Jacquard Botanical Description
Jacaranda leaves are opposite, pinnately dissected, fern-shaped.
Jacaranda inflorescence - panicle, apical or axillary. The flowers are tubular, always bisexual, five-membered and zygomorphic, blue or lilac, there are also species with white and purple flowers.
Jacquard care at home
Jacaranda needs good lighting, tolerates a certain amount of direct sunlight. A number of authors recommend direct sunlight for jacaranda for 2-3 hours a day. Suitable for cultivation in the western and eastern windows. At the southern windows in the period from spring to autumn should shade the plant from the midday sun.
After a long cloudy weather, a recently bought plant or plant should be accustomed to direct sunlight gradually, in order to avoid sunburn. One-sided lighting of the jacaranda causes deformation of the crown.
The optimum temperature for keeping jacaranda from spring to autumn is 22-24 ° C. From October to spring it is permissible to slightly lower the temperature to 17-19 ° C, not lower than 15 ° C.
The jacaranda is watered regularly all year round with soft, settled water, as the top layer of the substrate dries. The plant changes foliage in winter or spring - discards the old and dissolves the new one. During this period, watering of jacarandas should be limited, but the earthen coma should not be allowed to dry.
Jacaranda grows in tropical rainforests, therefore, prefers high humidity. It is recommended that the plant be sprayed daily with lukewarm, soft, settled water; you can also place a container with the plant on a pallet filled with wet expanded clay or peat.
In the spring-summer period, the jacaranda is fed once every three to four weeks with complex mineral fertilizer. In autumn and winter, the plant is not fed. Also, do not fertilize during the dropping of leaves.
In winter or early spring, the jacaranda drops its leaves even when it is light. Leaves reappear in spring. Adult specimens begin to lose leaves from below, while becoming less effective. During this dormant period, it is kept in a bright place at a temperature of 17-19 ° C.
To form a compact crown, spring ends should be pinched at the plant regularly in spring. Since jacaranda is characterized by relatively strong growth, it should be borne in mind that the trunk can be exposed.
Possible difficulties growing jacaranda
In winter or spring, foliage flies around the jacaranda - this is a natural process of replacing foliage.
Damaged: spider mite, scale insect, whitefly, aphids.
The jacaranda is transplanted in the spring, as necessary, when the roots fill the entire space of the pot. The following mixture is suitable as a substrate: light-sod land (2 parts), humus land (1 part), peat (1 part), sand (1 part).
A substrate consisting of 1 part of turf, 2 parts of leafy soil, 1 part of peat, 1 part of humus soil, 0.5 part of sand is also suitable. At the bottom of the pot provide a good layer of drainage.
Plants are propagated by seeds and cuttings.
Growing jacaranda from seeds
Seed propagation is produced in the spring. Before sowing the seeds, they are soaked - put in a warm place wrapped in a damp cloth - for a day. Planted at a depth of about 1 cm, watered.
The seeds of jacaranda emerge in warm (22-25 ° C) conditions of a small plate for 14-20 days.
When jacaranda shoots appear, the amount of light is increased, the seedlings are transferred to a place with bright diffused light. Seedlings are planted in 1 copy. in 7 cm pots. The substrate is composed of humus soil - 1 hour, peat - 1 hour, light turf - 2 hours and sand - 1 hour. Subsequently, the plants are transferred to 9- and 11-centimeter pots.
From late spring to mid-summer, jacaranda can be propagated by cuttings.
Jacaranda is a source of fairly valuable wood - rosewood, rosewood (French palissandre), the wood of some South American species of jacaranda, in garlic Jacaranda filicifolia. The core of the wood is dark red to chocolate brown with a purple tint, sapwood is light yellow.
The rosewood tree is heavy, durable, well polished, and is used in the manufacture of expensive furniture, musical instruments, colored flooring, and turning products.
Sometimes a rosewood is called dalbergia wood (the family of moths) and some other trees. To simulate a rosewood tree, birch, maple, alder wood is used.
October-November in Australia is the end of the school year, the time for exams. So the flowering of jacaranda is closely related to student culture. In youth slang, a jacaranda is called an examination tree. There is, for example, a sign - if the jacaranda panicle falls on your head, then you will pass all the exams successfully. Who knows, maybe, in part, and therefore jacaranda is grown in large quantities. This plant promises good luck.
However, this is for someone like. There are different opinions on this subject. Some students call the jacaranda "lilac panic." It is believed that until the jacaranda blooms, it is too early to start preparing for exams, and when it blooms, it is too late.
At the same time, it is obvious that the existence of jacaranda is associated not only with student life in Australia. The Australians have some completely deep relationship with this plant. For example, it is customary to plant a jacaranda after the birth of a child. And in Brisbane, in the years 30-40, seedlings were even officially issued in maternity hospitals.
And in the city of Grafton every year in October the Jacaranda Festival is held, with a street procession and a number of other events.
Many species are grown as ornamental plants - especially the Jacaranda mimosifolia species.
Some species of jacaranda are grown as houseplants. Indoor cultivate only young plants.
