Argyroderma is a succulent which belongs to family Aizoaceae. A sort such plants from the Cape Province of Africa, the Republic of South Africa and the desert of Peru. They prefer to grow on sandy and rocky soil, at the same time, to be saved from a strong heat, such plants are capable “to be dug” in the sand.
Called this sort of plants thus thanks to the not absolutely usual silvery color of its leaves. So, in translation from Latin of “argyrum” means “silver”, and “derma” is “skin”. Such a dwarfish succulent plant is blossoming and has external similarity to a stone. Prefer raise argir0oderma little groups. Is a part of the sheet socket 2 or 4 fleshy greenish-gray, half accrete leaflets which possess a semicircular form.
Leaving for argirodermy in house conditions
To each other such leaves are turned by flat surfaces. At the most part of types diameter of leaflets does not exceed 2–3 centimeters, and at the same time there is rather deep, distinctly expressed strip which divides sheet couple.
Very young leaflets grow directly between old which then wither. Short цветонос grows from boundaries of a sheet groove. In most cases, flowers are single and possess numerous petals. Three-centimetric diameter florets can be painted in yellow, white or pink color and they have strong external similarity to daisies.
Florets bisexual and to collect seeds, cross-pollination is required. Under natural conditions pollination of such succulent happens by means of insects. Not a rarity in culture accidental hybridization is considered. In this regard during blossoming different types and grades need to be separated somehow from each other. Pollination is required to be conducted independently by means of a brush.
Fruits ripen long enough, as a rule, till April or March of the next year. Fruits are the closed capsules which have a diameter about 0.9-1.2 centimeters, and they are formed by accretion of carpels. These capsules are divided into cells which there are from 8 to 28 pieces.
The ripened cells possess the mechanism of expansion of Kiel of lids at liquid influence. So, at that time when it is raining, there is an opening of lids, then the falling rain droplets with ease beat out the ripened seeds, and those, in turn, scatter on not really long distance from a maternal plant. At cultivation in room conditions, there are 2 ways of collecting seeds.
First, it is possible to knead capsules and to choose seeds. And secondly, these fruits should be lowered “headfirst” in the small capacity filled with water. After lids reveal, seeds will fall by a bottom. They should be taken out from water and to dry up in the shaded place.
Such plant needs bright lighting for the whole year.
In the summer the plant normally grows and develops at the room temperature. In winter time needs a cool from 12 to 15 degrees. At the same time surely you watch that in room 8 degrees were not colder.
It is quite adapted for life in the low humidity of air of city apartments.
How to water
Watering is made only during the intensive growth and blossoming. It is necessary to water through a pallet and only after the earth lump dries out completely. You watch that in a pallet there was no stagnation of liquid. Approximately from October to April, the argiroderma does not need to be watered at all. At this time leaflets can dry and strongly be wrinkled completely, but watering even in this case cannot be made.
Fertilizing should be carried out only to the time of formation of buds and also blossomings, at the same time weak solution of the fertilizer intended for cactuses is used.
Features of change
Change is carried out before the period of intensive growth, 1 time in 2 or 3 years begins. Suitable землесмесь consists of 2 parts of the sheet earth and 1 part of sand. After a change, the surface of the soil is powdered with a layer of coarse-grained sand. If desired it is possible to buy the soil for cactuses. Capacity for landing has to be low and wide. At its bottom, there have to be good drain holes. Also at the bottom of capacity do not forget to make a good drainage layer.
Ways of reproduction
It is possible to multiply, having divided the expanded group of plants in the course of change and also seeds. Seeding is recommended to be carried out in recent weeks February and the first ― March. In this case, the additional illumination will not be required, and till winter of plants will enough get stronger.
For crops, the soil for cactuses is used. On its surface, it is necessary to put seeds and to powder them with a thin layer of coarse-grained sand, at the same time the distance between them has to be not less than a half-centimeter. Capacity needs to be covered with glass or a film and to put to the warm place (20–25 degrees).
Within the first month of airing carry out 1 time a day on 1–2 minute. Then this procedure is carried out several times per day, and their duration has to be from 5 to 10 minutes. 8 weeks later after crops, the shelter is recommended to be cleaned at all. Watering is carried out by lowering a pot to the container with water before soaking of the soil.
It is necessary to choose a brightly lit place, but at the same time, direct beams of the sun should not be. The first seedlings will seem about a week later after crops, at the same time the general germination lasts from 30 to 40 days. Blossoming of very young plants is observed for 3 or 4 after crops.
At this dwarfish succulent at a couple of leaflets diameter can vary from 1 to 2 centimeters. Fleshy leaves which grew together in the basis have the semi-ovoid form, at the same time the party of accretion is flat. The emergence of a floret comes from the boundaries of a sheet groove. Externally it is similar to a daisy and possesses glossy petals saturated – yellow color, whitish stamens, and at the same time boots at it a yellow color.
Dwarfish succulent. From 2 to 4 juicy leaflets of a cylindrical form which can be painted in various shades from greenish-gray to lime-green are a part of sockets. Flowers single with a short peduncle and they grow between the top leaflets. The diameter of a floret can vary from 1 to 3 centimeters, and at the same time, it can be painted in a yellow, white or pink color shade.
Dwarfish succulent. The diameter of each sheet socket can reach 2.5-3 centimeters, at the same time the fleshy leaflets having rather big thickness are their part. To each other, they are turned by flat surfaces, and I can be painted in greenish-blue or grayish-blue color. Happens that on a surface there is also a pretty point.
Grows from boundaries of a sheet groove short цветонос which bears a flower externally similar to chamomile. Its diameter is about 4 centimeters, and a color ― pink. On the end of blossoming old leaflets begin to die off, and they are replaced by very young.
