About Humboldt's willow
Salix humboldtiana, commonly known as Humboldt's willow or Chilean willow, is a fast-growing deciduous tree native to South America. It is characterized by its broad, irregular canopy and flexible, drooping branches, which give it an elegant, weeping appearance. It is ideal for planting near water bodies, where its silhouette is beautifully reflected, or in large parks and gardens that require a substantial focal point.
Native range
South America, from southern Colombia to central Argentina and Chile
Care tips
This willow prefers full sun exposure for optimal growth, although it tolerates partial shade. It requires abundant and consistent watering, especially during warm months, as it is a moisture-loving tree that thrives in well-drained but humid soils. The ideal substrate is rich in organic matter and has good water retention. A common mistake is not providing it with enough water, which can stress the tree and affect its development.
