Queensland Silver Wattle (Acacia Podalyriifolia)

Queensland Silver Wattle — Acacia Podalyriifolia

The Queensland Silver Wattle is one of the most visually striking acacias you can grow, prized for its intensely silver-grey rounded leaves and spectacular clusters of bright golden-yellow pompom flowers that burst into bloom in late winter to early spring — when most gardens are still bare. Also known as the Pearl Acacia or Mount Morgan Wattle, it is a fast-growing evergreen shrub or small tree that brings year-round ornamental value to any sunny, sheltered garden.

Key Features

• Stunning silver-grey rounded foliage with year-round interest
• Masses of fragrant golden-yellow pompom flowers, January–March
• Fast-growing evergreen — quickly establishes as a specimen or screen
• Excellent as a container plant for patios and terraces
• Attracts bees and pollinators during late winter when little else is in flower

Planting & Care Tips

Plant in late spring in a warm, sheltered, sunny position with excellent drainage. In colder regions, grow in a large container using loam-based compost mixed with 20–30% horticultural grit, and move under cover before the first frosts. Prune lightly after flowering (March–April) to maintain a compact shape — avoid cutting into old hard wood. Feed with a balanced slow-release fertiliser in early spring.

Winter Care

In most of the UK, container plants should be moved into a frost-free greenhouse or conservatory before October. Garden-planted specimens benefit from horticultural fleece during cold spells and a thick mulch over the root zone. Young plants are more vulnerable than established ones and should always be protected.
