Hazelnut, Wepster


Corylus avellana

Wepster is very productive and produces very high quality flavorful hazelnuts. One of the 3 latest varieties from Oregon State University’s disease resistant hazelnut breeding program. These three 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. Wepster is a vigorous tree and has good blight-resistance, 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 McDonald to produce a crop.

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

Ripening time: August-September

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




Wepster is a very productive flavorful nut, developed for the chocolate, nut industry that ripens early in the season. The vigorous, open shaped, completely blight resistant tree, is easily maintained at 10' tall, requires little training and is a reliable producer. It blooms mid season and McDonald and York are excellent pollinizers. It is newly developed by OSU and named for nut tree pioneering Wepster family.
