The Story

Plant Bio

Amelanchier lamarckii is a small, multi-stemmed deciduous tree or large shrub offering exceptional four-season interest. It features clouds of white, star-shaped flowers in spring, followed by edible berries, brilliant fall color, and elegant winter structure. This species is particularly noted for its graceful, open habit and coppery-pink new leaves that emerge with the flowers, creating a beautiful two-toned effect. It has received the prestigious RHS Award of Garden Merit.

Uses & Benefits:

Amelanchier lamarckii is a premier four-season ornamental. It offers delicate spring flowers, lush summer foliage, fiery autumn color, and a fine-textured, silvery-gray branching structure that is beautiful in winter.

The small, sweet, blueberry-like fruits are edible and can be used in pies, jams, and jellies, or eaten fresh. The tree's modest size makes it suitable for smaller landscapes and urban settings.

It is an ecological powerhouse, providing early spring nectar for pollinators. The summer berries are a favorite food for over 40 species of birds, and the plant serves as a host for several butterfly species.

Planting

How to Grow

Choose a site with good air circulation to deter disease.
Dig a hole two to three times the width of the root ball.
Place the tree in the hole, ensuring the root flare is at soil level.
Backfill with the original soil, breaking up any large clumps.
Water deeply to settle the soil around the roots.
Apply a layer of mulch, keeping it away from the trunk.

Pro Tip

Provide consistent moisture after planting to establish a deep root system, which makes the tree more resilient later on.

Keep It Thriving

Care Guide

Do

Water regularly during dry spells, especially when young.
Mulch annually to protect the shallow root system.
Prune minimally to maintain its natural, graceful form.
Enjoy the four seasons of interest this tree provides.

Don't

Do not plant in heavy, waterlogged soil.
Avoid planting in high pH (alkaline) soils.
Don't over-fertilize; a yearly compost top-dressing is usually sufficient.
Avoid overhead watering, which can encourage fungal diseases.
