Legume family, subfamily Caesalpiniaceae. Homeland of Madagascar, South Africa, Argentina, India. About 20 species are widespread in nature.

  • Royal Delonix Delonix regia is a deciduous branched tree, reaching 10-15 m in nature in nature and about the same spreading crown. The bark is thin gray in color, very beautiful from the point of view of a bonsaist. The leaves are bright green, double-pinnate, up to 50 cm long. Each leaf is divided into 20-30 pairs of leaves, each of which, in turn, is divided into 10-20 pairs of oval leaves. Petioles are much shorter than leaves. With the onset of darkness, the leaves fold and droop. By the appearance of the leaves, delonix resembles an acacia. The flowers are large, zygomorphic, bisexual, collected in multi-flowered racemose inflorescences, apical and axillary. Four petals of the same scarlet or salmon color, 5-8 cm long. The upper, fifth petal (designed to attract insects to cross-pollination) is distinguished by color - bright yellow or white,speckled. The stamens are shorter than the petals. Sepals are also brightly colored. The seed pods are truly gigantic, they can be 60-80 cm long, dark brown in color. Each pod carries 20-40 seeds of an oblong shape, 2 cm long. Below photo: new
  • Delonix dwarf Delonix pumila is a caudex plant, native to Madagascar, reaching 1.5-3 m in height, and in a trunk girth of about 40 cm, a crown span of 3-5 m.The bark is gray, feathery leaves, each leaf is broadly oval, on a very short petiole. The surface of the leaves is dull green, the flowers are very large, with cream petals, the fifth petal is yellowish. The stamens are almost twice as long as the petals, drooping, with bright anthers.

Delonix dwarf, like Delonix royal, can bloom at home with good care, it has a particularly beneficial effect on flowering for 3-4 months of a cool dormant period.

Delonix is ​​a greenhouse tub plant, it requires a lot of space, if you do not form it like a bonsai (it is well formed by pruning, easily splices trunks), the span of branches in a 2-3 year old bush reaches more than 1 m.

Delonix care

Temperature: usual in summer, grows well in a wide range from 18 to 30 ° С, but in winter it prefers coolness within 10-12 ° С, with a dry content. During the dormant period, delonix sheds partially or completely the leaves, does not tolerate the heating season well, it can be very depleted and die. Under natural conditions, Delonix tolerates very low temperatures up to 0-1 ° C, in a pot culture this is unacceptable, but plants older than two years with a good root system can safely winter with an experienced grower (who knows how to insulate the pot and not overmoisten the soil) at +4.. + 6 ° С on the balcony or loggia.

By the way, in the summer, during the hottest time, delonix stops growing - it has a short period of rest, when the heat subsides, a new wave of growth begins, it continues until October

Lighting: like all legumes, prefers a bright, sunny place. Shading will be required on a sunny summer afternoon on the south window, after gradual accustoming, you can put it out on the street, on the balcony, on the veranda - for full lighting.

Watering: plentiful in spring and summer, the soil should dry well for the next watering in the upper half of the pot. In winter, watering is very limited, depending on the temperature. Delonix is ​​distinguished by good drought resistance, but does not tolerate prolonged drying out in the heat, the leaves turn yellow and fly around; stagnation of water in the roots categorically does not tolerate, especially with a cold snap.

Top dressing: from March to September, alternating complex fertilizers for decorative leafy plants with fertilizers for decorative flowering plants. Delonix is ​​responsive to transplanting into humus-rich soil. After the transplant, they do not feed for 2 months, then every two weeks can be fed. If you do not transplant, you can feed with bulk fertilizer "Giant" (quantity according to the instructions).

Air humidity: Royal Delonix loves high air humidity, in the optimal version 55-70%, it can be sprayed. If it is very hot and stuffy in summer, place the pot on a wide tray with damp sphagnum moss.

Transfer: annually in the spring. Soil mixture: 2 parts of leafy soil, 2 parts of turf, 1 part of very coarse river sand or small pebbles (4-5 mm). A good drainage to the bottom of the pot can be made from pieces of styrofoam. Delonix is ​​undemanding to soil acidity, in nature it grows on soils in the pH ranges from 4.5 to 7, but alkalization of the soil should be avoided so as not to disrupt the assimilation of some nutrients in the soil.

Formation of Delonix

Delonix tolerates pruning well, therefore it is often used as a potency, forming like a miniature tree in a bowl. It also tolerates pruning of the root system, if it becomes necessary to adjust its ratio with the aerial part. In nature, the shape of the crown of Delonix trees is not vertical, like in birches, but horizontal, like in acacias. Most Suitable African Bonsai Styles:

  • bushveld style bonsai (flat top)
  • pierneef style or open-umbrella (umbrella-shaped)

Delonix grows quickly and vigorously, the shoot growing from the seed needs to be pinched, as two leaves will grow, but at first it is reluctant to branch, the problem is that pruning and pinching often leads not to branching, but to the development of a new shoot, but in the singular.

In this case, instead of pruning, you need to do this: when the shoot grows to a certain length, bend it down with the top of the head and fix it in this position (use a soft braided wire or woolen threads), the growth point at the bottom will stop development, a new growth point is activated to replace it, the one that will be lower on the stem, but higher towards the sun.

Reproduction

Delonix propagates by stem cuttings and seeds. Reproduction by cuttings is difficult; for rooting, the apical semi-lignified cuttings are cut off in early summer. Rooted in water or wet vermiculite, heated at about 25-28 ° C, good lighting and high humidity (in a mini-plate or seal in a zip bag).

Seeds can be purchased at a flower shop, choose the freshest - they remain viable for 2 years (see packing date), there are usually 3 seeds in one package. Sow at any time of the year. Seeds are oblong, large - 20-25 mm long, with a hard shell. They need to be stratified - carefully filed with a file, or pricked with a needle, then soak in stimulants for a day. You can use drugs Narcissus, Zircon, Rostock.

Another way to prepare Delonix seeds:

First, they are dipped in boiling water for 2 minutes. After this time, add cold water so that the water is hot, hand-friendly. And leave until the water cools down. After a day, the seeds are taken out of the water (by that time the skin will wrinkle and soften, it is not necessary to remove it), and planted in a mixture of peat and vermiculite, or peat and sand in equal parts. With this method, the seeds do not need to be filed.

Sowing in moist, loose soil, consisting of 1 part of universal peat soil and coarse river sand (washed from dust). For sowing, take enough pots with a volume of about 350 ml. Delonix seeds require oxygen access during germination, so they are not buried deep in the ground (soil layer is about 2 mm). Seeds germinate at a temperature of 25-27 ° C within 10 to 40 days. Keep the soil moderately moist while waiting. As soon as the sprouts appear, make sure that there is enough light, if sown in winter or autumn, place a phyto-lamp or LED bulbs above the pots.

By the way, under natural conditions, delonix multiplies by seeds, when they, being eaten by animals, without being digested, fall into the ground with feces. The warm and humid environment of the intestines of a cow or pig is a good preparation for the seeds of many types of Delonix.
