Lechenaultia biloba is a low, spreading to mounding shrub that typically grows to around 30–50 cm high and can spread to 1 m wide. It has fine, soft green foliage with narrow leaves arranged along slender stems, creating a delicate, textured appearance. Masses of spectacular fan-shaped flowers appear from late winter through spring, most commonly in vivid blue, though forms with mauve or pink-toned flowers also occur. Its brilliant floral display makes it ideal for rockeries, raised garden beds, containers and cascading over retaining walls.
Lechenaultia biloba is native to the south-west of Western Australia, where it grows in heath and open woodland on sandy, gravelly and lateritic soils with excellent drainage. It performs best in a sunny position with free-draining, low-phosphorus soils and dislikes prolonged wet conditions, particularly in humid climates. To minimise grey mould, avoid overhead watering and keep the foliage as dry as possible. Light pruning after flowering can help maintain a compact habit and encourage fresh growth.
