods brown (typically 4-6 weeks post-flowering). Harvest seeds by carefully opening dried pods over paper. For vegetative propagation, remove healthy leaves in spring/summer and place on moist peat/sphagnum; new plants develop at leaf base in 2-3 months.
Fun Facts
- 🌱 The tentacles on Drosera adelae's leaves move slowly toward prey after an insect lands, creating a sticky trap that can take 15-30 minutes to fully enclose an insect—a remarkable example of carnivorous plant mechanics.
- 🌱 Drosera adelae is named after Adelaide, Australia, reflecting its Queensland origin; the 'adelae' suffix honors the location where it was discovered.
- 🌱 Sundews are among the fastest-moving plants in the world relative to their size; their tentacles can curve around prey with unexpected agility, despite being carnivorous plants with no nervous system.
