White-headed Hydrocotyl or Hawthorn (Hydrocotyle leucocephala)
Hydrocotyl white-headed or thyroid (Hydrocotyle leucocephala) - comes from the umbelliferous family, a native of the hot part of South America (grows in both flowing waters and standing).
An aquarium resident who is not at all capricious, which ensured its widespread distribution and accessibility not only in America, but also on the European mainland.
In appearance, the thyristol is very unobtrusive, slightly greenish round leaves, with a diameter mostly not exceeding 4 cm, branch off from the main stem and alternately grow, resembling grape leaves. The height can reach 50 cm. Each leaf at its base is adjacent to the white shoots, which are the roots of the plant.
Thus, the space in the water is filled. When the hydrocotyl grows to the surface and above, small white flowers begin to appear, subsequently adorning the entire body of water with flowering, creeping along its surface. When planting a plant, the background of the aquarium will be the best place for it. In some cases, the leaves can create a shadow for other plants, preventing them from getting the right amount of light, then we need to deal with thinning of the thyfoil. Also, its presence in the aquarium will serve as a good shelter for fry, saving them from possible dangers.
Conditions of detention
There are no special requirements for the growth of a bald-headed hydrocotyl. The plant growth rate under favorable conditions is surprising; in a week, a height of up to 10 cm is achieved. With sufficient lighting and CO2 saturation, it can even exceed this indicator. The lack of lighting and power will affect growth not for the better. The iron richness in the aquarium is important, the yellowing edges of the leaves, as well as the much reduced size of new sprouts, will be an indicator of its lack. The plant can be planted both in the ground and simply in the water, and one and the other location will not affect its future life. When planting in the ground, no requirements are imposed on the soil. The optimum temperature for good growth is 22-28 ° C. The closest attention should be paid to lighting. Fluorescent and incandescent lamps have different powers, as a result, the former will not cause any harm, and the latter can burn leaves that are on the surface. 12 hours is the minimum of daylight hours for the shistolistnik, if you ignore this moment, it can begin to hurt and eventually die. In its undemanding nature, the wormwood is suitable even for beginners. The inconvenience of growing in a very small aquarium, because of the speed of growth, it will often be required to cut leaves that rise above the water.
The method of propagation of a white-headed hydrocotyl, as well as other long-stemmed plants, is cuttings. With just one cut, and with minimal effort, you can get a full new plant. The upper stalk is nipped off, possibly even with several leaves, and sits in the ground. One week is enough for the cuttings to take root and begin to grow. Thus, this plant can be bred even in large quantities. If there is no soil in the aquarium, the stalk simply remains on the surface of the water. And when the first leaves appear, you can already immerse in water.
The interesting shape and rapid growth of the leaves of the white-headed thyfoil cannot be used to create a full-fledged design in the aquarium. Thistle tree can be both a background plant, and the main one, it will be combined with almost all other inhabitants of the aquarium. The original look will refresh the big picture.
