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.
The white willow is a fast-growing, low-branching tree with a crown height reaching up to 80 feet and a crown spread up to 70 feet. The bark of this tree is furrowed and grayish or yellowish brown in color; the yellow to brown twigs have a tendency to droop slightly, but not as much as a weeping willow. The leaves are serrated and medium green on top with the whitish downy undersides, which turn a bronze yellow in autumn.
