Hardy TropicalsHardy Orange
A spiny deciduous species from China and Korea, this relative of the Florida orange grows in Niagara and bears fruit in the fall. While these look like oranges and are in fact edible, they are not very tasty.  In May or June, white flowers about 1-2 inches wide erupt, and its trifoliate leaves come on, growing into a rich glossy backdrop for the dull, fuzzy, little green fruits that form. Bark is striped and in fall its dark green leaves turn butter yellow before dropping. Its small orange fruit is very fragrant, often picked and dried for potpourri.
