This shrub has deciduous leaves native to central-southern Asia, which reaches 150-200 cm in height.
The thin stems have erect habit, branch abundantly with the passing of the years; they have green bark, which becomes red-brown in winter, when the plant has already lost all its leaves.
The leaves are oval, or lanceolate, light green; there are numerous cultivars, even with variegated leaves, such as C. alba elegantissima; in autumn they show a bright red or orange color.
In late spring they produce clusters of small white-cream flowers, followed by white or bluish berries. THE cornus alba they produce numerous basal suckers, which often have a more intense coloring than the older stems, so it is advisable not to eradicate them all.

Cultivation is not demanding and is within everyone's reach, thanks to the excellent resistance qualities of this variety.

It can easily withstand short periods of drought, especially if the plant has been planted for some years. In spring it is good to bury organic fertilizer at the foot of the plant. With young specimens it is appropriate to provide at least one weekly watering, while for adult plants it is not necessary as they are satisfied with rainwater.

There are many different varieties of this plant with some differences in growth and flowers, but with a very similar structure that lends itself to the creation of cuttings.

In spring it is also possible to propagate the cornus alba by sowing, using the seeds of the previous year.
