NATAL PLUM
(Carissa macrocarpa)

Best traits—This fast-growing evergreen shrub produces dense foliage, making it an effective barrier plant. Throughout the year it produces fragrant star-shaped white flowers similar to those of star jasmine; these are followed by red or purple fruits. Drought-tolerant, this plant does well in a variety of light and soil conditions, and grows up to 7 feet high and 10 feet wide.

Growing tips—Plant in full sun to light shade. It is frost-tolerant to 29 degrees and will do best in cold weather if placed near warm south- or west-facing walls.




GIANT TIMBER BAMBOO
(Bambusa oldhamii)

Best traits—Also known as Oldham’s bamboo, this dense-growing, low-maintenance clumping variety is a vigorous grower that can reach 45 feet in height. Its wide canes and large, attractive leaves provide quick cover.

Growing tips—Plant in full sun to part shade. When purchasing, look for plants with crowded roots, as they grow fastest when confined. For the quickest growth and the largest size, water frequently and feed monthly with a high-nitrogen fertilizer; cut back for smaller, slower growth.




SOUR ORANGE
(Citrus aurantium)

Best traits—This ornamental evergreen tree produces highly aromatic white flowers in late winter and clusters of orangish-red fruits in fall that remain on the tree year-round. It can grow to 30 feet high and is a favorite of bees, butterflies and birds. Although its juice is too sour to drink, its fruit makes a tasty marmalade.

Growing tips—Plant in full sun in well-draining soil. Do not let the soil dry completely. Use caution when handling, as this tree has spines. Basin or flood irrigation is advised to avoid salt buildup around the roots. Fertilize three times a year.




YELLOW BELLS
(Tecoma stans)

Best traits—This long-blooming shrub puts out lush foliage and large clusters of bright-yellow blooms from mid-April through November. A tropical-looking plant, it can reach 15 feet high and 10 feet wide and can be trained as a tree. Hummingbirds flock to this fast grower.

Growing tips—Plant in full or reflected sun in soil with good drainage. Prune frost-damaged branches in late winter or early spring. Note: Tecoma stans var. angustata is the hardiest variety.
