The description from 1916 Livingston's Seed Catalog says: "A very productive, early purple sort, uniform in size of fruit, free from cracks, and does not blight easily. Fruit large and smooth. Vines vigorous and quite productive. Quality excellent." First offered in the Seed Savers 1995 Yearbook by D. C.
