This delightful grassland plant forms a low mounding shrublet of up to 30 -40 cm high. Flowers are typical of this family, a pale buttery yellow in colour with a white or cream corolla covering the plant from October to March. It forms a tube of up to 2.5 cm which widens at the base, and the lobes (petals) are up to 5 cm across. Leaves are softly hairy, mid-green and oval in shape, up to 5 cm long and 2 cm wide. This grassland biome species flowers profusely after a fire. While this little groundcover does best in full sun and well-draining soils, I find it also thrives in slightly damp soils and light shade from mid-afternoon onwards. In wild grasslands, it is often lightly shaded by neighbouring species and grasses, and through the season will grow upwards and send out limbs in search of a sunny spot. Pop in the front of a mixed grassland bed or as an edging plant along a pathway.
