juneberry Identification (Amelanchier × lamarckii)

Check the overall form and a few clear structures before deciding on Amelanchier × lamarckii.

• Usually a large multi-stem shrub or small tree with an upright, open crown.
• Leaves are simple, oval to elliptic, about 2-4 inches (5-10 cm) long, with fine toothed edges.
• Leaf undersides often look softly hairy, especially along the veins and margins.
• Flowers are starry and white, with 5 narrow petals held in loose clusters.
• Fruits are small, round, and dark purple to black when visible.

Use several of these traits together, especially the leaf shape, flower form, and multi-stem habit.

Amelanchier × lamarckii shows clear visual shifts in habit, flowering, and fruit display with age.

• Young plant: Usually a slender, upright shrub with several thin stems; leaves are smaller and the branching is still open and sparse.
• Mature plant: Develops into a broad, layered large shrub or small tree, often 10–20 feet (3–6 m) tall, with a denser crown and stronger main stems.
• Flowering stage: Bare or lightly leafing branches carry drooping clusters of narrow-petaled white flowers, making the plant look airier than in later leafy stages.
• Fruiting stage: Small round pomes replace the flowers in hanging clusters, shifting the outline from pale and filigreed to dotted with darker, obvious fruit.

In spring, bronze-tinted young leaves open with clusters of white, starry flowers, making Amelanchier × lamarckii especially distinctive. By early summer, the flowers give way to small berries that ripen from red to deep purple-black. Fall brings one of the clearest clues: foliage turns vivid orange, red, and copper before leaf drop. In winter, the fine branching and smooth gray bark are easier to see.

Several small flowering trees can be mistaken for juneberry.
