Koelreuteria Paniculata


The Koelreuteria Paniculata is a medium-sized, deciduous tree originating from Asia. It has an erect trunk, often multiple, and develops a dense crown, untidy in young specimens, rounded in adult trees; the bark is light brown in color, generally furrowed by shallow wrinkles; the leaves are composed, imparipinnate, constituted by 7-15 oval leaflets, with serrated margin, of dark green color, they become yellow in autumn, before falling; the new leaves in spring have a bronze color. Between August and September it produces very showy pendulous racemes, in the shape of panicles, made up of bracts of a purple-red color, among which bloom small white flowers; during the first autumn months the flowers are followed by fruits, brown capsules, similar to small lanterns, with a paper consistency, which contain some dark seeds. A fairly fast growing tree, it reaches fifteen meters in height.


Speaking of which is the best possible exposure for Koelreuteria Paniculata plants, it is good to know that the koelreuteries are cultivated in a very sunny position, while well tolerating the semi-shady positions; in general the adult specimens do not fear the cold, but it is good to place very young trees in a place sheltered from the wind. Resistance to air pollution makes these trees very suitable for city parks.
It can easily withstand hot and muggy summers, while if these are moist and short, problems can arise and the plant can present the onset of fungal diseases.
Late frosts can cause serious problems, especially on the younger plains of Koelreuteria Paniculata.

These are trees that prefer loose soils, very well drained, deep and rich in humus; actually though the koelreuteria, being rustic and resistant, it adapts to any type of soil, even to the common garden soil. It is good, however, for the best development, that the soil allows proper water drainage.Multiplication

it propagates by seed, in spring, or by semi-woody or root cutting.
The multiplication of this type of plant can take place immediately after harvesting the seeds, planting them in a cold greenhouse. If the sowing takes place starting from the preserved seeds, they should be left to soak in hot water 24 hours before the operation. For the first winter, the seedbeds must be kept sheltered inside a greenhouse and then put in place. Newly planted plants must be protected with greater care during the winter season, using appropriate mulching to preserve the root system.
