Willow

Willows excel as living structures, erosion control, and water filtration systems in permaculture designs. Their flexible branches create living fences, arbors, and children's play structures. Fast-growing and coppiceable, they provide biomass, shade, and windbreaks. Plant near ponds, swales, or greywater systems where their roots help purify water while stabilizing banks and preventing erosion.

Willow bark contains salicin, the precursor to aspirin, making it valuable for pain relief, fever reduction, and anti-inflammatory treatments. Traditional uses include treating headaches, arthritis, and lower back pain. Harvest bark from 2-3 year old branches in spring. Make teas, tinctures, or topical preparations. Young leaves can be used similarly but are less potent than bark.

Young willow leaves are edible raw or cooked, with a bitter, aspirin-like taste. Inner bark can be dried and ground into flour for survival food. Catkins are edible but bitter. Young shoots can be peeled and eaten. Willow leaves make a medicinal tea. Generally considered famine food rather than culinary ingredient due to strong bitter flavors and medicinal compounds.

Willows support over 450 insect species, making them exceptional wildlife plants. Early spring catkins provide crucial nectar for bees and pollinators. Dense growth offers nesting sites for birds. Roots filter nutrients and pollutants from water. They colonize disturbed ground, beginning succession. Fallen leaves decompose quickly, enriching soil. Create habitat corridors along waterways and support diverse wetland ecosystems.

Identify willows by alternate, simple leaves typically lance-shaped with finely serrated edges. Catkins appear before or with leaves in spring. Bark varies from smooth to deeply furrowed. Multiple stems often grow from base. Young twigs are flexible, often colorful (yellow, orange, red). Leaves usually narrow, 3-15cm long, with pale undersides. Over 400 species exist with considerable variation in form.

Willow wood is lightweight, soft, and not durable for structural building. However, flexible young stems excel in traditional crafts: basketry, wattle fencing, and living structures. Larger timber used for cricket bats, boxes, and artificial limbs due to lightness and shock absorption. Poor for construction but valuable for bentwood projects, garden structures, and biomass production through coppicing.

Willow water, made by soaking cut stems, contains natural rooting hormones (auxins) that help propagate cuttings. Ancient Egyptians used willow for pain relief. The phrase 'wearing the willow' meant mourning lost love. Willows can grow from stakes pushed into ground upside down. Some species can photosynthesize through their bark. Napoleon was buried under willows, later grown from cuttings worldwide.
