Bluetta: Bush is short, compact, low growing, spreading, and of medium vigor. Fruit is medium sized, soft, and blue-black with fair flavor. Fruit can hang on the plant for a long time. Consistent production may be a problem. Winters well and does not break dormancy too early. Moderately resistant to mummy berry disease; highly susceptible to anthracnose and red ringspot virus.
Earliblue: Bush is vigorous and upright spreading. Fruit is large, firm, and light blue with fair flavor. Not recommended commercially in many areas because of erratic fruit set. Fruit does not drop easily when ripe. Plants have some resistance to powdery mildew.
Weymouth: Old variety (from 1936) that has been widely grown. Fruit is a bit soft, of average size, and has a mild flavor. Resistant to many diseases.
Chanticleer: Very early, but the early bloom time can cause this variety to be very susceptible to spring frosts. Yields tend to be biennial. Early plantings not deemed successful by commercial growers. Needs a well-drained soil. Highly susceptible to anthracnose.
Polaris: A cold-hardy release from Minnesota (half-high). Moderate productivity and average berry size, but has very good flavor and aroma. Not self-pollinating.
Sunrise: Moderately vigorous bush, tall, and relatively upright. Fruit is similar to that of Bluetta in size and color, but firmness and flavor are superior. Resistant to red ringspot virus.
