How to grow

Plant in full sun in well-drained soil. The plant fruits on both primocanes and floricanes, so manage canes to take advantage of both crops, and harvest floricane berries in early to mid-June and primocane berries from August until frost.

Flavor profile

Floricane berries are medium to large and substantial, while primocane berries are larger and juicier in regions with moderate summers. The berries carry an improved flavor with a sugar level rated at 10, just under the popular Ouachita variety.
