Pink Sundew is a small carnivorous plant native to the southeastern United States, characterized by reddish-pink glandular tentacles that trap and digest insects.

These delicate plants thrive in boggy, nutrient-poor environments where they supplement their diet with prey.

Growth Stages

1

Seed germination

2-4 weeks

Tiny seeds on soil surface; no covering required; seeds are dust-like and difficult to see

Maintain high humidity and consistent moisture; provide bright light; germination takes 2-4 weeks

2

Rosette establishment

6-8 weeks

Small rosette of 4-8 leaves forms; glandular tentacles become visible and sticky

Maintain boggy conditions; never allow soil to dry out; provide bright light

3

Vegetative growth

8-12 weeks

Rosette expands with 15-25 leaves; plant remains compact and low-growing

Continue wet, acidic conditions; ensure good air circulation to prevent fungal issues

4

Flowering

4-8 weeks

Delicate pink to white flowers emerge on thin stalks above the rosette in summer

Maintain moisture; do not disturb flowering stalks; flowers may produce seeds

5

Dormancy (seasonal)

varies

Plant may slow growth or enter dormancy in winter depending on climate

Reduce watering slightly but keep soil moist; maintain cooler temperatures if possible

Harvest Tips

Do not harvest the plant itself as it is ornamental and carnivorous. Collect seeds from dried flower stalks after blooming; allow seed pods to fully mature and dry on the plant before harvesting; store seeds in cool, dry conditions

Fun Facts

  • 🌱 The sticky 'dew' droplets on Pink Sundew's leaves are actually adhesive digestive secretions that trap insects; once stuck, the plant's tentacles slowly curl inward to bring prey to the center where it is digested over several days
  • 🌱 Pink Sundew can thrive in soils so nutrient-poor that most plants would starve, because it supplements its diet by dissolving and absorbing nutrients from trapped insects—an adaptation to boggy environments
  • 🌱 The plant's common name 'sundew' refers to the way morning dew catches on the sticky tentacles, making them glisten like jewels in the sunlight, though the 'dew' is not water but the plant's own sticky secretions
