Bark greyish-brown, deeply fissured. Twigs very slender, at first thinly subadpressed pubescent, soon becoming glabrous. Golden- or greenish-yellow in their first year, later becoming olive-green. Catkins appearing with the leaves in April, terminal on very short, spreading, leafy, lateral shoots, peduncle and rhachis softly villose. Catkins male, female or most commonly androgynous.

Salix fragilis also spreads by root suckers, expanding into pure 'groves'. "Salix fragilis" is cultivated as a fast-growing ornamental tree. The cultivar "Salix fragilis" 'Russelliana' (syn. "S. fragilis" var. "russelliana" (Sm.) Koch) is by far the most common clone of crack willow in Great Britain and Ireland, very easily propagated by cuttings. It is a vigorous tree commonly reaching tall, with leaves up to 15 cm long. It is a female clone. "S. fragilis" has escaped cultivation to become an invasive species in various parts of the world, including: New Zealand; the upper half of the United States; and South Africa. In
