Maclura pomifera
Osage Orange
"
A native to the mid-United States, M. pomifera is occasionally found in hedgerows in Ontario. Known for its distinctive large green fruit the size of oranges, it is also a relative to the Mulberry. The grey, lightly fissured bark is quite attractive. The yellow autumn colour is quite intense and makes a definite contribution to the landscape. Pollution tolerant it may see some use as an urban tree if male trees are planted.
