Ingleside Quality... Betula nigra 'Dura Heat'

Betula nigra 'Dura Heat' 
10-12' #25 PNP

Consistent Quality... that's what you need today and that's our goal and constant effort here at Ingleside.  It is difficult.  We're growing a natural product with many variables.  But, here's an example of what we strive for everyday.  Our latest crop of Dura Heat is very consistent.  Great cane size and overall structure.  Quality you can count on!  Currently, IPN has Dura Heat in the following sizes:  8-10' #15, 10-12' #25, and 12-14' #65.

Missouri Botanical Garden (MOBOT.ORG) says:
Dura Heat River Birch is a vigorous, fast-growing, medium-sized tree that is native from Minnesota to New Hampshire south to Florida and Texas. Typically found growing along streams and gravel beds, DURA-HEAT is a somewhat smaller cultivar that features better creamy white bark color, better tolerance to summer heat, better insect and disease resistance and superior foliage to the species. It typically grows 30-40’ tall as a single trunk or multi-trunked tree. Multi-trunked trees form a more irregularly shaped crown and are usually considered to be the superior growth habit for this tree. Exfoliating salmon to cinnamon bark reveals creamy white inner bark that can be nearly as white as the white-barked birches. Leathery, diamond-shaped, dark green leaves (to 3” long) with doubly toothed margins and tapered tips turn an undistinguished yellow in fall.
