Overview
Echinodorus 'Marble Queen' (Echinodorus cordifolius 'Marble Queen') 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 stunning variegated sword plant with green and white marbled leaves. A medium-sized hybrid that adds unique color variation to planted aquariums without requiring intense lighting.
Taxonomy
- Family: Alismataceae
- Genus: Echinodorus
- Scientific name: Echinodorus cordifolius 'Marble Queen'
- Common synonyms: Marble Queen 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 Cultivar.
Growth requirements
- Lighting: medium
- CO2: not required
- Temperature: 22-28 °C (72-82 °F)
- pH: 6.5-7.5
- GH: 3-12 °dGH
- Substrate: nutrient-rich aquasoil
- Maximum height: 30 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, adventitious plantlets.
Common issues
Pale or yellowing new leaves usually indicate iron or other micro-nutrient deficiency; root tabs in nutrient-poor substrates correct most cases.
