Species description

This exceptional horticultural variety, named 'Roter Oktober' (Red October), is a cultivated hybrid developed in Europe, particularly in Germany. It does not exist in the wild. The genus Echinodorus has its evolutionary roots in the wetlands, marshes, and riverine areas of Central and South America. This selection was created to stabilize a compact growth habit combined with an intense and long-lasting red The name of the cultivar reflects its main visual feature: new leaves emerge from the center of the rosette with an extremely intense and deep ruby-red or blood-red color. Unlike other red hybrids, mature leaves maintain a reddish-brown or dark olive-green hue for a long time before turning completely green.

Care, breeding and tankmates

Tolerates a wide spectrum of values, with ideal temperatures ranging between 15°C and 30°C. Adapts to acidic or neutral pH (5.0 - 7.0) and water hardness (KH) from very low to medium. It is a robust plant that responds positively to regular partial water changes that keep the water clear and free of organic excesses. It is subject to iron chlorosis in case of iron deficiency, which manifests as faded or transparent new leaves. The thick, moderately growing leaves can be colonized by brush algae or green spot algae if there are nutrient imbalances or fluctuations in CO2 levels in the aquarium.

Plant profile

Placement
Midground

Due to its size and growth pattern, Echinodorus 'Roter Oktober' is best suited for the midground or background of the aquarium. It creates a striking focal point with its dark red leaves when placed centrally. Ensure it has enough space around it as it can grow quite broad and cast shade on smaller plants.

Botanical form
Rosette

This plant grows in a classic rosette form, with leaves emerging from a central crown. The leaves of Echinodorus 'Roter Oktober' can become quite large and display a beautiful dark red hue. Its strong, established root system anchors the plant firmly in the substrate.

Growth
Medium

The growth rate of Echinodorus 'Roter Oktober' is moderate to fast, depending on the availability of nutrients and light. Under high light and CO2 injection, it will produce new leaves rapidly. In low-tech setups, it will grow more slowly but remain healthy.

Substrate
High
Column fertilization
Recommended

While primarily a root feeder, Echinodorus 'Roter Oktober' still benefits from comprehensive liquid fertilizers in the water column. Potassium and iron supplements can enhance the vibrancy of its dark red leaves. Regular dosing prevents deficiencies that might otherwise lead to yellowing or pinholes.

Root fertilization
Recommended

Root fertilization is critical for the success of Echinodorus 'Roter Oktober'. Use high-quality root tabs placed deep in the substrate near the base of the plant. Replenish these root tabs every few months to ensure continuous robust growth and strong coloration.

Trimming
Occasional

Trimming Echinodorus 'Roter Oktober' is straightforward; simply cut older, damaged, or overly large outer leaves as close to the crown as possible. Do not cut the leaves in half, as the remaining stalk will rot. Regular pruning encourages the plant to produce fresh, brightly colored new growth.

Propagation
Division

Propagation of Echinodorus 'Roter Oktober' occurs primarily through adventitious shoots that form on long flower stalks. Once these young plantlets have developed a few leaves and their own root system, they can be carefully detached. Replant these daughter plants directly into the substrate.

Sensitivity
Moderate

Echinodorus 'Roter Oktober' is generally quite hardy and adaptable to a range of water parameters. It is not particularly sensitive to most common aquarium medications or liquid carbon products. However, sudden extreme changes in water chemistry should still be avoided to prevent melting.

Layout role
Midground, accent

In an aquascape, Echinodorus 'Roter Oktober' serves as a magnificent centerpiece or structural background plant. Its dark red foliage provides excellent contrast against green stem plants and hardscape materials. It brings a natural, robust texture that anchors the overall design.
