The ‘Cully’ cultivar of the River Birch was discovered in a St. Louis, Missouri suburb and introduced by Earl Cully, a well known arborist from Illinois. The ‘Cully’ grows 40’ tall and 40’ wide.
As a relatively heat-resistance tree in the Birch family, the River Birch tree’s distribution extends further south than most other Birch trees. River Birches have papery, scaly bark, and often has multiple thin trunks rather than one large trunk. An ornamental tree, the ‘Cully’ cultivar is very similar to the ‘BNMTF’ cultivar in that it is a lighter colored tree that is resistant to the Bronze Birch Borer beetle species.
