Salix sepulcralis group inheritied from its parent the twisted and contorted branches, as well as being more cold-tolerant, as "S. babylonica" var." matsudana" is native to northern China and Korea. These trees are usually no more than tall. Leaves are finely serrulate, pubescent or silky when young. Ovaries are short and flask-shaped, not much longer than the subtending catkin scale. They are usually intermediate between the parent species, showing the typical weeping willow appearance with leaves that are pale glaucous below. But as an ornamental tree with high diversity, trees may look closer to either parent or different entirely. Salix sepulcralis group The
Salix myrtilloides new leaves appear. The leaves resemble bilberry ("Vaccinium uliginosum") leaves in shape, hence the name in the Finnish and Swedish languages, which translates as "bog bilberry willow".

Salix myrtilloides Salix myrtilloides, the swamp willow, is a willow native to boglands in cool temperate to subarctic regions of northeastern Europe and northern Asia from central Norway and Poland eastwards to the Pacific Ocean coasts, with isolated populations further south in
