Astrophytum


Astrophytum (Astrophytum) is attributed by scientists to the cactus family. Its homeland is considered to be the hot and arid regions of the southern United States, as well as Mexico. Astrophytum grows exclusively on stony or sandy soils. The flower got its name from a combination of two Greek words, literally translated as "aster" and "plant". Indeed, if you look at the plant from above, it is easy to see how it and its flower resemble a star with rays-ribs (from 3 to 10 faces) in shape.

Astrophytum, among other types of cacti, is distinguished by a special peculiar beauty. Its stem is spherical and slightly elongated. There are numerous speckled dots on the surface of the stem. Some varieties of astrophytum grow without thorns, while others have thorns, sometimes curved in shape.

Young plants bloom in large yellow flowers with a red center. The flower appears at the very top of the stem. Astrophytum bloom is short - only 2-3 days. After flowering, a seed box is formed. The seeds are brown. After the seeds ripen, the capsule opens with its lobes and looks like a star in appearance.

Caring for astrophytum at home

Lighting

The homeland of the origin of astrophytum suggests that the cactus needs regular bright lighting. It can also tolerate direct sunlight, but only for a short time. Mainly prefers bright, diffused light. The plant must be taught to hit the rays gradually, especially in the spring, otherwise the cactus can get serious burns.

Temperature

In summer, astrophytum will feel comfortable at sufficiently high ambient temperatures - up to 28 degrees. Starting in autumn, the temperature is gradually lowered to 12 degrees. In winter, when astrophytum is at rest, the temperature should not be more than 12 degrees.

Air humidity

A distinctive feature of cacti is that they do not need high humidity. Therefore, astrophytum is optimal for growing in apartments and private houses.

Watering

Astrophytum is rarely watered in spring and summer. It is necessary to wait until the substrate in the pot is completely dry to the very bottom. Only after that, the astrophytum can be watered using the bottom watering method so that water does not fall on the surface of the plant. The lime contained in the water leads to clogging of the stomata of the plant, due to which its respiration is impaired and the tissues die off.

Astrophytum is watered in the morning when the sun is shining brightly. If it is too hot in the room, then it is worthwhile to wait with watering, since at this time the plant begins a dormant period. In autumn and winter, the cactus is kept in a cool room. At this time, you do not need to water it at all.

The soil

For planting astrophytum, you can use a cactus mix purchased from a specialist store. It would be nice to add charcoal and lime chips to it.

Top dressing and fertilizers

In the spring-summer period, astrophytum needs regular feeding about once a month. A special fertilizer for cacti is diluted in water at a dose that is half that indicated in the instructions on the package. In winter and autumn, the plant is dormant, so there is no need to fertilize it.

Transfer

A cactus needs to be transplanted extremely rarely and only if the root system has grown strongly and completely entangled the entire earthen lump. The pot for the transplant is chosen a little larger. The drainage in the container should be both top and bottom. Expanded clay can be placed at the bottom, and decorated with stones on top. The upper drainage layer will not allow the cactus neck to come into contact with damp ground, which will prevent the plant from rotting.

During transplanting, it is important not to deepen the neck of the plant too much. Otherwise, over time, it will rot from contact with water and the plant will die. Astrophytum is transplanted by the transshipment method, when the old soil is not shaken off from the roots, but the total mass is planted in a new pot. After the plant is placed in a new pot, its first watering can be carried out only after a week in case the roots were disturbed during transplantation. During this time, they will dry out and will not start to rot from contact with water.

Reproduction of astrophytum

For astrophytums, the only way of reproduction is characteristic - with the help of seeds. The seeds are soaked in a light pink solution of potassium permanganate for 7 minutes, and then sown in a pre-prepared substrate, consisting of equal parts of charcoal, river sand and leafy earth. From above, the pot is covered with glass or foil and regularly ventilated and moistened.

They contain a greenhouse at a temperature of about 20 degrees. The first shoots will appear in a few days. It is important not to overmoisten the soil, otherwise small cacti will die.

Diseases and pests

Astrophytum is susceptible to damage by such pests as mealybug, scale insect, root bug.

Growing difficulties

Any external unfavorable changes in the plant can speak not of being damaged by pests, but of improper care.

  • Brownish spots on the surface of the stem - insufficient watering or watering with lime water.
  • Lack of growth - insufficient watering or excessive waterlogging of the soil in winter.
  • The wrinkled tip of the stem, at the base of the spots of soft rot - excessive waterlogging of the soil, especially in winter.

Therefore, when the first signs appear, it is important to adjust the conditions of keeping astrophytum as soon as possible.

Plants homeland

The homeland of this decorative culture is the subtropics and tropics of Central and South America. Here it is called fiery "tongue" or "flamingo". The flower can be found in the territory from Mexico to the north of Argentina and Monstera.

