About

Cotoneaster dielsianus is an upright shrub that can reach heights of approximately 2.5 meters. Its slender branches arch gracefully, creating a distinctive form. The dark green leaves feature subtly impressed veins and have a soft, grey or greenish texture on their undersides. In autumn, the foliage transforms to a vibrant red. During the summer, this shrub produces clusters of flowers that are white with a hint of pink. These blooms give way to glossy red berries, adding visual interest to the plant.

About the genus
