Betula nigra 'Cully' Heritage
Object Details
- Description
- This drought and flood tolerant birch cultivar has exfoliating bark that can be almost as white as some white birches. While it is able to withstand heat and pests slightly better than the species, it is not quite as tolerant as the Dura Heat river birch. The cultivar name ‘Cully’ gives credit to Earl Cully, who found this birch growing in St. Louis, Missouri.
