Sundew 4 Pack- Drosera Intermedia

Introduce a dynamic, highly architectural layer of living pest defense to your collection! This curated Sundew 4-Pack features four healthy, established specimens of Drosera intermedia, an exceptionally resilient and adaptable carnivore celebrated for its distinct, spoon-to-oblong-shaped leaves and decumbent growth habit. Unlike completely ground-hugging rosettes, Drosera intermedia sends up semi-erect, gracefully curving leaf petioles that glisten with hundreds of dew-tipped tentacles. With four individual plants, you can establish an intensive, multi-angled flypaper grid across a community bog pot, terrarium, or greenhouse shelf to effortlessly eliminate flying pests.

Why You’ll Love It:

• Distinct Semi-Erect Architecture: Drosera intermedia features beautifully elongated, oblong leaf blades that curve outward and upward, creating a distinct texturized look that beautifully fills out empty spaces in bog displays.

• Aggressive Aerial Trap Grid: Every leaf is densely coated with ruby-red, gland-tipped tentacles that secrete an incredibly sticky, viscous mucilage. It acts as an elite biological trap for annoying flying invaders like fungus gnats, shore flies, fruit flies, and small mosquitoes.

• Stunning Crimson Coloration: Under optimal high-intensity lighting conditions, this highly photogenic variety sheds its baseline lime-green color and flushes into a brilliant, deep scarlet and maroon hue.

The Science of the Trap: Active Tentacle Incurvation & Digestion

Drosera intermedia is a marvel of evolutionary plant biology, executing precise mechanical captures powered by intricate internal communication systems:

1. The Anthocyanin Lure: Driven by strong, high-intensity light, the plant actively synthesizes anthocyanins—vibrant red pigments that saturate the tentacle stalks. Foraging insects are naturally drawn to this rich color contrast and the shimmering, light-refracting dew droplets, mistaking them for an abundance of fresh nectar.

2. The Action Potential Reflex: The moment a flying pest makes contact with a dew droplet and struggles, mechanosensitive ion channels instantly fire. A massive electrical impulse called an Action Potential surges through the leaf tissue at speeds up to 9 mm/s, signaling the surrounding tentacles to bend dynamically inward to pin the insect flat against the leaf surface.

3. The Metabolic Digest: Once the prey is securely locked down, the leaf surface triggers its internal Jasmonate (JA) signaling pathway. Instead of using this hormone for standard tissue healing, the sundew commands its glands to secrete a powerful cocktail of digestive enzymes that dissolve the insect's soft tissues over several days, absorbing critical nitrogen and phosphorus to fuel heavy seed production.

Cultivation & Care Guide

Because Drosera intermedia is a remarkably tough and highly adaptable species, managing a group of them together is completely straightforward:

• Light (The Dew Booster): High-light intensity is absolute critical. To maintain functional traps and trigger deep ruby-red coloration, provide full sun or place them 6–10 inches beneath a high-output LED grow light (5000K–6500K) for 12–16 hours daily. Low light will cause them to turn solid green and drop their dew.

• Water: Keep the substrate continuously waterlogged utilizing the tray method. Always sit the pots in a shallow saucer or tray kept filled with 1–2 inches of pure water (distilled, reverse osmosis, or rainwater only). Tap water minerals will instantly burn their sensitive roots.

• Substrate: Plant strictly in an unfertilized, nutrient-deficient mix of 1:1 pure peat moss and perlite or coarse silica sand. Regular potting soils or standard commercial fertilizers will instantly destroy their specialized root networks.

• Winter Care Dynamics: Depending on the specific geographical locale of your stock, Drosera intermedia is highly adaptable. Temperate strains will form a tight, protective winter resting bud (hibernaculum) and naturally undergo a cold winter dormancy to recover for spring, while tropical variants can happily grow year-round indoors under warm, ambient conditions.
