Xerothamnella parvifolia is a low, spreading, drought-hardy shrub of arid inland Australia, growing to about 1 m with small thick leaves and white, red-marked tubular flowers. It is a wild species of rocky hillsides and stony rises rather than a common garden plant, so it suits dry, open, well-drained sites.

About
Xerothamnella parvifolia, commonly known as the small-leaved little dry shrub and regionally in South Australia as the freckled duck, is a flowering shrub in the family of Acanthaceae. The species occurs in south-west Queensland, far north-west New South Wales and the Flinders Ranges of South Australia, where it inhabits rocky hillsides, stony rises and chenopod shrublands in arid and semi-arid environments.
Where it grows
Flowering period can be hard to predict and often opportunistic corresponding with rainfall, records show that flowering period can extend from October through to April. Following flowering, plants produce smooth fruit capsules approximately 7–8.5 mm long. Capsules contains 1-2 seeds 4 mm long and 3 mm wide that are brown and display a textured outer layer known as Tubercle. Published information on the reproductive ecology of X. parvifolia is limited, however available evidence suggests that the species has lower reproductive output than X. herbacea.
