Another western WA nursery that has N Gift is Raintree nursery. I've ordered Nikitas Gift trees from both Burnt Ridge and Raintree. The trees from Raintree were larger than those from Burnt Ridge both in terms of height and caliper, likely accounting for the price difference.
Edible Landscaping Nursery is great. They have a lot of american and Asian varieties. Their plants are in pots instead of bare root. I was disappointed in the taste and texture of Nikita’s Gift. Sweet and mushy.
