The tree of this variety is weak-growing or semi-dwarf, which makes it suitable for small gardens and intensive planting. The variety is early-ripening, with harvest occurring in August.
The fruits are medium to large in size, oval or round in shape. The skin is colored from dark red to blue-violet and covered with bloom; the flesh is yellow. The variety is self-incompatible and requires the presence of pollinators such as Imperial, Opal, Purple Gage, or Seneca.
The variety is intended for dessert use, suitable for fresh consumption, as well as for making jams, chutneys, and baked goods. It is characterized by high yield and stable fruit bearing.
