Japanese Tree Lilac

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.

Japanese Tree Lilac is an attractive, heavy-flowering lilac with fragrant white blossoms. It can be pruned to a single stem or grown as a multi-stemmed shrub.

Japanese Tree Lilac's dark reddish-brown bark peels as the tree ages, creating visual appeal for any yard, especially in the winter.

This tree is often planted along boulevards and its attractive white flowers signal spring to all who drive by.
