Asistasia (lat. Asystasia), or asistasia, is a genus of flowering plants of the Acanthus family, which includes various sources from 20 to 70 species that grow in South Africa and Oceania, as well as in areas with a tropical climate in Asia. In culture, there are only two representatives of the genus.
Planting and care for azistasia
- Flowering: usually in spring or early summer.
- Lighting: in the morning - bright sunlight, in the afternoon - bright diffused light.
- Temperatures a: during the growing season - 20-25 ˚C, in winter - 12-18 ˚C.
- Watering: during the period of active growth - plentiful, after drying of the top layer of the substrate in the pot. During dormancy, water consumption is reduced, but the principle of irrigation remains the same: the top layer of the substrate between irrigations should dry out.
- Top dressing: from March to September twice a month with complex mineral fertilizers for flowering indoor plants. Since September, feeding is gradually stopped.
- Pruning and pinching: Azistasia is trimmed and pinched at the beginning of active growth to form a compact bush.
- Rest period: at home it is not pronounced, but the plant usually rests from October to February.
- Transplant: by transshipment as the pot becomes small.
- Reproduction: trimmed stems and apical cuttings.
- Pests: spider mites.
- Diseases: root rot.

Azistasia flower - description
In our latitudes, azistasia is grown exclusively as a houseplant. It is an evergreen shrub with erect shoots, reaching a height of one meter. The green leaves of azistasia, pointed to the apex and serrated at the edges, are attached to the stems with short petioles. Every year, part of the shoots of the plant dies, but the buds of renewal remain. Over time, the plant forms a semi-lignified trunk, and azistasia becomes a small tree with drooping branches.
Azistasia is grown mainly because of its small axillary tassels of flowers up to 5 cm in diameter, which resemble large bells with open and bent petals of white, cream, purple or gray-violet color, decorated with contrasting veins. The racemose inflorescence can reach a length of 12-20 cm.
Planting and care for azistasia
Conditions for growing azistasia
Azistasia is still poorly understood, but it can be said with confidence that it adapts well in room culture, and the cultivation of azistasia in the first place involves the creation of conditions necessary for normal growth and development. This thermophilic tropical guest prefers bright diffused light, but a small amount of direct sunlight will not harm her.
The optimum temperature for azistasia is 20-25 ºC in the summer and 12-18 in the winter. Protect the plant from drafts and temperature extremes that cause azistasia to lose leaves. The dormant period of the plant is weakly expressed; it usually passes from September to February.
Caring for azistasia at home
During active growth and flowering, azistasia should be watered abundantly as soon as the top layer of the substrate in the pot dries. At rest, watering is reduced. To moisten the substrate, use settled water at room temperature or slightly warmer. The plant is indifferent to air humidity and does not need to spray leaves.
Azistasia is fed with complex mineral fertilizers for flowering indoor plants. In the spring, as soon as the new growing season begins, top dressing is applied once or twice a month, and since September, fertilizer application is gradually stopped.
During the growing season, shoots grow strongly in azistasia, and, to form a compact bush, it is pruned and pruned. When it is better to cut off azistasia, you have to determine it yourself experimentally: in a room culture, this plant is new, so it is not known exactly when it lays flower buds. A pinch is needed so that azistasia is more bushy.
Azistasia is transplanted as necessary, when the pot becomes small for it. Since an adult plant has a well-developed root system, dishes for azistasia need wide and deep. The new container must be taken in diameter 2-3 cm more than the old one. The optimal composition of the soil for azistasia: turf and sheet earth and sand in a ratio of 2: 2: 1. A thick layer of drainage material must be laid to the bottom. Transplantation is best carried out by transshipment method.
Propagation of Azistasia
Azistasia is propagated by apical stem cuttings or stalk trimmings that remain after cutting the plant. Cuttings are easily rooted in water or a light substrate, consisting of equal parts of peat and sand with the addition of sphagnum. The planted cuttings are placed in a warm place, but they are not covered with a cap of polyethylene, and after the roots have grown back, the cuttings are planted in a pot with a soil mixture for an adult plant.
Pests and diseases of azistasia
Azistasia is resistant to diseases and pests, but in conditions of low humidity, spider mites can appear on it - sucking arachnids that feed on the plant sap. You can learn about their presence by whitish points on the leaves - places of punctures. Keep in mind that ticks multiply at a tremendous speed, and the appearance of a thin web on azistasia will be evidence that the plant is fully occupied, and you will have to fight long and hard with the tick. To prevent this, regularly inspect the plant, maintain normal air humidity in the room and wash azistasia from time to time in the shower, and at the first sign of uninvited guests treat the plant with an acaricidal preparation, Actellik , Fitoverm or Aktara , just in case .
With stagnation of water in the roots of azistasia, rot may develop, so be careful not to make such mistakes. If the problem still arises, you will have to remove the plant from the pot, remove rotten roots, treat the root system with a fungicide solution, transplant the plant into a fresh substrate and reconsider your attitude to watering.
Types and varieties of azistasia
Since azistasia appeared on our windowsills not so long ago, from time to time there is confusion in the question of what is considered a species and what is a variety or form of one or another species. To date, only two types of azistasia are grown in culture.
Beautiful asystasia (Asystasia bella)
- an evergreen shrub native to South Africa with ovate-oblong, pointed to the apex, short-leaved and finely serrated leaves along the edges and white, pink or lilac flowers with purple veins. This species has a popular form:
- net azistasia - a plant with a beautiful mesh pattern on the leaves, almost repeating their venation.
Asystasia gangetica (Asystasia gangetica)
or gangetic azistasia is widespread in tropical Asia and South Africa. Her flowers are most often white or cream, but there are purple. They are decorated with veins darker than the tone of the petals. The small-flowered form of the species is known, as well as the form with variegated foliage:
- varistate azistasia is a variety of Gangan azistasia with variegated leaves: green with white stripes and a border.
