Echinodorus Dschungelstar Nr. 2 'Kleiner Bär'

Geographical Origin & Habitat:

This specific botanical masterpiece does not exist in the wild. Echinodorus Dschungelstar No. 2 "Kleiner Bär" (Little Bear) is a legendary, world-famous commercial hybrid created by the elite Dennerle nurseries in Germany. It was meticulously crossbred from wild South American Amazon Sword stock to create the ultimate, perfectly proportioned, deeply red centerpiece for smaller aquariums. In the aquarium, it behaves precisely like its wild ancestors, acting as a highly resilient, deeply rooted amphibious rosette plant.

Taxonomy & Genetics:

Scientifically classified within the Alismataceae family, "Kleiner Bär" is arguably the most famous and beloved red Echinodorus cultivar in the global aquascaping hobby. Taxonomically, it is a complex hybrid. Genetically, it inherited the bulletproof survival traits of standard Amazon Swords, but completely suppressed the genetic markers causing giant vertical growth. Crucially, its superior genetics force the extreme, continuous production of highly stable, intensely concentrated deep-red and dark-burgundy anthocyanin pigments across all tissues.

Physical Structure:

The architectural structure of the "Little Bear" sword is exceptionally well-proportioned, intensely compact, and fiercely disciplined. It is a true rosette plant completely lacking vertical stems. The foundation is a massive, thick, tuberous subterranean rhizome that deploys an aggressive, deep-reaching white root system. The leaves erupt tightly from the crown on distinct, extremely stiff petioles. The foliage is strictly broadly elliptic to narrowly ovate, perfectly medium-sized (15-25 cm), and incredibly rigid with very smooth edges.

Color & Texture:

The coloration is absolutely explosive, deeply saturated, and visually commanding. Grown submerged under intense lighting, the rigid leaves erupt in a blindingly bright, glowing rust-red to an intensely dark, moody burgundy or deep brownish-red. Unlike inferior hybrids, the "Little Bear" genetics prevent the mature outer leaves from fading entirely to green; they retain a solid, deeply dark reddish-bronze hue. The texture is intensely rigid, extremely leathery, and deeply "bullate" (hammered/dimpled) across the entire massive leaf surface.

Lighting & CO2:

It is an incredibly resilient, heavily pigmented hybrid perfectly suited for beginner, low-tech aquariums. While it will technically survive in shaded environments, its spectacular genetics will completely fail; the heavily dimpled leaves will lose their blood-red color, fade to a dull muddy green, and stretch upward. To unlock its intensely compact rosette shape and force its blindingly bright, dark-burgundy colors, blasting, high-intensity LED lighting is absolutely mandatory. Pressurized CO2 drastically speeds up its overall growth.

Nutrition & Substrate:

As a highly specialized, intensely pigmented Amazon Sword hybrid, the "Little Bear" 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 dark red pigmentation. If starved of root nutrients, the dense red leaves will quickly turn pale, turn violently yellow, and dissolve.

Water Chemistry:

Originating from highly stabilized German 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 dense core clean.

Space Management & Placement:

Due to its deliberately compact size (rarely exceeding 15-25 cm height), intensely rigid, hammered ovate leaves, and commanding, deep burgundy color, "Kleiner Bär" is the absolute ultimate, indestructible midground centerpiece for medium to large aquariums. It MUST be planted as a singular focal point directly in the exact center midground. Because it grows as a dense, disciplined rosette, it provides a perfectly organized, dark-red 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, dimpled leaf in half; the cut edge will instantly turn black, rot, and destroy the aesthetic. To prune dead, yellowing, or algae-covered older outer 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 dark red core.

Risks & Diseases:

The absolute greatest threat to the "Little Bear" sword is Green Spot Algae (GSA) and nutrient starvation. Because the highly rigid, heavily dimpled 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 deep red aesthetic. The second risk is nutrient starvation; if root tabs run out, it will melt.
