Appearance

''Salix lanata'' is a low, many-branched, deciduous shrub, generally less than 100 cm high by 150 cm broad. The new twigs are hairy at first, soon becoming hairless and brown. The grey-green leaves are rather variable, but generally ovate up to 7 cm long by up to 6.5 cm wide, covered in silvery-grey "wool" to begin with but less so with age. The leaf margins are usually entire.

The catkins appear in summer , with male and female catkins on separate plants . The female catkins are densely hairy. The petioles are usually less than 1 cm long, and the stipules usually 1 cm long by 0.6 cm wide, and persistent.

The texture, colour and compact nature of this plant, together with its extreme hardiness, make it a valuable plant for cultivation. It has gained the Royal Horticultural Society's Award of Garden Merit.
