River Birch or Betula Nigra:
River birch's "Heritage" cultivar was selected 2002 Tree of the Year by the Society of Municipal Arborists. The tree's wood has very little commercial value but river birch is extremely popular as an ornamental. It is hardy for all U.S. climate zones, is fast-growing, nicely forked, and wind and ice resistant. River birch peels in colorful flakes of brown, salmon, peach, orange, and lavender and is a bonus for regions deprived of paper and white birches.
Habit and Range:
River birch is well named as it loves riparian (wet) zones, adapts well to wet sites and reaches its maximum size in rich alluvial soils of the lower Mississippi Valley. However, the tree is very heat-tolerant and can survive modest droughts. River birch transplants easily at any age and grows into a medium tree of about 40' to 70'. River birch occupies a large eastern north-south ranges in North America - from Minnesota to Florida. The tree is very intolerant to shade.
