Primadonna makes a vigorous, upright bush and tends to be more evergreen than Star and Jewel, possibly because it tends to be more resistant to rust than Star and Jewel. It also tends to flower before it makes new leaves, which can be a serious problem if it does not produce enough early leaves to support development of fruit. It is also somewhat susceptible to root rot and stem blight. It requires 300 chill hour units.
Emerald is a vigorous bush with a growth habit midway between upright and spreading. Flowers open uniformly and it produces abundant leaves even after mild winters. Emerald is very capable of carrying heavy crops. Berries are large and firm with a good picking scar and have a sweet flavor. Color is medium to dark blue. There are no real problems with Emerald, root rot, stem blight and cane canker have not been too serious.[/important]Emerald is a vigorous bush with a growth habit midway between upright and spreading.

Gupton is vigorous and productive and have an upright growth habit. Berries are medium to large in size, with good flavor, color and firmness and have small picking scars. Bloom occurs relatively late. It is highly recommended to plant Gupton with other southern highbush cultivars for cross-pollination, in order to increase fruit set, early ripening, and maximum yields and quality. back to top
Sebring is a vigorous, upright plant with medium to good resistance to the diseases that most often kill blueberry plants in the field in Florida. It flowers and puts on new leaves very early in the growing season and is highly susceptible to freeze damage during February if grown as far north as Gainesville. The heat-unit requirement to go from flowering to ripening is similar to Sharpblue, and is longer than for clones like Star and Millennia. The berry is medium to large, about like Sharpblue. The berry color is dark blue, similar to Windsor. The scar, firmness and flavor are good.
Millennia is medium to high in vigor, with a spreading growth habit, but it not excessively twiggy. It produces a heavy load of flower buds in the fall. The berry is large to very large on well-leafed bushes that are not overloaded. They are grey-blue in color and are very firm with a good picking scar and flavor. Leaves have medium resistance to leaf-spotting fungi but show somewhat below average resistance to stem blight and root rot. back to top
Snowchaser is a low chill variety and is the earliest ripening blueberry. The bush is highly vigorous, produces numerous flower buds and produces high quality berries. It has a growth habit midway between upright and spreading. Berries have good scar, firmness and flavor and are medium blue in color. back to top
Misty (’92) has a low chilling requirement like Sharpblue, but has a greater tendency to retain its leaves through the winter. Misty is more resistant to phytophthora root rot than Sharpblue. It is a vigorous, upright bush. The worst problem with Misty is its tendency to produce far more flower buds than the plant can support. These flower buds tend to sprout before the leaf buds in the spring, and the resulting flowers and fruit inhibit sprouting of the leaf buds. Misty stems that flower and fruit without leaves are also highly susceptible to tip die back, caused by Botryosphaeria dothedia, and can spread rapidly downward, killing the stem and the entire plant. This problem can be minimized by removing flower buds from young plants and by reducing the flowering of bearing plants via pruning in late summer and winter. Berries are large, firm and have good color. back to top
Gulf Coast (’87) loses its leaves by Christmas and has the same chill requirement as Sharpblue. Gulf Coast and Sharpblue flower and ripens at the same time. The berries are large and of good flavor. back to top
Sharpblue (’76-’77) combines a vigorous bush that leafs well in the spring and has good size and excellent flavor. It normally maintains good balance between flower buds and vegetative buds making it easy to prune. Sharpblue is moderately resistant to phytophthora root rot and stem blight. This variety requires cross pollination for greatest earliness, yield and fruit quality. Problems with Sharpblue include susceptibility to various foliar diseases, limited resistance to phytophthora root rot and stem blight and several berry quality problems. There is some tendency for the skin to tear when the berry is picked. Sometimes, the dry corolla tends to remain on the berry through harvest, possibly due to lack of cross pollination and Botrytis flower blight during bloom. Sharpblue often has a long fruiting season, with early berries being large in size and later berries may be much smaller. back to top
Farthing is a very low chill vigorous bush with the bush structure of Windsor, but with more branchiness. The plant makes numerous flower buds and flowers very heavily. Flowering is not as late as for Windsor but later than for Emerald and Jewel. The berries begin to ripen at about the same time as Star, Windsor, and Emerald. Berry firmness is good, and the texture is somewhat but not fully crisp. Berry scar and flavor are good. Farthing is partially self-incompatible and requires cross pollination for full fruit set. back to top
