Lindernia rotundifolia (Lindernia rotundifolia variegated)
The aquatic plant Lindernia rotundifolia is found in fresh waters of India, Sri Lanka, Vietnam, Peru and Madagascar. Belongs to the Norichen family. It grows mainly in swamps and can also be found in the drying riverbeds. It has great similarity with Bacopa of Madagascar. Lindernia owes its name to the Strasbourg botanist Franz Baltazar von Lindern, who discovered and described this plant in 1728.
The stem of this bog plant is creeping, can be raised and branching. Under water, the shoots reach a height of 30 cm. The leaves on the plant are located crosswise. The leaves are about 1 cm long and 0.7 cm wide. Oval shape resembling coins. Coloring light green with delicate yellowish stripes. When flowering in Lindernia, single white flowers with violet impregnations are formed. The fruit is a small box 3 mm in size. The plant blooms at the end of summer, flowers appear on shoots overlooking the surface of the aquarium water.
The plant has a very weak fibrous root system, so if there is a moderate movement of water in the aquarium, it will be very difficult to grow Lindernia. For small aquariums, the plant is perfect and even a novice aquarist can be recommended to grow Lindernia rotundifolia one of the first. The volume of the aquarium should be at least 20 liters.
Soil and plant care
It is good to use clean sand as soil and clay can also be added. A plant likes both. Very responsive to mineral fertilizers. Loves good lighting. In low light conditions, the leaves become very small and pale, and the lower leaves can completely crumble. Can be fed with carbon dioxide.
With the right fit and caring care, Lindernia will grow very quickly. After planting a small twig in the nutrient soil in the aquarium after a couple of months, you can get a real forest from Lindernii.
Location in the aquarium
The plant builds a bizarre hedge and perfectly decorates the back wall of the aquarium. At the surface of the water forms an unusual green carpet, where it is good to swim fish and fry. In the foreground, it is better to alternate long stems with short ones to get a favorable contrast with larger underwater plants.
In order for a plant to be beautifully located in the aquarium, it is necessary to plant several stems at once.
Conditions of detention
The temperature of the water for maintenance should be from 20 to 28 degrees. The acidity of water (pH) is from 6.5 to 7.5. Change the water once every two weeks.
Lindernii need continuous lighting with fluorescent lamps for at least 10 hours. Light intensity from 0.5 to 0.7 W / l.
Lindernia propagates by dividing the stems. You can cut off the tops of plants and immediately plant in nutrient soil in a new place. Young plants take root well with sufficient lighting and grow quickly. Lindernii has no rotundifolia.
It is necessary to rejuvenate the plant more often by trimming the tops and thinning out the thickened planting, since if Lindernia grows more than 20 cm tall, weak roots may not hold it and the plant is easily pulled out of the ground.
You can contain this plant and in surface form. To do this, it is placed in a glass vessel with a lid and placed on a well-lit window sill.
