A shrub three to six feet high, more or less tomentose-pubescent when young, at length glabrate throughout and somewhat glaucous. Leaves: thick, broadly elliptic or orbicular, very obtuse, and often truncate at the apex, rounded or subcordate at the base, coarsely dentate above the middle. Flowers: white, in short racemes, rather dense; petals five, oblan-ceolate, cuneate. Fruit: a globose pome, purple with a bloom, sweet.

This is the low pearly-flowered shrub which grows on the sandy banks and flats, and which the Indians call Saskatoon, for its sweet purple berries form a staple article of food with them during the months of July and August. It somewhat resembles the Western Choke Cherry, but its greenish-white blossoms are larger and have long narrow petals; also its leaves are oval, with flattened ends, and are very coarsely toothed above the middle, whereas those of the Western Choke Cherry are oblong, pointed, and finely toothed all round the edges. The bark of the little branches of the Serviceberry is reddish, and the young leaves are quite pale and downy underneath..
