Southern Highbush Blueberry Cultivars from the University of Florida

Figure 1.

Today there are more blueberry cultivar choices available for Florida growers than ever before, but in every case, cultivar selection involves weighing the advantages and disadvantages of a cultivar relative to the grower’s needs. Unfortunately, there are no perfect cultivars suited for every location and management system. This 10-page fact sheet categorizes southern highbush cultivars into four groups: major cultivars, secondary cultivars, new options, and historical cultivars. Proper cultivar selection is critical to a successful blueberry enterprise, and growers should seek information from multiple sources, including their local county Extension office. Written by J.G. Williamson, J.W. Olmstead, G.K. England, and P.M. Lyrene, and published by the UF Department of Horticultural Sciences, April 2014.

Florida’s Commercial Blueberry Industry (HS742/AC031)

gure 1. Southern highbush blueberry planting with bark beds and drip and overhead irrigationThe Florida blueberry industry has grown rapidly because Florida growers can produce high-quality fruit when few fresh berries are available and berry prices are high. Although southern highbush blueberry acreage has expanded significantly in Florida, Georgia, California, and Mexico during the last several years, better cultivars and improved cultural practices have increased grower production efficiency during the last several years, with promising production trends for the future profitability. This 4-page fact sheet was written by J. G. Williamson, J. W. Olmstead, and P. M. Lyrene, and published by the UF Department of Horticultural Sciences, February 2012.
