If the company won't provide them for free, invest the $10 to order one of its books from Amazon. You want to see how the books look and feel. Most authors I work with do not ask for samples, and this is putting a lot of faith into the hands of a company that's producing something so important to you.
Another good thing about corkscrew willow is its fast growth. Like most willows, it grows 24 inches or more in one year, reaching a mature height of 25 to 30 feet with a spread of 15 to 20 feet. Now for the bad news: like other willows, corkscrew willow is short-lived. Most fast-growing trees have brittle branches and are prone to breakage. Corkscrew willow is no exception.
Dappled Willow shrubs have a spreading starburst shape while young, but develop a drooping fountain shape as they mature. They usually grow 4 to 6 feet tall and wide, but can grow up to 10 feet tall. The mottled green and white foliage of Dappled Willows turns salmon pink in late spring or early summer. The leaves turn golden yellow and remain on the shrubs until late fall. Yellow catkins appear in the spring before the leaves bud out.
