description

Branches with stalked, simple leaves and five-fold flowers with radial symmetry in early June.

The sand cherry grows as a small shrub that usually reaches heights of 10 to 40 centimeters, in rare cases up to 180 centimeters. It forms dense genetes , which are connected to one another by their root system. The alternate leaves arranged on the branches are divided into a petiole and a leaf blade. The simple, leathery leaf blades are 4 to 7 centimeters long and narrow-elliptical with a slightly serrated edge.

Two to four flowers stand together in bunches. The hermaphroditic flowers have a diameter of 15 to 25 millimeters and are radially symmetrical and five-fold with a double flower envelope . There are five sepals . The five free petals are white. There are 25 to 30 stamens present.

In late summer, when ripe, the sand cherry bears dark red to dark purple colored stone fruits with a diameter of 13 to 15 millimeters.

The number of chromosomes is 2n = 16.

distribution

The sand cherry is widespread in the northern half of the United States and eastern Canada . It can be found from Quebec and Newfoundland , south to Tennessee and Arkansas, and west to Utah , Montana, and Saskatchewan .