Astrophytum - gardening

Gardeners received a frost-resistant abutilon variety. Now abutilone is not only beautiful, but can withstand temperatures down to -12 ° C. Abutilon x santens blooms vigorously all summer. Its ornate bushes fill the gardens with genuine joy. This hybrid rightfully received the AGM award. A. Santens inherited and improved the properties of his parents A. vitifolium and A. Ohsen.

Abutilon grape-leaved - A. vitifolium


A. vitifolium - A. grape-leaved

The beginning of the creation of a new type of garden abutilon was the appearance in Europe of two frost-resistant species of abutilone, brought from Chile, in South America. The first was discovered A. vitifolium (A. grape-leaved), sometimes it is called "Sheep abutilon" (Corynabutilon). The leaves of the plant are similar in shape to the leaves of grapes, only they have a delicate edge. Large white, white-pink or pale violet-blue flowers are rounded, resembling a saucer up to 7 cm in diameter. Cultivation began in Dublin in 1836, and soon it became one of the most popular species as a garden plant. In 1984, several of its varieties won the prestigious AGM (Award of Garden Merit!).

Abutilon Ohsena - A. ochsenii

Almost simultaneously with the "grape-leaved" was discovered and Abutilon ochsenii (A. Ohsena). However, the plant appeared in Europe much later, it took a long 100 years before it came to Britain. Friendship helped. E.B. Anderson (E.B. Anderson) was in constant correspondence with his Chilean friend, who lived in the city of Valdivia, in southern Chile. In 1957, Anderson received a parcel of seeds from his friend. Among the seeds was "Oxen". The plant turned out to be even more resistant to frost: if A. grape-leaved can withstand temperatures up to -2 ºС, then A. Oxena can withstand temperatures up to -5 ºС. Unlike A. grape-leaved, the purple flowers of A. Oxen are smaller, and at the base of each petal there is a dark spot. In addition, the leaves are dark green and less pubescent. A. Oxena received the AGM award in 1962. Unfortunately, it is not grown everywhere, which, apparently, is associated with certain difficulties in reproduction.

Frost-resistant garden abutilon Santens

But, here we come to the main event! When gardeners had in their hands two such wonderful species as A. grape-leaved and A. Oxena, naturally, gardeners could not resist trying to cross them with each other and get something new, unique. Experiments were carried out in several flower farms, and the result was indeed obtained, but here's the paradox: the result was not received at all where it was expected.

Geoffrey Gorer was known in London as an anthropologist, but he was very interested in gardening, was an active member of the Royal Horticultural Society and regularly attended its meetings. In 1950, Geoffrey Gorer bought the Sunte House, a small 17th century mansion in Sussex, and dedicated himself to its garden.

Everyone was surprised when Jeffrey Gorer's younger brother, Richard, quit making music and went into gardening entirely. The motives were unclear, but it is possible that one of the reasons for this transition was the influence of his brother. However, it was Richard who became the gardening scientist. From under his pen, more than 20 books were published on flowers, bushes and trees, their properties and the traditions of their cultivation. The children of one of Richard's close friends called him somewhat disrespectfully “Old Weed” (“Old Weedy” is translated as “overgrown with weeds”, in relation to a person it means “lanky”). In his garden, overgrown with weeds, there were islands of land on which he grew his treasures. Children were in awe of his knowledge, but they noticed that it was difficult to get him to talk about anything else besides plants. They didn't even know about his previous musical career.

One day, Richard came to visit his brother. In Jeffrey's garden there were 2 types of abutilone - A. grape-leaved and A. Ohsen. Going out into the garden, Richard saw that a third had grown up next to two bushes. Nobody planted him. Where did he come from? Obviously, cross-pollination happened by accident and a beautiful baby was born. Christopher Brickell named it A. x suntense, after the place where the wonderful hybrid was first born.

Abutilone Garden Merit Award (AGM)

The new hybrid is vastly superior to its parents in all respects. The main characteristics are as follows: it grows quickly, reaching a height of 3m, the flowers appear in bunches, 2 or 3 pieces in each flowers are large, violet-blue, without a spot at the base, a short period of flower life is compensated by abundant flowering during all summer months, leaves are five-lobed, pubescent, soft to the touch, matte green on the front side and paler on the bottom, frost-resistant, tolerates temperatures down to -12 ° C. In 1967, in the greenhouse “Hiller”, a purposeful crossing of these species was carried out, which confirmed the line of relationship.

Abutilon x santens blooms vigorously all summer. Its ornate bushes fill the gardens with genuine joy. In 1984, this hybrid rightfully received the AGM award.
