This section of the garden is dedicated to a very peculiar tree of the Canary Islands flora, the Canary willow, whose scientific name is Salix canariensis C. Sm. ex Link. This tree cannot be associated with any specific vegetation zone in the Canary Islands, although it is usually found mainly associated with the thermophilic sclerophyllous forest, as it has a wide ecological range, being able to inhabit watercourses from the coast to the summit, except in the area where the hygrophilous laurel forest predominates, characterized by the til, whose scientific name is Ocotea foetens (Aiton) Baill., this is because the limiting factors for its development are the presence of light and a constant flow of water, either on the surface or underground.

For all these reasons, the Canary willow is considered a bioindicator species of the presence of water, since wherever it is found there must be a constant watercourse, as occurs in the Barranco de Afur, where it grows up to sea level, or in the streams on the border of the Teide National Park, where its presence is associated with a natural source of water.

Due to this dependence on water, this plot has an irrigation system installed that helps the development of the trees and the sustenance of the willows, ensuring that they do not suffer from a lack of water in the summer.
