Betula nigra Northern Tribute« 'Dickinson' (Northern Tribute« River Birch)
This is proving to be the most adaptable river birch to dry and alkaline soil conditions in addition to be completely hardy in zone 3. So, no die back from winter injury and no iron chlorosis or the mortality that can cause. The parent tree is the largest of this species observed in the upper Northern Plains; it has a proven track record of over 40 years. Ivory colored with striking coppery-bronze exfoliations the bark is appealing year round. Resistant to borers as well.
With attractive lacey foliage that is very sweetly scented this makes an attractive, colonizing, small shrub that should be planted where it can be seen closely and easily touched to release its fragrance into the air. It has a long history of medicinal uses but is seen less frequently than deserved outside the North East.
Quercus macrocarpa (North Dakota source) (Bur Oak (North Dakota))
Native across a broad range in the eastern US, it is consequently variable in leaf form, size and growth rate. Our seedlings are of Missouri source. This patriarch forest tree is best for parks and large, open landscapes.
