Echinodor is a rhizomatous aquatic plant native to South America. As the plant develops, it forms dense rosettes of leaves, some of which always remain submerged, of an elliptical shape, with wavy margins; others, on the other hand, grow up to 50-60 cm and then emerge from the water, on long erect petioles, have an elongated, pointed oval shape, bright light green, sometimes dotted with purple or colored on the margin of the lower page.

In summer they produce emerged inflorescences, consisting of large rounded buds that grow at the apex of erect fleshy stems, from them flowers with a yellow center and candid white petals, with three petals, that resemble poppies bloom. These plants are often used as flora for aquariums and this use is the main one for this plant.


The plants of echinodorus they need abundant light throughout the year; moreover they are species that fear the cold, therefore they can be placed outside in spring and summer, but they must be kept in containers in a greenhouse or at home in the cold months of the year; if desired, it can also be grown as an annual plant. The rhizomes are planted in spring, on the bottom of slow water streams or lakes, completely submerged by water. In its natural state, the plant grows under water and then develops stronger leaves once the stem pokes out of the water. A thin wax-like layer forms on them which allows the leaves not to be burned by the intense sun of the summer.


In nature they are species that love soils rich in organic matter, very soft and deep, muddy and sandy, to allow the vigorous roots to spread as desired, they fear too calcareous soils. These plants should be planted in aquariums or on the shores of small lakes, where the water does not exceed 30-40 cm, so that the basal rosette of leaves can always remain submerged, while the outer leaves can emerge. One of the characteristics of the plant is that it produces stolons in an abundant manner, which allows the plant to develop a real green lawn.


In nature the plants of echinodorus they produce fertile flowers, this hardly happens in our latitudes, therefore they propagate by dividing the tufts of leaves; it is advisable to leave a vigorous root for each portion practiced, and to plant directly. As we said previously, the plant continuously produces stolons or lateral branches that sprout from the base of the plant and crawl they make space between the ground, emitting roots and allowing the plant to reproduce. Once it reaches a height of at least 2 cm, it will be possible to separate the new twigs born from the mother stem and grow the new plants in another place. Echinodorus is considered a ground cover plant as its rapid development allows it to cover large surfaces in a short time.

Echinodorus: Parasites and diseases

Beware of aphids; soil or water with too high pH values ​​can cause stunted plant growth. Despite that, being an aquatic species, the echinodorus is not particularly prone to the development of diseases and parasites.
