About
Salix _ fragilis, the crack willow, is a variable hybrid tree of fast growth with channelled bark and characteristically brittle shoots. Slender, green catkins are produced in early spring. Lance-shaped, finely toothed, sometimes glossy leaves complete the display. A rewarding willow for large, moist garden sites or riparian planting.
About the genus
Salix, the willows, are deciduous shrubs and trees of very diverse habit, with simple leaves and tiny flowers in catkins, male and female usually on separate plants. Some are valued for brightly coloured winter shoots, others for ornamental catkins, foliage or stature.
