Black Locust can grow in many situations, but prefers dry areas with lots of sun. It is robust and is an excellent choice for establishing shade in dry, open areas.

The York Hazelnut is a high yielding deciduous tree. It produces delicious medium to large sized nuts that are great for eating or making a paste. Known to be resistant to eastern filbert blight.

It has a long bloom season and is compatible with most cultivars, making it a great pollinizer. Try pairing York Hazelnut with Yamhill Hazelnut.
