The Pontederian family. Homeland Brazil.
This plant is especially beautiful during flowering, which not everyone can achieve at home. Eichornia's stems are short, and filamentous dark purple pubescent roots. On the stem are rosettes of oval leaves. The leaf petioles are bubble-shaped, filled with air and provide free floating of the plant on the surface of the water (they are often mistaken for bulbs. Flowers appear in summer, on a peduncle coming from the center of the rosette of leaves. The flowers themselves are pink-lilac in color, and one of the petals has a dark spot The flowers last only one day, then the peduncle goes under the water.
How to care for Eichornia
Temperature: Eichornia is thermophilic, it needs about 25-27 ° C, not lower than 22 ° C, and during flowering 28-29 ° C. Eichornia does not tolerate drafts and sudden temperature changes, so the glass covering the aquarium should lie tightly, closing it from drafts if the room is ventilated. But the rest of the time, fresh air is required. For many, this plant dies in aquariums precisely because the lid is on top and the ventilation is too low.
Lighting: the intensity of photosynthesis in eichornia is higher than that of underwater plants, it is photophilous, and shading is not required. In the fall and winter, artificial lighting may be needed, it is best to use fluorescent lamps, as in a regular fish tank. However, a day of light lasting more than 14 hours will lead to rapid growth of plants and it will be necessary to thin out the plantation more often.
Reproduction: vegetatively, developing new plants on lateral shoots. At home, eichornia also reproduces by seeds.
To grow large specimens, fertilizer for common indoor plants or fertilizer for aquarium plants is periodically added to the water for the water hyacinth. If you grow eichornia in a regular aquarium with fish, then it will most likely grind and then simply rot. Eichornia can only be grown in open aquariums or ponds.
When keeping plants in a separate container, you need to pick up a low but spacious aquarium, or a wide vase (in the form of a low basin). Sand with peat additives is used as a substrate; garden soil or pure peat can be used.
The roots are buried in the substrate, the thickening of the petioles raise the leaves to float freely. Those. so much water is poured so that the rising leaves are not covered with water. Under natural conditions, water hyacinth floats freely on the surface of water bodies, but when the water dries, the eichornia takes root in the silt.
