Green Ash
Northern Red Oak

Green ash is a fast growing tree with incredible golden yellow leaves in fall. This tree is native to the prairies and is well suited for drought and cold. Green ash can also tolerate soil compaction, periods of flooding and a wide variety of soils including alkaline. This makes green ash ideally suited for use in urban environments.

Northern Red Oak is a medium-sized deciduous tree. It is fast-growing (for an oak tree) and is used primarily in lawns, parks, golf courses, street-side plantings, and commercial areas. Northern Red Oak's fall color is spectacular.

In open spaces, it has a short, massive trunk and an extensive crown. In forests Northern Red Oak grows with a tall columnar bole and small rounded head.

We are one of the only nurseries growing this tree.
