Butternut (White Walnut)

Dahurian Birch is a rare and interesting ornamental with curling bark. This tree is the first to sprout on bare land and is tolerant of dry, gravelly, and infertile soils. Dahurian Birch can grow in industrial areas or exposed land as long as it has full sunlight.

This tree is ideal for landscaping, ornamental, and ecosystem services.

This tree is not well known, but is a favorite of nursery owners across the country.

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.
