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.
Weeping willow trees are deciduous -- trees that lose their leaves in the fall. The tree is a native of western China and grew in ancient Babylon, which is where its Latin name, salix babylonica, comes from. The weeping willow tree is a fast grower, growing 8 to 10 feet in a year. Unfortunately, fast-growing trees do not have a long lifespan -- the weeping willow's is 50 to 100 years. Weeping willow trees grow to about 50 feet tall, with an equal spread.
