Iseli Fastigiate Blue Spruce is perfect if you are looking for colour all year. A cultivar of the Blue Spruce, it is also known as the Columnar Colorado Blue Spruce. The Iseli Fastigiate Blue Spruce is one of the more distinctive evergreens. Its foliage is blueish in the spring and blue/green in the winter. Best used as an accent tree, the Blue Spruce has a narrowly upright and columnar form with upwards forking branches.

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.
