The '''Common Osier''' (''Salix viminalis'') also known simply as '''Osier''', is a many-branched [[shrub]]by species of [[willow]] (''Salix''). They usually grow to between 3-6 m in height. It has long, straight branches with exceptionally long, slender leaves, around 10-15 cm in length but only 1 cm broad. The flexible twigs means that it is commonly used in [[basket]]ry, giving rise to its alternative common name of "basket willow". Another increasing use is in [[energy forestry]]

The leaves are dark green, with a silky grey underside; the male [[catkin]]s are yellow and oval-shaped, and appear in early [[Spring (season)|Spring]] before the leaves. In contrast, the female catkins are longer and more cylindrical, appearing around the same time as the leaves.

Osiers are commonly found by streams and other wet places. They are widespread throughout both [[United Kingdom|Britain]] and [[Ireland]], but only at lower [[altitude]]s. It is one of the least variable willows, but it will [[hybrid]]ise with others.
