Echinodorus Reni care guide

Echinodorus Reni (Echinodorus 'Reni') — medium light, 20-28 °C, pH 6-7.5, no CO2.

Overview

Echinodorus Reni (Echinodorus 'Reni') is an aquatic plant of the family Alismataceae, listed in the Aquairi knowledge base as a beginner-level species. It is typically grown under medium light and without obligatory CO2 injection on nutrient-rich aquasoil. A compact red sword plant that maintains its deep wine-red coloration even under moderate light. One of the few truly red rosette plants that stays small enough for midground placement in medium-sized aquariums.

Taxonomy

Family: Alismataceae
Genus: Echinodorus
Scientific name: Echinodorus 'Reni'
Common synonyms: Red Reni Sword

Habitat

Echinodorus is a genus of New-World aquatic and marsh plants (family Alismataceae) widespread from the southern United States through tropical South America; many cultivated forms are nursery hybrids selected for colour and leaf shape. In the Aquairi knowledge base, populations associated with this form are recorded from cultivated.

Growth requirements

Lighting: medium
CO2: not required
Temperature: 20-28 °C (68-82 °F)
pH: 6-7.5
GH: 3-12 °dGH
Substrate: nutrient-rich aquasoil
Maximum height: 20 cm
Growth rate: medium
Recommended placement: midground

Placement

A heavy root feeder for the midground or background. Nutrient-rich substrate, root tabs and stable parameters drive vigorous growth. Larger varieties require generous spacing. In the Aquairi knowledge base this form is recommended for the midground under medium light and without obligatory CO2 injection, using nutrient-rich aquasoil.

Propagation

Reproduces by adventitious plantlets that develop on flower stalks; once a plantlet has formed several leaves and visible roots it can be separated and planted. Documented propagation techniques for this entry include: horizontal runners.

Common issues

Pale or yellowing new leaves usually indicate iron or other micro-nutrient deficiency; root tabs in nutrient-poor substrates correct most cases.
