Okie chestnut tree (Grafted) - This European chestnut tree produces a very large nut, one of the biggest any chestnut tree produces. It is also one of the best pollinators for the Colossal chestnut trees, as well as any other chestnut tree with a early to mid season bloom. The tree is a little more spreading than the Colossal chestnut tree but left to grow it can reach heights of over 50 feet. Nuts have more splits than other pollinators such as Marival and Prococe Migoule.
Okie is not as cold hardy as Colossal and may experience winter kill in some of the colder parts of the USA. In Northwest Washington state, Okie has never had any cold damage.
