Salix apoda
Salix apoda, the Caucasian willow (an appellation it shares with other members of its genus), is a species of flowering plant in the family Salicaceae, native to the Caucasus and northern Turkey. A prostrate shrub, it is occasionally cultivated as an ornamental ground cover in rock gardens, particularly the males, since they produce large, silvery catkins that then erupt in yellow stamens.
