Manitoba Butternut (Juglans cinerea)

Butternut trees grown from locally collected Manitoba seed. The butternut, also known as white walnut, is a hardy tree that grows slowly and is native to eastern North America. It can reach 12 to 18 metres tall with an open, spreading crown.

This deciduous tree has compound leaves with serrated leaflets, light grey bark, and distinctive oval nuts with deeply ridged shells. Butternuts are sweet and oily, enclosed in sticky green husks that ripen and fall from September to October. The species naturally grows in soil with good drainage along rivers and in mixed hardwood forests, and favours full sun.
