The 'Dura Heat' River Birch is a highly resilient, fast-growing shade tree specifically engineered to thrive where other birches struggle. While classic white-barked birches look beautiful, they notoriously fail in hot, humid southern summers and are highly susceptible to the bronze birch borer. 'Dura Heat' addresses both issues: it boasts superior heat tolerance, holds its leaves much later into autumn without dropping them early from summer stress, and is highly resistant to pests.
