Acacia iteaphylla

Flinders Range Wattle

Botanical Name: Acacia iteaphylla
Family: Fabaceae
Origin: Flinders Ranges & eastern South Australia
Plant Type: Evergreen shrub to small tree

Overview

Acacia iteaphylla is a striking, fast-growing wattle with elegant, arching branches and long, narrow, grey-green phyllodes. From late autumn into winter it produces masses of golden-yellow, globular flower clusters that brighten gardens when little else is in bloom. Hardy and adaptable, it is excellent for screening, windbreaks, or as a feature plant in SA’s Mediterranean and semi-arid landscapes.

Key Features

• Mature Size: 3–5 m H x 3–4 m W (can be pruned to shape or kept smaller)
• Growth Rate: 20-50 cm per year under good conditions
• Foliage: Narrow, elongated phyllodes; grey-green to silvery tone; arching habit
• Flowers: Golden-yellow “pom-poms” in late autumn–winter; lightly fragrant
• Seasonal Interest: Strong winter flowering; year-round silvery foliage
• Wildlife Value: Attracts pollinating insects; provides shelter for small birds
• Tolerance: Very drought-hardy once established; frost hardy to –6 °C; excellent for arid and coastal gardens (including exposed second-line coastal); tolerates poor, shallow, rocky soils.
• Planting Density: Screening: 1.5–2m apart; Mixed border/mass: 1–1.5m; Specimen: 3–4m from next large shrub/tree
• Pet Friendly: Non-toxic / pet-friendly (as with any plant, ingestion of large amounts may cause mild tummy upset).

Where It Works Best

• Sunlight: Full sun (best) to light shade
• Soil: Adaptable to a wide range; sandy, loamy, rocky, and shallow soils; prefers well-drained
• Water Needs: Establishment: 2 deep soaks/week for 8–12 weeks. Established: deep soak every 3–4 weeks in summer (weekly in heatwaves); seldom in winter—only if dry
• Maintenance: Prune lightly after flowering to maintain shape and density; mulch in spring; tolerates harder pruning if rejuvenation needed
• Lifespan: 10–20 years (occasionally longer in ideal conditions)
• Climate Zones: Suited to temperate & Mediterranean SA; second-line coastal OK
• Soil pH:  Neutral to slightly alkaline

Landscape & Design Ideas

• Dense, fast-growing privacy hedge or screen
• Winter colour feature in native beds
• Attractive silvery foliage contrast plant
• Excellent for habitat gardens supporting birds and insects
• Tough windbreak for rural, coastal, or exposed sites
