About

Cornus kousa 'Blue Shadow' is a robust shrub or small tree that can reach heights of up to 9 meters. Its leaves exhibit a rich blue-green luster. In summer, it produces large, creamy-white bracts that elegantly encircle a central group of flowers. As autumn approaches, the tree develops strawberry-like fruits, while the foliage transforms to shades of red, orange, and purple.

About the genus

Cornus includes a variety of deciduous shrubs and trees, as well as prostrate, woody perennials, some featuring vibrant young stems. The small flowers appear in compact clusters, occasionally accompanied by prominent bracts. Several species display attractive foliage in the fall.
