Growth Stages

1

Dormancy/Acclimation

1-2 weeks

New plants arrive stressed and may appear wilted or discolored; foliage may be pale or reddish

Provide high humidity (60-80%), warm temperatures (65-75°F), and bright indirect light. Do not repot immediately; allow 1-2 weeks for adjustment before moving to permanent location.

2

Vegetative Growth

6-12 weeks

Rosette expands with new leaves emerging from the center; leaves develop the characteristic lance shape and sticky tentacles

Maintain consistent moisture, warmth, and humidity. Ensure excellent air circulation to prevent fungal issues. Resist the urge to touch sticky leaves or 'feed' the plant; it will catch insects naturally.

3

Flowering

4-8 weeks

Thin flower stalks emerge from the center or sides of the rosette, producing small pink or white flowers arranged in a simple raceme

Continue normal watering and humidity. Flowers are delicate and self-pollinate; do not disturb blooms. Provide pollinating insects or manually pollinate with a small brush if seeds are desired.

4

Seed Production

6-10 weeks

After pollination, small seed pods develop that gradually dry and split open to release dust-like seeds

Allow seeds to mature and dry on the plant. Collect seeds before they scatter. Seeds require stratification (moist, cool period) before germination.

5

Mature Plant

Indefinite; can live 10+ years with proper care

Established rosette reaches full size (typically 2-4 inches across) with multiple leaf clusters and active insect-trapping activity

Maintain all previous conditions indefinitely. Monitor for pests, rot, or nutrient deficiencies. No fertilization needed; the plant obtains nutrients from trapped insects.

Companion Planting

Plan your garden →

Plant with:

other Drosera species Nepenthes (tropical pitcher plants) Sarracenia (in cooler conditions) sphagnum moss low-growing bog plants

Avoid planting near:

fertilized plants tap water sources air pollution sources pesticide-treated areas high-traffic areas with vibrations

Common Pests

  • Improve air circulation, allow soil surface to dry slightly between waterings, use yellow sticky traps, maintain high humidity to discourage breeding

  • and

    Ensure excellent air circulation with a small fan, avoid water on foliage, remove affected leaves immediately, use distilled water only

  • Remove by hand or with a soft brush; quarantine affected plant; spray with water only (no pesticides, as they harm the plant)

  • Use sterile, well-draining medium; ensure pot has drainage holes; water from below; remove and discard rotted portions; repot in fresh medium if necessary

Harvest Tips

This plant is not harvested for food or material. Seeds can be collected by allowing flowers to mature and dry; harvest seed pods when they turn brown and begin to split. Seeds should be stored dry in a cool location or stratified immediately for propagation.

Fun Facts

  • 🌱 Drosera adelae's sticky tentacles (called 'tentacle glands') are covered with mucilaginous secretions that not only trap insects but also contain digestive enzymes that break down prey into nutrients the plant can absorb—a fascinating adaptation to nutrient-poor soils.
  • 🌱 The plant's common name 'sundew' comes from the way morning dew or water droplets cling to the sticky tentacles, making them sparkle in sunlight like tiny jewels, though the 'dew' is actually the plant's own sticky secretion.
  • 🌱 Drosera adelae is native to the tropical rainforests of Australia and grows as an epiphyte or in wet, shaded boggy areas; its preference for high humidity and warm temperatures reflects these humid rainforest origins.
