Heavy, consistent yield with an attractive, light blue, high quality berry. The fruit is firm and has a good crunch when eaten fresh and freezes well.

Branches may droop to the ground when laden with fruit and require the use a simple trellis as support. Stunning red/gold foliage in the autumn. Self fertile but as with all blueberries, cross pollination with another variety will increase yield.
Plant 1.5m (5ft) apart in rows 2m (6ft) apart.
Plant in an open sunny spot in a moist acid, but well-drained soil. Can also be successfully grown in pots with ericaceous compost.
