description

Ward's cotoneaster is an evergreen, up to 3 meter high shrub with stalk-round, initially white felt and later balding and then brown and shiny branches. The leaves are divided into a petiole and a leaf blade. The petiole is 3 to 4 millimeters long and densely tomentose. The stipules are linear, 4 to 6 millimeters long and sparsely hairy. The leaf blade is leathery, simple, oval or ovate, 2.5 to 4 inches long and 1.5 to 2 inches wide, pointed and with a round or broadly wedge-shaped base. 5 or 6 leaf veins are formed. The upper side of the leaf is shiny dark green, initially finely hairy and later glabrous, with sunken leaf veins; the underside is dense silver-gray tomentose hairs with prominent leaf veins.

The inflorescences are panicles of 9 to 15 flowers with white tomentose hairy inflorescence spindles. The bracts are reddish brown, linear, 4 to 5 millimeters long and sparsely hairy. The flower stalks are hairy white tomentose and 1 to 3 millimeters long. The flowers are 6 to 7 millimeters in diameter. The flower cup is bell-shaped and has thick white felted hair on the outside. The sepals are triangular and pointed. The petals stand erect, they are white and slightly reddish in color, broadly obovate or rounded, 3 to 4 millimeters long and 2.5 to 3.5 millimeters wide, with an incised leaf edge, blunt tip and a short nailed base. The approximately 20 stamens are slightly shorter than the petals. The tip of the ovary is hairy white. The usually two to rarely four free-standing styles are slightly shorter or the same length as the stamens. The orange-red, obovate fruits are 8 to 9 millimeters in diameter. Usually two pips are formed per fruit. Ward's cotoneaster flowers from May to June, the fruits ripen from September to October.

Occurrence and location requirements

The natural range is in the southeast of the Tibet Autonomous Region in China. Ward's cotoneaster grows in dry forests and steppes at an altitude of 3000 to 4000 meters on moderately dry to fresh, slightly acidic to alkaline, sandy-loamy to loamy, nutrient-rich soils in sunny to light-shaded locations. The species loves warmth and is usually frost hardy .
