Brazil nuts, cashews, chestnuts, filberts/hazelnuts, macadamia nuts, pecans, pistachios, shea nuts and walnuts. Brazil nuts, cashews, hazelnuts (filberts), and pecans are common constituents of mixed nuts. Hazelnuts (filberts), walnuts, pecans, and chestnuts are all wind-pollinated temperate-zone nuts. Commercially available hazelnuts, or filberts, are currently produced only in Oregon from the European hazelnut. The family seat was The Filberts in Aston Tirrold, Berkshire (now Oxfordshire). Similarly, the Nuttery consisted entirely of filberts that appear to have been planted around 1900. Filberts are particularly effective in blending work, usually of a figurative nature.
