Reuse an old tree to make a log pathway in your garden. Good use of "yard" trees and other wood that can't be milled; works much better in climates without termites. Good drainage under the log rounds will make the path last longer.
I would love to walk under this gorgeous canopy and allow the dense foliage provide cool shade during the warmer months, then as the weather cools and the leaves fall, the winter sun is allowed to penetrate. The flowers are highly scented.
