About
Clematis aristata, known as Australian clematis, wild clematis, goat's beard or old man's beard, is a climbing shrub of the family Ranunculaceae, found in eastern Australia in dry and wet forests of Queensland, New South Wales, Victoria and Tasmania. In spring to early summer it produces mass displays of attractive star-shaped flowers usually borne in short panicles with each flower up to 70 mm diameter and possessing four narrow white or cream tepals. Fertile male and female reproductive structures occur in flowers of separate plants (dioecy) making this species an obligate outcrosser with pollen movement among plants most likely facilitated by insects. Each seed head (or infructescence) on female plants consists of multiple achenes (an aeterio) with each seed bearing a plumose awn 2–4.5 cm long promoting dispersal by wind.
How to grow it
Clematis aristata is a popular hardy garden plant. It prefers a semi-shaded or shaded position and cool deep soils and will withstand heavy pruning. It is a vigorous climber and may become a problem by smothering other plants.
Propagation can be carried out from fresh seed and from cuttings of semi-hardened stems.
