Echinodorus 'Großer Bär'

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Given its impressive stature and broad leaf span, it is best suited as a solitary midground focal point or a dominant background specimen. It needs substantial space around it to properly exhibit its large, slightly undulating foliage. Placing it in an open area prevents it from overshadowing delicate carpeting species.

Botanical form

Rosette

This stunning hybrid forms a large rosette of broad, ovate leaves that transition through a captivating color palette. New leaves emerge in vibrant shades of rust-red or burgundy, gradually maturing into a deep, rich olive-green. The leaves have noticeable longitudinal veins and slightly wavy margins, adding texture to its visual weight.

Growth

Medium

It exhibits a moderate to fast growth rate when provided with intense lighting and abundant nutrients. The plant continually unfurls large, vividly colored new leaves from its center. Supplemental CO2 injection strongly accelerates its growth and maximizes the size and coloration of its foliage.

Substrate

High

Column fertilization

Recommended

Liquid fertilization should complement its primary root feeding to ensure no micronutrient deficiencies occur. Regular dosing of a comprehensive liquid fertilizer, especially one rich in iron and trace elements, prevents chlorosis. However, relying solely on water column dosing will fail to sustain this large sword.

Root fertilization

Required

Consistent, heavy root fertilization is the absolute key to maintaining its robust health and striking colors. Iron-fortified root capsules should be pressed deeply into the substrate near its base every two months. A high-quality aquasoil substrate is highly recommended for long-term vitality.

Trimming

Occasional

Maintenance involves selectively pruning the oldest, outermost leaves as they fade or become covered in algae. Always cut the leaf stems cleanly at the base of the central crown. This not only controls its massive size but redirects the plant's energy into producing highly colored new central leaves.

Propagation

Division

It propagates by developing strong emergent floral stalks that eventually produce several adventitious plantlets. These plantlets can be left on the stalk until they grow a substantial root system and several leaves of their own. They can then be carefully snipped off and replanted.

Sensitivity

Moderate

It is generally hardy but requires high light to maintain its intense red and rusty coloration; in low light, it reverts to plain green. The crown must not be buried in the substrate to prevent rot. It may suffer from iron deficiency, indicated by pale, whitish new growth, if the substrate is depleted.

Layout role

Midground, accent

It acts as a breathtaking centerpiece that draws the eye with its bold mix of red and green hues. Its massive size and texture create a strong contrast against fine-leaved, bright green background stem plants. It is highly effective at breaking up uniform green landscapes.
