Hazelnut, McDonald


Corylus avellana

McDonald is one of the 3 latest releases from Oregon State University’s disease resistant hazelnut breeding program. The latest releases – McDonald, Wepster and Polly O – all have cross-compatible pollen, significantly reducing the complication of growing hazelnuts (filberts) both at a commercial and home scale. McDonald is a heavy producer of delicious nuts. It is a very blight-resistant variety, a critical feature in the Pacific Northwest where Eastern Filbert Blight devastates trees without disease resistance. Can be grown as a large bush or tree depending on pruning.

USDA Zone: 5-8

Pollination: Plant with both Polly O and Wepster to produce a crop.

Time to productivity: 2-3 years depending on conditions.

Ripening time: September

Size: Can grow to 12′ or be kept smaller as a bush.




McDonald is a heavy producer of delicious kernals with a very high nut meat-to-shell ratio. This new, highly blight-resistant selection from Oregon State U. blooms for longer than any other variety and ripens early in the season. McDonald is an upright, open-form filbert bush/tree that can be maintained at 10' tall. Wepster, as well as York, Polly-O, and Yamhill, are excellent pollinizers for this popular variety.
