Sansevieria unites 60-70 species of evergreen stemless plants of the Agave family. The plant owes its Latin name to the Neapolitan prince San Severo, who promoted the development of the natural sciences.
In nature, the plant grows in the tropical regions of Asia and Africa and, thanks to its attractive appearance and unpretentiousness, has deserved the love of gardeners. In Sansevieria, all species can be divided into two types of leaves: with flat and thick leaves.
- Three-lane Sansevieria (Sansevieria trifasciata)
- Big Sansevieria (Sansevieria grandis)
- Hyacinth (Sansevieria hyacinthoides)
- Dunery (Sansevieria dooneri)
- Liberian Sansevieria liberica
- Kirk (Sansevieria kirkii)
- Graceful Sansevieria (Sansevieria gracilis)
- Cilindrika (Sansevieria cylindrica)
Three-lane Sansevieria (Sansevieria trifasciata)
A plant with flat oval leaves, often referred to as "pike tail". Leaves grow from the root zone. They are dark green in color, separated by light transverse stripes. In the outlet they are usually up to 6 pieces.
The size of the sheet in length is 30-120 cm, in width - 2 - 10 cm. The leaf is oval in shape, smooth, at the end it ends with a tip. The intensity of the color of the leaves depends on the illumination of the room.
Three-lane Sansevieria is a common indoor plant and is distinguished by its unpretentiousness.Often it is used as a floor indoor flower. It is well tolerated by any light, but it is better to keep it in bright light.
It is rarely necessary to water the plant, since it stores water in its tissues. Keeping indoors with central heating is comfortable for the plant. The preferred humidity should be low, because the plant is adapted to the dry air of the savannas.
The flower is rather afraid of excess moisture, so the soil between watering should dry out. If the leaves turn yellow, it is necessary to reduce watering. Other reasons simply can not be.
The plant is sensitive to temperatures below 14 ° C, but it tolerates temperature fluctuations and drafts well. The most comfortable is the temperature of 20-32 ° C. The lower the temperature, the less watering should be.
Repot the plant in the spring, if the roots have filled the entire volume of the pot. This usually happens once every 2-3 years. For transplantation, use loose universal substrates, adding 30% of sand. The most suitable substrate for cacti.
Propagated by plant division or leaf cuttings. The most common is division.
To do this, you need to remove the entire plant from the pot along with the earthy clod and with the help of a knife cut the thick roots into pieces, which will contain a sheet rosette of the plant. The separated parts easily take root because they have many small rhizomes.
Reproduction by cuttings more labor intensive. The length of the cutting from a healthy leaf should be no less than 5 cm. Before planting in sandy soil, they are kept a little in the air, and then treated with a root growth stimulator. Roots are formed in about a month.
When feeding the sansverier it is necessary to use fertilizer for cacti. Feeding is necessary to carry out only during the growing season.
Sansevieria is not subject to disease. Improper care can lead to rotting of the roots, resulting in mealybugs, spider mites or scythosis.
This plant is a good indoor air purifier. It absorbs 107 types of toxins from the environment and releases oxygen.
From the original species, many varieties of sansevieri were cultivated, which differ in the size, shape of the leaf and its color. Let's call the main types of pike tail:
