Southern Highbush Blueberry Cultivars from the University of Florida

HS1245

Blueberries are native to eastern North America and are one of the few crop plants that originated here. The woods and swamps of Florida are populated with at least eight wild blueberry species, including highbush blueberry (Vaccinium corymbosum), rabbiteye blueberry (Vaccinium virgatum), and evergreen blueberry (Vaccinium darrowii). Wild blueberries are present nearly everywhere in Florida, except in areas where soil pH is above 6.0. This publication provides historical background on southern highbush blueberries (SHB) and information on specific UF/IFAS cultivars that can be a helpful resource for SHB growers. The intended audience is primarily Florida commercial blueberry growers but also commercial growers in other locations growing UF/IFAS cultivars. Table 1 provides information on plant and berry characteristics for selected cultivars.

Leek Cultivation Guide for Florida

HS1388

Leek (Allium porrum L.) is a member of Amaryllidaceae, a family with ornamental crops, like amaryllis, and with vegetable crops, like onion. Members of this family typically grow umbels composed of showy and radially symmetric flowers with six distinct to connate tepals. The parallel-veined, simple, entire leaves are flat and arranged basally. The black or blue seeds usually contain the pigment phytomelan (Castner 2004) (Figure 1). There are two types of leek typically grown: common leek and Chinese leek. Common leek can reach three feet tall and has a width of two inches (MacKenzie 2018). Chinese leek is thinner, shorter, and has stronger flavors (Figures 2 and 3). Both leeks are monocots that do not produce bulbs and are grown for fresh-market production. The edible portion is the cylinder of bundled leaf sheaths, commonly called a stem, stalk, or pseudostem (Danto 2013; Swamy and Gowda 2006).

Butia odorata: Pindo Palm

ENH264

The pindo or jelly palm was formerly known by the scientific name Butia capitata. However, recent research has shown that the correct name for this palm should be B. odorata. This small, single-stemmed, feather-leaved palm is widely grown in warmer parts of the US due to its unusual cold tolerance. It is considered hardy down to about 10°F or USDA zone 8A (see http://planthardiness.ars.usda.gov/ PHZMWeb/), but can survive in protected sites in zone 7B. While they survive in south Florida, pindo palms grow much better in cooler, less humid climates. They are considered to be intolerant of salt spray. This species has not been assessed for invasiveness by the UF/IFAS Assessment of Non-native Plants in Florida’s Natural Areas.

Sugar Apple Growing in the Florida Home Landscape

HS38

Scientific Name: Annona squamosa L.

Common Names: annon, custard apple, sweetsop

Family: Annonaceae

Origin: The sugar apple is indigenous to tropical America.

Relatives: cherimoya (A. cherimola), soursop (A. muricata), custard apple (A. reticulata), pond apple (A. glabra), ilama (A. diversifolia), atemoya (A. cherimola x A. squamosa)

Distribution: Sugar apples are mainly grown in the tropics. In Florida, sugar apple production is restricted to warm locations along the lower southeast and southwest coasts. However, home landscape trees may be found along the southeastern shore of Lake Okeechobee and in warm, protected locations along the lower east and west coasts.

Importance: Sugar apples are a common fruit tree in the home landscape throughout the tropics and have been widely planted in South Florida.
