A colorful and shiny banner! Ornamental pears have such pretty fall foliage and also pretty white blooms in spring (though they don't smell nice), but the big drawback is their invasiveness---at least cultivars of Callery pear. There is another species of pear, Ussurian (Manchurian) pear, that might not be invasive, but I don't know much about it or how to tell the difference between the two.
