TB Cosford, or Brownfield Tokolyi Cosford or Tokolyi Cosford, was selected in Australia. It is a vigorous hardy tree with good steady yields. It’s major use is for blanched kernels and is suitable in confectionaries. The mid-brown nuts have a thin shell and are medium-sized.
Hazelnuts prefer mild summers and cool winters (temperate climate) and do best when a number of conditions are met: annual rainfall of over 750 mm or additional irrigation especially while establishing after planting; and protection from wind and high summer temperatures.
- Pollination Group: Male and female flowers on the same tree don’t always flower at the same time so it is best to have other varieties present in particular: Barcelona, Tonda Di Giffoni, Lewis, Wanliss Pride, Red Aveline.
- Uses: eating, cooking, roasting
- Harvest: nuts fall (Feb to March)
- Chill requirement: Requires about 1,200 hours of 5 to 7 deg C. Female flowers are vulnerable to frosts below -5 deg C especially when opening.
- Features: Australian-selected variety for late summer to early autumn nuts
