The long, wispy branches of willow trees give them an appearance unlike any other tree. They require a lot of water so look for them along wet areas. Their high demand for water can cause problems when used in landscaping as their roots will invade and clog sewer and water pipes.

The inner bark (cambium layer) can be shredded and chopped then boiled into a porridge to obtain calories. The outer bark of young branches is shredded then made into a tea which contains the precursor of aspirin and will give all the medical benefits (and dangers) of aspirin. The best results are achieved using pencil-thick branches harvested in late winter before the leaves begin to bud.

Willow branches are high in a chemical called Gibberellic acid which is a plant hormone responsible for triggering root growth. The rooting powder and solution purchased in stores to help propagate plant cuttings is this chemical. You can make your own rooting solution by grinding up willow twigs in a clean pencil sharpener then soaking these willow shavings in water for 5-7 weeks. When you want to propagate a plant via a cutting dip the cutting's stem in this willow solution first.

Dried, shredded willow bark is often added to herbal smoking mixtures to give a heavier flavor more like that of true tobacco.
