Spoon-leaved Sundew
Drosera intermedia
flowerDrosera intermedia is a small carnivorous plant with distinctive spoon-shaped leaves covered in sticky, glandular hairs that trap and digest insects. This delicate sundew is found in boggy, acidic wetlands across North America and Europe, thriving in nutrient-poor environments where it supplements nitrogen through insect digestion. It produces delicate white to pink flowers on thin stems during summer.

Seed Germination
2-4 weeksTiny seedlings emerge on moist sphagnum moss, appearing as small reddish dots with initial leaf structures visible.
Keep under bright, indirect light with high humidity (use clear dome or bag). Maintain constant moisture. Temperature 65-75°F optimal. Do not fertilize.
Seedling & Rosette Formation
6-12 weeksSmall rosettes of spoon-shaped leaves develop, each leaf bearing sticky red glandular tentacles (trichomes) that glisten.
Maintain high humidity and constant moisture. Provide bright light. Begin dormancy period in winter if grown outdoors (zone-dependent).
Vegetative Growth
2-4 monthsMature rosette expands with 1-3 inch diameter leaf clusters. Leaves become increasingly efficient at trapping insects.
Continue high humidity and distilled water. Avoid touching sticky leaves. Never use fertilizer—plant feeds on insects. Dormancy: reduce watering in winter.
Flowering
4-8 weeksThin, delicate flower stalks (1-4 inches tall) emerge bearing small white, pink, or pale purple flowers in late spring to summer.
Maintain consistent moisture and humidity. Flowers self-pollinate. Remove spent flowers to encourage energy toward leaf growth.
Seed Production & Dormancy
3-4 monthsSeed capsules develop after flowering. In fall/winter, growth slows dramatically and leaves may turn red (cold dormancy).
Allow dormancy period of 2-3 months in cool (40-50°F), moist conditions. Maintain moisture but reduce light slightly. Resume normal care in spring.

Common Pests
-
Ensure excellent air circulation; allow soil surface to dry slightly between waterings; use yellow sticky traps; avoid overwatering.
-
Use sterile, well-draining sphagnum mix; ensure pot has drainage; avoid standing water in base tray; use distilled water only.
-
Increase humidity to 70%+; mist with distilled water; ensure good air circulation; avoid pesticides (toxic to plant).
-
Remove with tweezers or cotton swab dipped in rubbing alcohol; isolate affected plants; maintain high humidity and airflow.
Uses
Natural Insect Control
HouseholdDrosera intermedia actively traps and digests flying insects (gnats, mosquito larvae, small flies), making it an excellent natural pest control plant for indoor spaces and humid terrariums. [source]
Traditional Herbal Remedy
MedicinalHistorically used in traditional European medicine as a remedy for coughs and respiratory conditions. Contains compounds believed to have antispasmodic properties, though scientific evidence remains limited. [source]
Botanical Specimen & Terrarium
CraftPopular among plant collectors and in specialty bog gardens, terrariums, and vivaria. The distinctive dewdrop-covered leaves make it an attractive living display plant. [source]
Pollinator & Insect Support
WildlifeProduces delicate flowers that attract small pollinators in spring/summer while simultaneously being a predatory specialist for nuisance flying insects in the garden ecosystem. [source]
Culinary Garnish & Curiosity
CulinaryWhile not typically eaten, D. intermedia is occasionally used as a garnish in upscale botanical cuisine or molecular gastronomy to create striking visual presentations. [source]

Harvest Tips
Do not harvest leaves. Collect seeds from dried seed capsules in late summer/fall once they turn brown and papery. Seeds are viable immediately but benefit from a cold, moist stratification period of 1-2 months before sowing.
Fun Facts
- 🌱 Drosera intermedia's sticky tentacles (called trichomes) can curl around prey in minutes, and the plant can dissolve insect exoskeletons using digestive enzymes secreted from glandular hairs—essentially digesting insects alive.
- 🌱 The name 'sundew' comes from the morning appearance of dew-like secretions glistening on the leaf tentacles, which Darwin famously studied and noted was actually sticky insect-trapping mucilage.
- 🌱 D. intermedia is one of the few carnivorous plants that can thrive in cool temperate zones and even tolerate brief freezing during winter dormancy in zones 3-4, making it hardier than many exotic carnivorous plants.
