The Duke Blueberry forms an upright bush between 4 and 6 feet tall and wide. It is very decorative, with pretty, white flowers in spring and bright orange and yellow fall colors. That is even before we get to the berries, which are exceptionally large, a light and bright blue, with a sweet flavor and a unique ‘crisp’ bite when raw. This plant is so pretty you can grow it among your flowering shrubs, or in a dedicated food-growing area of your garden. It produces an early crop from late May to early July, depending on your region, and this northern highbush variety is an ideal choice for colder zones.

  • Excellent blueberry to grow in colder areas
  • Early ripening variety ready by late May
  • Very decorative for growing in the flower garden
  • Exceptionally heavy crop up to 20 lbs. from a single bush
  • Self-pollinating, so one bush is all you need

The Duke Blueberry grows well in zones 4 to 7, and it should be planted in full sun or just a little partial shade. The soil should be moist but well-drained, and a steady supply of water is needed for good results. The soil must be very acidic, between 4.5 and 5.5 on the pH scale. If you don’t have suitable soil, grow it in a large tub or planter, using an acidic soil mix.
