(80-90 days. Heirloom. INDETERMINATE) The potato leaf plants produce fruits with shoulders that are a dusky, dark mahogany color that blends deeply into its flesh. Some years if leaf coverage is not particularly dense and the sun is intense, the shoulders can take on deep-green tinge. Black Brandywine was bred in the 1920s by Dr. Harold Martin, a Pennsylvania dentist. It is very similar in all other characteristics to Pink Brandywine – the fruits are relatively large, globe to oblate shaped, and offer an excellent, complex full flavor.
