Whortle-leaved willow is a demanding species as regards nutrient availability. It is a small shrub native to the northern parts of Eurasia. The flowering takes place at the emergence of the leaves. The branches of this species are thick and reddish-brown. Hybrids between willow species are common. Whortle-leaved willow crossbreeds quite commonly with gray willow (S. glauca) and dark-leaved willow (S. myrsinifolia).
