The homeland of Echinodus large-leaved are the swampy waters of Nicaragua, Venezuela and Argentina. It is worth noting that the plant in natural conditions is quite rare.
This explains the fact that this plant is not widespread among aquarists.
Description: powerful marsh plant. Petiole up to 1 m long, rounded in diameter, bare (ssp. Macrophyllus) or bumpy with stellate hairs (ssp. Scaber).
The lateral leaf blade is 15–40 cm long, 3–25 cm wide, from ovate to broadly ovate, with a blunt, rounded or broken tip, and also with a heart-shaped base. It has (7–9) 11–13 veins.
The underside of the leaf is covered with shaggy pimples. Underwater lamina is smaller, with brownish spots, in most cases with 7-9 veins.
Transparent patterns are missing.
In aquariums, it is usually used as a single background plant. Caring for them is reduced to the periodic introduction of soil fertilizing and timely pruning of air leaves.
Reacts positively echinodus large for a gentle flow and regular water changes.
Vegetative reproduction – the separation of daughter plants, in a large number of flower arrows, which develop on a regularly emitted shrub.
The Latin name is echinodorus macrophyllus.
Large-leaved echinodorus propagates by dividing the rhizome, or with the help of seeds. Under acceptable conditions, the plant often blooms and bears fruit.
After the seeds are collected from the plant, they are stored in a warm, dry place for 1-2 months. After the seeds are planted in the ground and while maintaining the water temperature at around 28 ° C, the first sprouts appear in about a week.
It should be noted that to achieve good germination can be, if you put the seeds in a gauze flap and hang it over water and in this form to withstand within 48 hours.
