Banksia Petiolaris, commonly known as Prostrate Banksia, is a unique Australian native groundcover shrub valued for its bold flowers, spreading habit, and excellent landscape performance. Its low-growing form makes it ideal for rockeries, embankments, native gardens, coastal-style landscapes, and large garden areas where a tough, decorative groundcover is needed. Once established, it offers strong visual impact while helping to cover open spaces and assist with erosion control on slopes.
This attractive Banksia features leathery, serrated green foliage with a spreading habit and upright cylindrical flower spikes in yellow, green, and brown tones. The flowers rise above the foliage, creating a striking display that adds colour, texture, and wildlife value to the garden. Banksia Petiolaris is a rewarding choice for customers wanting a hardy, low-maintenance native plant with strong ornamental appeal and practical groundcover use.
