Sapphire is a low-chill southern highbush blueberry that is recommended mainly as an early-season variety in areas south of I-4 where blueberries can be commercially grown. In Alachua County, Sapphire reaches 50% open flower about February 18. First commercial harvest of Sapphire in Alachua County averages about April 16 and harvest is complete before May 15. Ripening is more concentrated on Sapphire than on Sharpblue. Fruit color and size are comparable to Sharpblue and Misty. The picking scar is dry and fruit are firm. Sapphire is not as vigorous as Sharpblue and tends to set large numbers of flower buds which may require thinning for adequate vegetative growth. The plants may be slow to establish during the first 2 to 3 years after planting. Because of its low vigor, Sapphire should only be planted on good blueberry land or in pine bark beds. Overhead irrigation is recommended for freeze protection wherever Sapphire is grown. From Ocala north, Sapphire has been replaced by varieties with greater vigor, such as Star, Millennia, Jewel, and Emerald.
