Dewy Pine

Drosophyllum lusitanicum

flower

Drosophyllum lusitanicum is a carnivorous plant native to southwestern Portugal and Morocco, characterized by its long, narrow leaves covered in sticky, glandular tentacles that trap insects. Unlike most carnivorous plants, it thrives in dry conditions and prefers sandy, acidic soils with minimal moisture. This remarkable adaptation makes it one of the most unusual and challenging carnivorous plants to cultivate.

Growth Stages

1

Seed germination

2-4 weeks

Tiny seedlings emerge with fine, hair-like initial leaves; very delicate appearance

Keep sand barely moist but never waterlogged; provide excellent drainage; maintain warm temperatures (70-75°F); use bottom heat if available

2

Seedling establishment

4-8 weeks

Young plants develop characteristic narrow leaves with short tentacles; growth is slow and steady

Gradually reduce moisture; transition to drier conditions; provide full sun; avoid moving or disturbing the plant frequently; maintain warm environment

3

Vegetative growth

8-16 weeks

Plant develops mature rosette form with long, slender leaves densely covered in sticky red tentacles; can reach 6-12 inches tall

Water sparingly; allow long dry periods between waterings; maintain full sun exposure; fertilizing is unnecessary as plant captures insects; ensure excellent air circulation

4

Flowering

3-6 weeks

Small, delicate yellow flowers appear on thin stems emerging from the rosette; flowers are inconspicuous but distinctive

Continue minimal watering; maintain warm, dry conditions; pollination is primarily wind-dependent or may require hand pollination; avoid disturbing flowering stems

5

Seed production and decline

4-8 weeks

After flowering, plant produces small seed pods; energy is devoted to seed production; plant gradually declines

Collect seed pods once they become papery and dry; allow seeds to fully mature before harvest; plant is often short-lived and may die after seed production; collect seeds for propagation

Harvest Tips

Harvest seeds once seed pods turn dry and papery (typically 4-8 weeks after flowering). Allow pods to fully mature on the plant before collection. Store dried seeds in cool, dry conditions. This plant is not harvested for consumption; propagation is primarily through seed collection.

Fun Facts

  • 🌱 Drosophyllum is the only carnivorous plant that thrives in dry conditions rather than wet habitats—it actually rots if kept too moist, making it the opposite of most carnivorous plants.
  • 🌱 The plant produces a sweet-smelling, sticky mucilage on its tentacles that attracts insects; the scent may help lure prey to the plant.
  • 🌱 This species is the sole surviving member of its genus, making it botanically unique and evolutionarily significant among carnivorous plants.
