wild cherry Identification (Prunus avium)

Use these quick checks to judge whether a tree is Prunus avium.

• Leaves are simple, alternate, and oval with a pointed tip and finely toothed edges, usually 3 to 6 inches (8 to 15 cm) long.
• A pair of small red glands often sits on the leaf stalk near the blade.
• Flowers are white, with 5 petals, carried in small clusters on long stalks.
• Fruits are round cherries about 1/2 to 1 inch (1.3 to 2.5 cm) across, hanging singly or in pairs.

Bark can also help: mature trunks often show shiny reddish-brown bands with horizontal lines.

Prunus avium shows clear visual changes from sapling structure to flowers and fruit.

• Young plant: Young plants are narrow and upright, with a straight leader, smooth bark, and relatively large simple leaves on slender, lightly branched stems.
• Mature plant: Mature trees develop a broader crown and stronger lateral branching; the trunk thickens, and bark becomes shiny with obvious horizontal bands and peeling rings.
• Flowering stage: Flowering branches carry clusters of white five-petaled blossoms, each about 1 inch (2.5 cm) across, exposing the branch framework before fruit forms.
• Fruiting stage: Fruiting stage is marked by hanging pairs or small clusters of rounded cherries that turn deep red to dark purple-black, visually replacing flowers.

A few cultivated forms of Prunus avium are easy to separate by flower structure or crown shape.

• 'Plena': Double flowering cherry with many-petaled white blossoms, unlike the typical single 5-petaled flowers.
• 'Pendula': Weeping form with strongly drooping branches that create a cascading crown instead of the usual upright to spreading canopy.
• 'Fastigiata': Narrow, columnar habit with steeply ascending branches; it stays much slimmer than the broad crown of the species.

In spring, Prunus avium is often easiest to spot when clusters of white flowers open on mostly bare branches or alongside newly emerging leaves. Fresh spring foliage is bright green and finely toothed. By early to mid-summer, red to dark red cherries become visible. In fall, leaves turn yellow to orange before dropping, which exposes the winter branching pattern and smooth bark.

Several cherries are regularly mistaken for Prunus avium.

Prunus avium is native to Europe, western Asia, and parts of North Africa. It occurs naturally from lowlands into lower mountain zones, often in temperate regions rather than Mediterranean scrub. In the wild it is most often found in mixed deciduous woodland, forest edges, hedgerows, and clearings. Finding a cherry tree in these inland woodland-edge habitats helps separate it from species more typical of wetlands, coastal sites, or dry open grassland.

• Seeds and wilted leaves: The pits (seeds) and wilted leaves contain cyanogenic compounds. Risk is from ingestion by humans and pets, especially dogs, cats, horses, and livestock.
• Fruit flesh: The cherry flesh is not the main concern, but swallowing pits creates the hazard because the seed inside is the toxic part for humans and pets.
