Also known as Blenheim Orange, this apple variety was reported by S.R.S. Gray as being grown in the islands, but "erroneously called Dutch Mignonne". While there is a separate variety known as Dutch Mignonne, it is also considered an alternate name for Blenheim. We have not yet located either Blenheim or any other Dutch Mignonne still growing in island orchards. Blenheim is an English apple, originating in Woodstock, Oxfordshire, England before 1818. The fruit are large and russetted. Like most russets it is a late apple with a rich, nutty flavor. Blenheim is considered a good cooking apple, breaking down into a smooth sauce. It is a triploid and does not produce viable pollen.

Dutch Mignonne, when it is not a synonym for Blenheim is a Dutch variety that originated well before 1771 (when it was introduced to England). The fruit are large, round, orange apples with red stripes. They are late ripening and long keeping.
