Blueberry Ash

The Story

Plant Bio

Elaeocarpus reticulatus, the blueberry ash, is an upright evergreen tree or large shrub native to eastern Australia, characterized by glossy, tooth-edged leaves with prominent net-like venation. In summer, it produces hanging clusters of fringed, bell-shaped white or pale pink flowers, followed by blue, olive-like fruits.

The foliage emerges with bronze or light green tones before maturing to a deep, lustrous green, providing multi-colored interest throughout the growing season. The distinctive fringed petals give the blooms a delicate, shredded appearance that contrasts with the dense, conical canopy.

Uses & Benefits:

Features glossy evergreen foliage, delicate fringed summer flowers, and bright blue ornamental berries.

Serves as an effective, dense windbreak or privacy screen in mild coastal and maritime climates.

Provides nectar for generalist insect pollinators and shelter for local birds.

Planting

How to Grow

Select a planting site in full sun to partial shade with moist, well-draining soil.
Dig a hole twice the width of the root ball and set the plant at its original container depth.
Water deeply and regularly during the first few seasons to establish a deep root system.
Apply a light layer of organic mulch around the base, keeping it clear of the trunk to prevent rot.

Pro Tip

Never shear or prune hard into old, leafless wood, as the plant lacks the capacity to regenerate from bare branches and will leave permanent gaps.

Keep It Thriving

Care Guide

Do

Water regularly during dry spells to prevent drought stress and defoliation.
Prune lightly immediately after flowering to maintain shape and density.
Plant in a sheltered location to protect young growth from severe hard freezes.

Don't

Do not plant in heavy, poorly drained clay where water pools, as this triggers fatal root rot.
Do not prune hard into old, bare wood.
Do not allow the soil to dry out completely for extended periods.
