  • Provides year-round interest, with red foliage in the fall and red twigs in the winter.
  • Is self-fertile, but cross-pollination produces a better crop -- creating larger yields of larger berries. So it is best to plant more than one variety with the same bloom time 4--6' apart.
  • Blooms April–May, with white flowers covering the plant.
  • Yields ripe fruit midseason, producing a consistent crop of 15 lbs. each summer.
  • Has a chill hours (CU) requirement of 800. (Chill hours are the average hours of air temperature between 32° and 45° F in a typical winter season.)
  • Grows in a rounded shape.
