Answer: Salix 'Tortuosa', the Corkscrew Willow will grow to about 30 feet high with a 20 foot spread. Willows will take any kind of soil, even poor drainage, and still thrive. Willows like full sunshine and lots of water. The roots can be invasive, so keep the tree away from septics, drain fields, and underground wells. Nothing beats the wintertime silhouette of a Corkscrew Willow tree. Just give it lots of room to grow!
