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.

Royal Frost Birch is a beautiful, cold hardy tree. It features burgundy-red-purple foliage, turning a showy yellow-orange-red in fall. The attractive white bark is striking on a winter landscape.

Royal Frost Birch loves moisture. To meet this trees' moisture needs, try applying bark mulch over the root system. Keep in mind that this variety only likes to be pruned in summer to avoid “bleeding” sap.

The Royal Frost cultivar is popular for its upright pyramidal growth habit and fuller purple foliage.
