The Canadian snowball ( Viburnum lentago ), also known as the sheepberry , is a large shrub or small tree native to eastern North America, where it is native to both the United States and Canada.
description
The Canadian snowball grows as a deciduous, upright shrub or a tree up to 10 meters high. Annual branches are covered with brown shield hair. The leaves are divided into a petiole and a leaf blade. The petiole is 1 to 2.5 inches long and has a more or less wide, wavy winged edge. Especially the underside can be covered with brown shield hair. The leaf blade is simple, ovate to elliptical-obovate, 5 to 10 centimeters long and pointed. The leaf base is broadly wedge-shaped or rounded, the leaf margin finely but clearly serrated. The upper side of the leaf is glossy light green, the underside is lighter than the upper side. The leaves turn vivid red-brown in autumn.
The flowers are creamy white, about 6 millimeters wide and pleasantly fragrant. They grow in terminal, sessile, mostly four-pointed, rarely three or five-pointed panicles with diameters of up to 10 centimeters. The fruits are ellipsoidal, 1.2 to 1.5 inches long, ripe blue-black and frosted. The species blooms in May and June.
The number of chromosomes is 2n = 18.

The distribution area is thus in the warm temperate climate of eastern North America, it is assigned to winter hardiness zone 5b with mean annual minimum temperatures between −26.0 ° and −23.4 ° Celsius (−15 to −10 ° Fahrenheit ). The species grows as floodplain or riparian wood on moderately dry, fresh to moist, neutral to alkaline, very nutrient-rich, sandy-gravelly soils in partially shaded, cool to cold locations. It is frost hardy .
