AU Super

‘AU Super’ (C. mollissima) is from Auburn University, but it was never formally released as a cultivar. It was dubbed ‘AU Super’ by Hongwen Huang during his time at Auburn. It has relatively large nuts that ripen late during the season. Nut and tree morphology indicate that it is not related to the other Auburn releases (‘AU Cropper’, ‘AU Leader’, and ‘AU Homestead’). This cultivar has performed especially well in east-central Iowa. It tends to overbear in some years, significantly reducing the average nut size. However, it is vulnerable to dieback after severe winter low temperatures. Ramets grow vigorously, allowing them to recover well from cold dieback.
