Echinodorus Yellow Sun is an easy, colorful sword for the midground of a medium or large tank.
Did you know
A single healthy rosette of Echinodorus Yellow Sun carries three color stages at once. Pale red new leaves sit in the center, speckled blades sit in between, and yellow-green mature leaves ring the rim.
Caring for Echinodorus Yellow Sun
Plant Echinodorus Yellow Sun in a nutrient-rich substrate or push root tabs in under the crown. Keep the crown itself above the substrate so it does not rot. It also feeds from the water, so a liquid fertilizer helps.
Medium to high light keeps the yellow tone bright and the speckling distinct. CO2 is not required but speeds growth. It is comfortable at 72 to 82°F (22 to 28°C) and a pH of 6 to 7.5.
A mature rosette can reach around 40 cm. Trade stock is usually farm-raised in emersed form and converts to underwater growth after planting. Trim tattered outer leaves at the base. To propagate, take plantlets from the flower stalks or split the crown.
Good to know
Echinodorus Yellow Sun belongs to the family Alismataceae. It is sold only as a hybrid Echinodorus cultivar, and no seller documents the parentage. Its blades carry fine brownish speckling. Like most cultivated swords, it is propagated vegetatively rather than from seed.
In the wild
Echinodorus Yellow Sun is a commercial sword cultivar with no wild range. The species behind it come from the marshes and slow waters of South America. There, swords root in soft mud and spend part of the year emersed and part submersed along the bank.
Common questions
Does Echinodorus Yellow Sun need to be planted in the substrate?
Yes. Bury the roots and leave the crown, where the leaves join, just above the substrate.
Does Echinodorus Yellow Sun need CO2?
No, but it helps. Echinodorus Yellow Sun can grow without injected CO2, and added CO2 makes it grow faster.
How much light does Echinodorus Yellow Sun need?
Echinodorus Yellow Sun wants medium light. A light sold for planted tanks covers it.
Does Echinodorus Yellow Sun need root tabs?
They help. Echinodorus Yellow Sun takes nutrients through both its roots and its leaves. Root tabs near its roots and a liquid fertilizer cover both.
How do you propagate Echinodorus Yellow Sun?
Echinodorus Yellow Sun propagates by rhizome division and plantlets. Cut the rhizome into pieces with several leaves each, then tie or plant each piece. Small plantlets form on the plant and can be detached once they have a few roots.

Echinodorus Yellow Sun grows to about 15.7 in (40 cm) tall. It grows at a moderate pace.
