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.
