Cornaceae

Cornus kousa Kousa dogwood

Starts as a shrub and grows into a multiple-stemmed tree. Grows in the wild in the mountain forests of China, Japan and Korea. Width of the crown circa 4 - 5 m. The growth is slow, especially when maturing. The leaf is dark green and slightly curved. The underside is blue green and a little bit hairy: the autumn colouring has yellow and scarlet red hues. Each head has inconspicuous flowers and has 4, circa 8 cm large, bracts that are creamy white to bright white in colour. In full bloom particularly decorative. The red, strawberry-like fruits are circa 2 cm across and have stalks that are 4 cm long and red coloured. The plant is shallow rooting with a fibrous root system. Requires a rich soil with a high humus content. Tolerates more drought and is slightly stronger than C. florida. There are several good cultivars, usually selected from the species chinensis.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from November 2024.
