Echinodorus 'Dschungelstar' Nr. 16

Geographical Origin & Habitat:

This intricately patterned, elite botanical cultivar does not exist in nature. Echinodorus "Dschungelstar No. 16" (Red Flame) is a breathtakingly specialized commercial hybrid created by the world-famous Dennerle nurseries in Germany. It was meticulously crossbred from wild South American Amazon Sword stock, specifically E. ozelot, to create a smaller, intensely red-patterned centerpiece. In the aquarium, it behaves perfectly like its wild ancestors, acting as a highly resilient, deeply rooted amphibious rosette plant.

Taxonomy & Genetics:

Scientifically classified within the Alismataceae family, it is a highly prized, modern "Dschungelstar" (Jungle Star) hybrid. Taxonomically, it is globally famed under the trade name "Red Flame." Genetically, it inherited the incredibly robust health of the E. ozelot lineage. However, its true defining feature is a spectacular genetic mutation that forces the intense, continuous production of hyper-concentrated dark-red to brown anthocyanin pigments in a massive, densely splattered pattern across a bright green or bronze background.

Physical Structure:

The architectural structure of the "Red Flame" sword is deeply compact, highly structural, and fiercely disciplined. It is a rosette plant completely lacking vertical stems. The foundation is a massive, incredibly thick, tuberous subterranean rhizome that deploys an aggressive, deep-reaching root system. The leaves erupt tightly from the crown on distinct, extremely stiff petioles. The foliage is strictly broadly ovate to slightly elliptical, perfectly medium-sized (20-30 cm), and incredibly rigid with softly ruffled edges.

Color & Texture:

The coloration is absolutely explosive, sharply contrasted, and visually mesmerizing. Grown submerged under intense lighting, the rigid leaves possess a bright apple-green to soft-bronze base canvas. This canvas is aggressively and heavily splattered with massive, intensely dark-red to muddy burgundy spots (flames), creating a striking patterned effect. Unlike the tiny speckles of the Python sword, the Red Flame has large, dramatic blotches. The texture is intensely rigid, heavily leathery, and smooth, feeling exactly like hard plastic.

Lighting & CO2:

It is an incredibly resilient, heavily patterned hybrid that demands energy to maintain its aesthetic. While it will technically survive in shaded environments, its spectacular genetics will completely fail; the massive red "flame" blotches will vanish entirely, and the leaves will fade to a dull muddy green. To unlock its compact rosette shape and force the extreme contrast of the red splatters, blasting, high-intensity LED lighting is absolutely mandatory. Pressurized CO2 drastically speeds up its growth.

Nutrition & Substrate:

As a highly specialized, intensely pigmented Amazon Sword hybrid, the "Red Flame" is an absolute, obligate root feeder. Its massive root system strictly demands a very deep (minimum 5 cm / 2 inches), heavily nutrient-dense substrate. It absolutely demands premium aquasoil heavily enriched with iron and macro-nutrient root tabs directly beneath the massive tuber to fuel its intense red speckled pigmentation. If starved of root nutrients, the dense patterned leaves will quickly turn pale yellow, rot, and dissolve.

Water Chemistry:

Originating from highly stabilized nursery conditions, it is practically invincible regarding standard water parameters. It thrives effortlessly in heated tropical aquariums (22-28°C) and is exceptionally adaptable, comfortably tolerating both soft, acidic blackwater and rock-hard, highly alkaline tap water (pH 6.0 - 8.0). The single most critical environmental requirement is absolute chemical stability. It drastically prefers stable, unchanging parameters over perfectly optimized ones. It demands moderate water flow to keep its rigid leaves clean.

Space Management & Placement:

Due to its deliberately compact size (rarely exceeding 20-30 cm height), intensely rigid ovate leaves, and commanding, red-splattered contrasting color, "Red Flame" is an elite, indestructible midground centerpiece for medium to large aquariums. It MUST be planted as a singular focal point directly in the midground, entirely isolated from other patterned plants. Because it grows as a dense, disciplined rosette, it provides a perfectly organized visual anchor that violently draws the eye to its center without overgrowing the tank.

Pruning:

Pruning is a simple, highly necessary procedure to maintain its dense aesthetic. Never attempt to trim a rigid leaf in half; the cut edge will instantly turn black, rot, and destroy the aesthetic. To prune dead, yellowing, or algae-covered older leaves, you must reach deep down into the absolute base of the dense rosette and cleanly snap or slice the stiff petiole directly at the crown. It rarely spreads via runners; instead, it slowly forms a massive, impenetrable, single-crowned anchor.

Risks & Diseases:

The absolute greatest threat to the "Red Flame" sword is Green Spot Algae (GSA) and nutrient starvation. Because the highly rigid, smooth leaves live for years and grow relatively slowly, they act as massive landing pads for devastating Green Spot Algae if phosphate levels drop or light is too intense without adequate CO2. Once GSA aggressively spots the tough leaves, it is physically impossible to clean off and ruins the contrasting patterned aesthetic. The second risk is nutrient starvation; if root tabs run out, it will melt.
