Evergreen species are not cold-hardy in Ohio and will not be discussed. Twigs have a bitter, almond taste. Leaves are alternate and toothed. Flowers are perfect and often showy.
Fruit is a drupe and usually has a single seed.
A close examination of the twig will show a small branch stub at the end. Glands on petioles are often lacking, even on young growth. Twigs are glabrous. Flowers are white, and fruit is red or yellowish. Terminal buds are present.
