Description

Usually 3 to 6 metres in height, sometimes reaching 12 metres tall and a 45 cm trunk diameter. The long leaves and their ''woolly'' white underside makes it easy to identify. Blanket Leaf is often crooked and asymmetrical. The trunk is not straight, irregular in cross section but not buttressed. The main branches form close to the ground. Small branches covered in a whitish felt. Older branches covered in stringy and flaky brown bark. Leaves alternate, entire, wavy edged. White underneath, dull green above. 15 to 24 cm long and 2 to 4 cm wide. The midrib is sunken on the top side, but raised on the lower side. Yellow flowers without ray florets form on

, whitish with bristles on the top. 8 mm long in the shape of a cigar. Fruiting occurs from December to January. Whilst in no way related, the first impression of a healthy stand of blanket tree is strongly reminiscent of the rhododendrons of the Himalayas and China. This is due to similar growth habit, leaf arrangement and shape and is consistent with a plant which grows in the middle vegetation layers, and which has the role of shading the ground. Following the bushfires in the summer of 2006 in the Howqua Valley, Victoria, Australia, a substantial area of forest has been colonised by Bedfordia arborescens as an understory in the eucalypt dominated valleys south of Mount Timbertop.
