The Story
Plant Bio
Acacia cognata, commonly known as river wattle, is an evergreen Australian shrub or small tree native to the dry sclerophyll forests of New South Wales and Victoria. The species naturally occurs on sandstone- and granite-derived soils, producing narrow, weeping foliage and pale yellow globose flower heads in the leaf axils.
'Fettuccini' is a compact, mound-forming cultivar selected for its highly textured, rippled foliage that resembles pasta. The new growth flushes with coppery-bronze tones before maturing to a bright lime-green, providing year-round structural interest.

Planting
How to Grow
- Select a planting site with full sun to partial shade and highly permeable, well-draining sandy loam or loam soil.
- Dig a hole twice the width of the root ball and of equal depth, ensuring the plant sits at the same level as it did in the pot.
- Backfill the hole, firm the soil gently, and apply a deep soak to settle the roots.
- Water regularly for the first eight to twelve weeks to establish the root system, then reduce watering to dry periods only.
Pro Tip
Never prune back into old, leafless brown wood; this cultivar lacks dormant buds on mature stems and will fail to reshoot, causing permanent branch dieback.
