Drosera binata var. multifida

flower

Forked Sundew is a carnivorous plant native to Australia featuring distinctive narrow, forked leaves covered in sticky tentacle-like glandular hairs that trap small insects. It produces delicate pink or white flowers on tall stems and is prized by enthusiasts for its exotic appearance and fascinating predatory mechanism. This is a slow-growing, long-lived plant that requires specialized care to thrive in cultivation.

Growing Conditions

☀️
Sun: Bright indirect light, 4-6 hours of filtered sunlight daily; can tolerate partial shade but prefers bright conditions
💧
Water: Keep constantly moist but not waterlogged; use distilled water or rainwater only, never tap water due to mineral sensitivity; maintain high humidity (60-80%)
📏
Spacing: 6 inches
📅
Days to maturity: 180-365+ (slow-growing; can take 1-2+ years to reach mature size)
🌱
Planting depth: Surface sowing; seeds require light to germinate, press lightly into moist substrate without burying

Soil

Type: Nutrient-poor, acidic, free-draining mix (peat moss or sphagnum moss with perlite or sand)
pH: 4.5-5.5
Amendments:
Long-fiber sphagnum moss Perlite Coarse sand Avoid standard potting soil and fertilizers

Growth Stages

1

Germination

2-4 weeks

Tiny rosettes of thread-like leaves appear with minimal visible traps

Maintain consistent moisture and bright light; provide high humidity under clear plastic or glass cover; germination takes 2-4 weeks

2

Seedling Development

2-4 months

Leaves gradually lengthen and develop forked tips; initial trap tentacles become visible as sticky red or orange structures

Keep in humid environment; ensure bright light; use distilled water only; avoid disturbance; trap production accelerates with good light

3

Vegetative Growth

6-18 months

Plant develops characteristic deeply forked leaves arranged in rosette formation; leaves grow 4-8 inches long with numerous sticky glandular tentacles

Maintain bright conditions and high humidity; use only distilled/rainwater; ensure excellent drainage; no fertilizer needed; can be grown under grow lights indoors

4

Flowering

4-8 weeks

Thin flower stems (inflorescences) emerge from center or sides of rosette bearing delicate pale pink, white, or occasionally darker pink flowers arranged in clusters

Support flower stems as they can be fragile; pollinate flowers manually with small brush if insects unavailable; provide consistent care during blooming

5

Seed Production & Dormancy

6-12 weeks (seed development); dormancy varies by conditions

After pollination, seed capsules develop containing hundreds of tiny seeds; plant may enter dormancy period or continue growing depending on conditions

Allow seeds to mature and dry on plant; collect when capsules dry and open; may require cold period or dry dormancy for next growing cycle

Companion Planting

Plan your garden →

Plant with:

Other Drosera species Pitcher plants (Nepenthes, Sarracenia) Venus flytrap (Dionaea muscipula) Butterworts (Pinguicula species) Sundews of different varieties

Avoid planting near:

Standard potted houseplants Plants requiring regular fertilization Plants preferring dry conditions Non-carnivorous plants competing for moisture and nutrients

Common Pests

  • Improve air circulation; allow soil surface to dry slightly between watering cycles; use sticky traps; maintain high humidity to discourage some species; carnivorous plant already helps control small flying insects

  • and

    Ensure adequate air circulation with small fan; avoid crowding plants; use sterile tools; remove affected leaves promptly; provide bright light; reduce humidity slightly if persistent

  • Use distilled water only; ensure perlite/sand layer for drainage; repot if necessary into fresh media; allow slightly more air circulation

  • Increase humidity; improve air circulation; inspect regularly; remove severely affected leaves; can mist with water as carnivorous plants tolerate moisture well

Uses

🦋

Natural Insect Control

Wildlife

The sticky trap tentacles passively capture small flying insects like gnats, fruit flies, and mosquitoes, helping control household pest populations. This makes it useful as a biological pest control agent indoors or in enclosed garden spaces. [source]

🏠

Indoor Houseplant & Conversation Piece

Household

Its exotic appearance and fascinating predatory mechanism make it a striking decorative plant for windowsills, plant collections, and terrariums. It appeals to plant enthusiasts and serves as an educational example of carnivorous plant adaptations. [source]

💊

Traditional Medicine Interest

Medicinal

Sundews have been used in traditional herbal medicine in various cultures, particularly in preparations for respiratory conditions and cough remedies. Modern research has identified compounds with potential antimicrobial and antispasmodic properties. [source]

🎨

Botanical Collection & Seed Propagation

Craft

Enthusiasts collect rare Drosera varieties and propagate them from seeds, sharing specimens through specialized plant networks. Growing from seed offers a rewarding long-term horticultural project. [source]

🦋

Botanical Study & Carnivorous Plant Research

Wildlife

Scientists and educators use sundews as model organisms to study plant-insect interactions, carnivory evolution, and adaptive mechanisms. Its accessibility in cultivation makes it valuable for educational demonstrations. [source]

Harvest Tips

Do not harvest leaves or flowers for use; instead, allow the plant to naturally trap and digest small insects for nutrition. Collect seed capsules only after they have completely dried and split open naturally; seeds can be harvested dry. Avoid touching traps as this damages the sensitive glandular hairs. Allow flowering to proceed naturally for seed production, but remove spent flowers to redirect energy if desired.

Fun Facts

  • 🌱 The 'sundew' name comes from the sparkling appearance of the sticky droplets on the tentacle-like glands, which resemble dewdrops glistening in sunlight and attract insects to their doom.
  • 🌱 Drosera binata var. multifida is native to subtropical and tropical regions of eastern Australia and produces one of the most complexly forked leaf structures among Drosera species, with some leaves dividing into 20+ finger-like segments.
  • 🌱 Unlike passive traps, sundew tentacles actively bend toward trapped prey after capture, slowly moving the insect toward the center of the rosette where digestive enzymes are secreted over several days to weeks.
