Green Ash
White 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.

White Oak is large, long-lived tree with an irregular trunk divided into spreading, often horizontal, stout branches. A highly adaptable tree, White Oak features green acorns and beautiful green leaves that turn red-purple in the fall.

With a huge growth in bourbon and scotch over the past few decades there is an emerging shortage of white oak that is the primary tree used for cask barrels and aging.

Note: Most Oak species can be considered toxic for many animals.
