Betula nigra 'BNMTF'

Spread: 25-30'+
Shape: Pyramidal
Foliage: Deciduous; green.
Fall Color: Yellow.

Comments: Dura-Heat® offers superlative lustrous dark green leaves that turn soft butter yellow in the autumn.
The leaves are more leathery and smaller than other varieties and the species. Leaves are closely
spaced along the length of the shoots resulting in a dense canopy of foliage, even on young trees. Leaf
spot resistance is significantly greater than that of other varieties and the species. Side-by-side comparisons
of Dura-Heat® foliage against other varieties or the species leave no room for doubt about the
superior foliage characteristics.
