Butternut (White Walnut) vs Burton Hican
Juglans cinerea
Carya ovata x illinoinensis Burton
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.
Burton Hican is a rare cross between Shagbark Hickory and Pecan. Most Hickory x Pecan hybrids are not reliable producers but the Burton Hican produces large crops annually (in warmer climates). The medium sized nuts fall in between the Pecan and Hickory and are known for having a great flavor. They are well suited to fresh eating, cooking, and baking with a good storage life.
Hicans will carry features from both species. The Hickory influence causes earlier ripening times while the taste and productivity come from the Pecan. The Pecan genetics also cause the nuts to have a thinner shell that is easier to crack and the pecan-like shape makes kernel removal easier.
The Burton Hican is generally considered self pollinating but having a second variety for cross pollination will increase nut production. They have been known to cross pollinate with other Hicans, Shagbark Hickory, and some Pecans. Nut production is expected after 7-10 years.
Note: Plant this tree once. Due to its large tap root transplanting is not recommended.
