 Can

be found in wetlands in Mexico and North America.  In USA it occurs in the southeastern states, to Virginia, Illinois and Texas.  Also found in Mexico and the northern states of South America.



Tropica Marble, Marble Queen (variety) are cultivated by Oriental Aquarium in Singapore.

Biology Habitat



Herbs, perennial, stout, to 100 cm; rhizomes present, usually in larger species, whereas smaller species are stoloniferous.



Leaves emersed, submersed leaves mostly absent



It also has a strong tendency to grow above the surface in shallow water (depth 18" and under) and send up leaf blades which are stiffer and have a heart-shape.



Adaptable to basic (alkaline) water, it nonetheless tends to grow better in slightly acidic water. A very extensive root system develops, spreading out for several inches. Inflorescences (floral stocks) will produce adventitious plants when submersed; after a few weeks, these can be carefully removed from the stalk and planted as new plants



Breeding system: Hermaphroditic

Found

in marshes, swamps and ponds. Blooms in the late summer to early fall.

Easily cultivated in neutral to soft water and tropical to sub-tropical temperatures. Rich substrate and good light. Common in the cultivated aquarium trade.  One of the largest of the Echinodorus for aquaria, this species makes a superb specimen in tanks 3-4 feet in length and is excellent as a corner or background plant. In opentop aquaria leaves will often grow emersed (above the surface).  The size is dependent upon the light and nutrient availability; brighter light or a light period of 12+ hours will result in larger leaves above the surface; less light (11 hours duration) will restrain growth, and removing large older leaves and occasionally trimming the roots will keep the plant from growing too large. 

 CO2

infusion helps stronger growth. A heavy feeder and for optimum growth a rich substrate is needed, including clay.  Not fussy as to water conditions, tropical aquarium temperatures. Can be grown outdoors in warmer countries, it does not tolerate frost. Likes a lot of light.  Can be grown in or by the pond in warmer climes. The seeds can be sown in shallow water.  water: pH: 6.5-7.5; 5-15 (19-28°C)

 Echinodorus

cordifolius are efficient for reducing the concentrations of nutrients and organic matter (especially ammonia) in the water ultimately discharged to the environment.
