Celastrus orbiculatus or celastro is a vigorous deciduous climbing plant native to eastern Asia. This climber grows rapidly, clinging to the supports and growing up to 5-6 meters in length. The stems are dark, semi-woody or woody; the leaves are dark green, rounded, with a finely serrated edge, waxy.
In spring it produces numerous clusters of greenish flowers, which bloom at the leaf axil; in summer the flowers give way to decorative green or yellow woody berries, which, as they ripen, tend to split, revealing the fleshy berries they contain, of a bright red color.
Usually, this type of plant also grows spontaneously, but it can be grown with satisfaction and is often used in flower arrangements, thanks to its aesthetic appeal.
It is advisable to use pruning to prevent it from growing excessively, since it is a rather invasive climber.
The Celastrus orbiculatus is a rustic and resistant shrub that prefers sunny positions, but that manages to grow even in shady or half-shaded areas. The celastro is a resistant plant and bears very well the winter cold, but not the action of the wind, therefore it is advisable to place it in a place sheltered from the strong winds.
Even during the coldest winters it can withstand without the need for special protection.
As for the water supply, it is advisable to water the skin light sporadically, only in periods of prolonged drought; normally the plant is satisfied with seasonal rains and is able to find the necessary water thanks to its developed root system.
Check that at the base of the plant dangerous water stagnations do not form, which could compromise their health.
In spring bury a mature organic fertilizer at the foot of the plant.
Celastrus orbiculatus prefers loose, well-drained soils, rich in organic matter, but, being a rustic plant, it often grows even in unfavorable, poor and dry soils. The ideal soil for its development is the non-calcareous type.
The multiplication of Celastrus orbiculatus occurs with ease by seed in spring and the celastrous plant also tends to autoseminarsi. If desired, it can also be propagated by cutting a portion of the roots: fleshy stolons from which suckers often grow. The portions practiced can be placed directly in the home. In the autumn period it can be propagated by offshoot, making the new seedlings well rooted, before finally planting them.
The seeds can also be used in November, placing them in special containers placed in a cold greenhouse, where they can germinate in tranquility. Germination occurs after four months.
