White Willow (Salix alba 'Tristis')

Reaching about 75 feet tall, this white willow cultivar is sometimes called the golden weeping willow because each year's new twigs are yellow. Willow tree bark contains a plant hormone called salicylic acid (named after Salix, the tree's genus name), which is closely related to aspirin. And the next time you visit a pharmacy, note how many products contain salicylic acid—everything from shampoos to skin treatments.
