Willow: Botanical Profile of a Plant

Willow branches are harvested between October and January. The bark is peeled off the cut branches and then gently dried. Extracts from the bark is used as ingredients in natural cosmetics.

Plant

The willow is a group of deciduous broadleaf trees, shrubs and dwarf shrubs. Thanks to their tough, strongly branched roots that reach into the groundwater, willows are able to thrive in dry environments. Their extensive root system is well aerated, and holds the soil together to help prevent against erosion. Willows are therefore used as protective plantings along shores, embankments and slopes. There are about 400 willow species, most of them found in Europe, northern Africa and the Middle East. The genus name, Salix, is said to derive from the Latin salire (to jump), in reference to the willow’s rapid growth.

Blossoms

The willow is dioecious, which means that female and male flowers are on separate plants. The flowers appear as slender flower clusters or spikes, called “catkins”, which usually emerge in spring even before the leaves. Willow catkins differ both in size and colour. Female catkins are smaller and green in colour, while the larger male catkins are covered in yellow stamens that make them look furry. The flowering period is from April to May, around the same time that the willow comes into leaf. Its seeds ripen from June to July, and are covered in long, white hairs that help them to spread by wind.

Use

Willow branches are harvested between October and January. The bark is peeled off the cut branches and then gently dried. Extracts from the bark is used as ingredients in natural cosmetics. Willow bark extracts have antimicrobial and skin-soothing properties.
