Echinodorus osiris is common in the water bodies of Brazil, found in the province of Parana.
Plant height up to 60 cm, it has a powerful root system with cord-like roots. It produces emergent leaves very rarely, usually when grown in a humid greenhouse. Underwater leaves up to 35-40 cm long and 6-8 cm wide are lanceolate-elliptic, oval at the base, pointed towards the apex, slightly wavy at the edges, with a pronounced central vein. 5 veins are clearly visible. The color of the leaves ranges from dark green in large bushes to carmine red in young plants. The rhizome is large, creeping.

When keeping Echinodorus osiris in an aquarium, the optimum temperature is 22-24 ° C. Raising the temperature to 26 ° C accelerates development, but the plant is depleted and dies quickly. The water should be of medium hardness, 4-16 °, neutral or slightly alkaline (pH 6.8-7.5). The plant does not tolerate soft, slightly acidic water. Periodic replacement of part of the water is desirable. Turbid water is undesirable, as the mud settling on the leaves harms the echinodorus.
The soil should consist of a mixture of peat or leaf earth and sand. During periods of rapid growth, it is necessary to apply mineral fertilizers and microelements, especially ferrous salts. Lighting should be very bright, close to natural in spectral composition. In insufficient light, the plant becomes smaller, sick and dies. Daylight hours should be 10-14 hours. The soil should be nutritious, consist of a mixture of coarse sand with medium to coarse pebbles with an admixture of clay and be moderately silted. With an excess of silt, the plant can rot its roots.

Echinodorus osiris reproduces by seeds, and in the aquarium - vegetatively, forming flower arrows on which daughter plants appear. The arrow, on which the daughter plants have formed, must be pressed against the ground for their rooting. After young plants take root and form 4-5 large leaves, they can be separated from the arrow. The formation of several flower arrows severely depletes the plant and can lead to its death, therefore, extra arrows should be removed. Echinodorus can also form daughter plants on the processes of the rhizome. Young plants can be separated from the rhizome after the formation of 4-5 leaves and 2-3 roots. This method of reproduction does not deplete mother bushes.
