Where Lysimachia Nummularia Aquarium plant grow?

The Lysimachia Nummularia Aquarium in meadows, pastures, along the banks of rivers, swamps, and lakes in Europe, North America, China, Japan, preferring low-lying damp areas, including those that are flooded for short or long periods of time. The plant easily adapts both to life in relatively dry conditions and to life underwater. The loosestrife feels best in places that are brightly lit by the sun’s rays. In the design of gardens, it is used as ground cover and ampel components.

what does Lysimachia Nummularia Aquarium plant look like?

When developing on land, the Lysimachia Nummularia forms creeping shoots up to 60 cm long. Roots and leaves are formed at the nodes of the above-water shoots. Upon contact with the ground, rooting occurs and new shoots begin to grow.

A thick carpet of stems creeping on the ground, covered with small rounded leaves of bright green color and yellow sparkles-flowers, involuntarily evoke an association with placers of coins. Therefore, the plant has received so many synonymous names associated with this image.

The leaves of the Lysimachia Nummularia are round, 3 cm in size, on short stalks, arranged in pairs opposite each other. In terrestrial forms, they are colored green or yellow-green. From May to July, the plant blooms with single yellow flowers.

Under water, the plant has the ability to keep its stems upright. The stems of the Lysimachia Nummularia branch a little, so it looks decorative in a group planting. In the aquarium, a group of Creeping Jenny aquarium looks like a small graceful bush up to 25 cm high with small rounded leaves of a bright light green color, reminiscent of a pile of coins.

Does not bloom when submerged.

Lysimachia Nummularia Aquarium care

The Lysimachia Nummularia is not suitable for keeping in warm tropical aquariums. For her to feel good, look smart and be an adornment of the underwater landscape, it is necessary to place her in favorable conditions of existence.

Primary requirements:

  • an aquarium with a volume of 20 liters or more, if there is a chance that the specimen will grow beyond its limits, you can use a lid;
  • clean, constantly filtered water with a weekly change of at least 30% of the total volume;
  • pH value from 6 to 8;
  • temperature + 16 … + 22 ° C, exceeding these values ​​stimulates accelerated growth and elongation of shoots, shrinking leaves, which can lead to the loss of decorative qualities;
  • the degree of mineralization (hardness) 6-15 ° F;
  • bright fluorescent lighting for 12 hours, with insufficient lighting, the lower leaves degenerate, exposing the stem;
  • slightly silted soil, with a lack of nutrients, additional lateral roots grow from the nodes under the leaves (the plant is trying to get food from the water);
  • coarse sand, small pebbles are suitable as a substrate.

These conditions are conducive to gradual growth up to 5 cm per week.

The preferred location in the aquarium is in the middle ground, closer to the side glass, where there is more natural light.

As a care, it is recommended to periodically feed under the root and to trim to maintain the desired height and shape of the fast-growing plant. Cut tops, when planted side by side, will quickly take root and begin to grow. The thickets of lysimachia created in this way will serve as a favorite recreation area, where flocks of small fish will play and hide in the leaves of the plant.

Lysimachia Nummularia Aquarium propagation

When breeding aquarium plants, vegetative propagation methods are used. In the case of the Lysimachia Nummularia, the simplest and most commonly used method is side branch breeding.

The best time to root a Lysimachia Nummularia is late spring and summer.

Reproduction should be done as follows:

  1. Add top dressing to the soil at the planting site of the new specimen and add a lump of clay.
  2. Separate a lateral shoot or cut off the top from an overgrown mother plant.
  3. Immediately root the child shoot in a new location.

The second method is dividing the rhizome of an adult underwater plant.

Among amateurs, there is the experience of placing plants taken from the above-water environment into the aquarium: from the garden, from the shore of a reservoir, from swampy ponds. Experiments in most cases are successful: plants quickly take root and exist in new conditions. Following this example, it is recommended to take preventive measures against the possible introduction of infection into the underwater microcosm: thoroughly rinse the seedling, keep it in quarantine, and, if necessary, treat it with a fungicide.

Seed propagation is also possible:

  1. In August-September, collect seeds that have ripened on loosestrife growing in their natural environment, on land.
  2. Sow seeds in a container with a substrate containing silt and sand.
  3. Transfer the seedlings in the form of several leaves to the aquarium.

The presence of a Lysimachia Nummularia in the aquarium adds originality to the picture of the underwater world, which is created by its owner.
