Bucephalandra Red Evil 1 rizome (also known as Red Devil) is a highly sought-after variety of Bucephalandra, an epiphytic plant from the Araceae family native to Nanga Pinoh in West Kalimantan, Borneo (Indonesia). It is one of the true “gems” of aquascaping thanks to its intense, metallic colors that range from vivid red to deep burgundy, purple-black with iridescent highlights. ### Plant Description The Bucephalandra Red Evil features oval-elongated leaves that are slightly wavy with a characteristic “bullate” (bumpy, textured) surface, giving them an almost velvety appearance under light. The leaves typically measure 3cm long and 1–1.5 cm wide. As clearly visible in your photos, the plant displays a beautiful **color variation**: - New leaves emerge in a **bright, intense red**. - Mature leaves shift to **deep purple/black** with striking metallic sheen. - Some transitional leaves remain green. The rhizome is sturdy and creeping, with strong roots perfect for attaching to wood, rocks, or hardscape. It grows slowly (typical of all Bucephalandra) but is extremely hardy and long-lived. Under optimal conditions it can even flower in the aquarium (typical Araceae spadix and spathe). ### Fun Facts & Curiosities - **Endemic to Nanga Pinoh, Borneo**: It naturally grows on riverbanks and streams with strong currents, alternating between submerged (rainy season) and emersed periods. This adaptation makes it ideal for both fully submerged aquariums and emersed setups like paludariums or grow-outs. - **Collector’s favorite**: The “Red Evil / Red Devil” varieties are among the most prized by enthusiasts for their deep red intensity and iridescent sheen. - **Submerged vs. emersed leaves**: Emersed leaves tend to be greener and less dramatic. Once submerged, they develop the signature vivid red-purple coloration seen in your images. ### Cultivation & Maintenance (Collection Care) **Optimal parameters** (for perfect growth and maximum color intensity — works for both submerged and emersed): - Temperature: **25 °C** - pH: **6.5** - Hardness: **5 °dGH** (soft water) - Lighting: **medium intensity** (full-spectrum 6500K LED) - Photoperiod: **8 hours per day** - CO₂: **25 ppm** (highly recommended for vibrant colors and faster growth) - Fertilization: regular dosing of complete liquid fertilizer rich in iron and micronutrients **Submerged aquarium care** (ideal for maximum color): - Attach to wood or rock with fishing line or plant-safe glue (never bury the rhizome!). - Position: foreground or midground to showcase the colors. - Slow but steady growth. Old leaves may melt during the initial transition (completely normal, especially if coming from emersed cultivation). **Emersed growth & maintaining the intense red color**: 1. **Emersed setup**: Use a paludarium, humid terrarium, or covered container with **90–100 % humidity**. Place water at the bottom and use moist substrate (sphagnum moss or expanded clay). 2. **Lighting**: Medium intensity (6500K LED grow lights or full-spectrum with red emphasis to boost reds). 8 hours per day. 3. **Humidity & air**: Mist regularly or use a lid with ventilation holes for air exchange. Keep temperature stable at 25 °C. 4. **Nutrition**: Diluted liquid fertilizer + micronutrients. Good lighting, CO₂, and feeding are key to developing and keeping the deep red coloration. 5. **Transition tips**: If the plant arrives emersed, submerge it gradually. Emersed leaves may melt, but the rhizome will quickly produce new submerged leaves in brilliant red-purple tones. **Propagation**: Extremely easy — simply divide the rhizome (cut a section with at least 3–4 leaves and some roots, then re-attach). ### Pro tips for keeping the red intense - Use full-spectrum or red-enhanced lighting to maximize pigment development. - Regular iron supplementation prevents yellowing and keeps colors vibrant. - Stable water parameters and frequent partial water changes. - Avoid sudden changes in temperature or hardness (these can cause leaf melt). Bucephalandra Red Evil is a premium, collector-grade plant that is surprisingly easy once acclimated. It grows slowly but rewards you with spectacular colors and an elegant presence in any aquascape or paludarium. Perfect for hobbyists who love rare and collectible plants!
