This plant was originally
introduced to assist with the
revegetation of degraded soils
in various parts of Australia,
however it has since spread and
naturalised across vast regions
of northern Australia. The plant
is an erect, multi-stemmed,
soft-wooded, perennial herb
to 1.6 m high. It has broad
leaves that are densely covered
in short, branched hairs, giving
it a grayish appearance. Flowers
and fruits for most of the year.
