Overview
Weeping willow (Salix babylonica) is instantly recognizable for its sweeping, pendulous branches and slender, drooping foliage. A fast-growing deciduous tree, it forms a broad, rounded canopy that can be as wide as it is tall.
Deeply associated with water, it is most at home along ponds, lakes, and streambanks. Its vigorous, water-seeking roots make it beautiful but problematic near pipes, drains, and foundations. The bark contains salicin, the natural compound related to aspirin.
How to identify it
- Branches: Long, slender, golden-brown branches that hang straight down, often touching the ground
- Leaves: Narrow, lance-shaped, finely toothed leaves, light green above and pale beneath, turning yellow in fall
- Form: Broad, rounded, weeping crown 30-50 ft tall and often equally wide
- Bark: Gray-brown, rough and deeply ridged on mature trunks
- Catkins: Slim yellow-green catkins in spring
Care & growing
Light: Full sun.
Water: Loves abundant moisture; ideal near water and tolerant of wet, poorly drained soil.
Soil: Adaptable, but thrives in damp, fertile ground.
Temperature: Hardy USDA zones 4-10 (depending on type).
Feeding: Rarely needed given its fast growth.
Propagation: Extremely easy from hardwood cuttings, which root readily even in water. Keep away from buildings, septic systems, and pipes due to aggressive roots.
Habitat & origin
Weeping willow originates from northern China and has been cultivated and spread along trade routes for centuries (the species name references Babylon). It naturalizes along watercourses in temperate regions.
It is widely planted worldwide as an ornamental beside ponds, lakes, rivers, and in large damp lawns.
Uses & benefits
- Ornamental: A classic landscape specimen for waterside settings, prized for its graceful, weeping silhouette
- Practical: Roots help stabilize streambanks and control erosion; flexible stems used in basketry
- Medicinal (traditional): Bark contains salicin, historically used for pain and fever and chemically related to aspirin
- Ecological: Provides early-season pollen for bees and habitat near water
Frequently asked questions
Where should I plant a weeping willow?
In a large open space near water and well away from houses, pipes, and septic systems, since its aggressive roots seek moisture and can damage them.
How fast does a weeping willow grow?
Very fast, often several feet per year, but it is relatively short-lived compared with oaks, typically lasting a few decades.
Is weeping willow related to aspirin?
Yes. Willow bark contains salicin, a compound chemically related to the active ingredient in aspirin, and was used for pain and fever long before aspirin was synthesized.
Can I grow a willow from a cutting?
Easily. Willow stems root readily, even just placed in water, which is one reason willows spread so quickly along waterways.
