🔥 Stenocarpus sinuatus
Firewheel Tree with Brilliant Wheel‑Shaped Blooms

Stenocarpus sinuatus, commonly known as the Firewheel Tree, is one of Australia’s most spectacular ornamental trees, celebrated for its brilliant wheel‑shaped flower clusters. Each bloom forms a circular “firewheel” of bright red to orange tubular flowers, creating a dramatic display against its glossy, deep‑green foliage. Even when not in bloom, its elegant leaves and upright form make it a refined landscape specimen.

Well suited to subtropical, Mediterranean, and water‑wise landscapes, Stenocarpus sinuatus thrives in full sun to light shade with well‑drained soil. Its slow, steady growth and long lifespan make it ideal for feature planting, courtyard gardens, and architectural landscapes where its unique flowers can be showcased.
