Butternut (White Walnut)

White Ash is a large deciduous tree that's often grown in residential yards and along boulevards.

Similar to Green Ash, White Ash is distinguished by the lighter colour of the undersides of the leaves.

While Green Ash turns gold in the fall, White Ash turns a gorgeous burgundy.

Butternut is one of the few walnut varieties native to Canada. The nuts are sought after for their mild, sweet, and oily taste. Ensure this tree is planted in full sun and well-drained soil for best results.

Butternut is self-fertile but it has better yields when planted near other butternuts. It can survive in zone 2, but reliably produces nuts in zone 3.

A top CO2 absorbing species. Experts think this tree may help climate change more than others.
