Juneberry
Amelanchier lamarckii
A large deciduous shrub or small multi-stemmed tree characterized by abundant clusters of star-shaped white flowers appearing alongside emerging bronze-tinted leaves in spring.
- Light
- Full sun to partial shade, requiring at least 6 hours of direct sunlight daily for optimal flowering.
- Water
- Moderate water needs; water deeply during dry spells, allowing the top layer of soil to dry between waterings. Highly drought-tolerant once fully established.
- Growth
- Perennial multi-stemmed shrub or small tree growing up to 15 to 25 feet in height with a moderate growth rate.
Care instructions
Plant in full sun to partial shade in well-draining, moderately fertile soil. Water regularly during establishment and provide mulch to retain moisture. Prune lightly after flowering to maintain shape.
