Sophora - Sophora davidii


The Sophora davidii is a medium-sized or large deciduous tree, originating from Asia. The adult specimens of sofora can reach 5-7 m in height; the trunk is erect, densely branched, and the crown is rounded, with a diameter equal to the height of the plant. The bark is dark, gray-brown, smooth; the branches are olive green. The leaves are alternate, pinnate, divided into 10-15 oval, shiny, dark green leaves; before falling in autumn they become yellow. In late spring it produces numerous bunches of white and yellow flowers, quite fragrant, followed by long green pods which contain the seeds and which often remain on the plant for a long time.
The "pendula" cultivar has thin and pendulous branches, with a very prostrate habit, which sometimes touch the ground with their tips.


The Sophora davidii prefers sunny positions and is planted as a single specimen, since it requires a lot of light and a good air exchange. It does not fear the cold, even if the young specimens could be slightly damaged by particularly cold winters.
The sofora is also suitable for cultivation in marine localities, since it is well suited to the temperate climate, while resisting cold temperatures, but it is a genus that does not like strong winds very much.


This kind of trees does not need large amounts of water, and it tolerates drought very well. It also bears the winds, as long as they are not too strong, and pollution, for this reason the Sophora davidii is very suitable to be planted along city streets.
The youngest specimens of this variety require special care and attention, given their greater fragility, and, for them, it is good to provide more regular watering, while the adult sofora trees can be satisfied with rainfall.


The sofora prefers loose, deep and well-drained soils; before planting it, it is good to prepare the soil by fattening it with a good amount of mature manure, which guarantees the right amount of nutrition to the plant. It is good to check that the drainage of the soil is sufficient as the water stagnation could compromise the health of this kind of trees.


The multiplication of Sophora davidii occurs by cuttings or by seed, given the ease with which the numerous seeds produced can be found. The new plants obtained must be cultivated for a few years in a cold greenhouse before they can be planted, so that they acquire strength and can be transplanted without problems.
