Echinodoro 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, elliptical in shape, with wavy margins; others instead grow up to 50-60 cm and then emerge from the water, on long erect petioles, have an elongated, pointed oval shape, of a bright light green color, sometimes speckled 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 which flowers with a yellow center and candid white petals, with three petals, reminiscent of 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 need abundant light, all year round; moreover they are species that fear the cold, therefore they can be placed outside in spring and summer, however they must be kept in containers in the 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 waterways or ponds, completely submerged in water. In its natural state, the growth of the plant takes place under water and then develops more resistant leaves once the stem peeps out of the water. A thin, wax-like layer forms on them, which allows the leaves not to be burnt by the intense sunshine of the summer.
