Description This fast growing evergreen shrub can reach up to 20 ft (6.1 m) tall but is usually seen trimmed at 6-10 ft (1.8-3.1 m). It forms a rounded mound to about 10 ft (3.1 m) wide. It is a tough, versatile plant with showy summertime flowers in white, red, pink, salmon and light yellow. Leathery, lance shaped leaves range from about 4-10 in (10.2-25.4 cm) long, depending on variety and are a bright green. Oleanders have a tendency to become leggy - overgrown individuals should be pruned as needed to maintain a nice shape. A popular variety is 'Petit Salmon' which is a dwarf that grows to only 4 ft (1.2 m).
Location Nerium oleander is native to northern Africa, the eastern Mediterranean basin and southeast Asia. Oleander prefers dry, warm climates and may naturalize in such areas.
Culture Light: Bright sun, some shade is acceptable.
Moisture: Versatile, can survive both dry and wet soils. Fastest growth occurs when provided moisture in times of drought.
Hardiness: USDA Zones 8-10. Easily grown in warm humid climates, like Florida and the Gulf coast, oleander is recommended for USDA Zones 8-10. It will survive some frost and temperatures to 15-20ºF (-9.4 - -6.7ºC) but foliage will be damaged. Some varieties are hardier than others.
Propagation: Semiripe cuttings are best rooted in summer. Also by seed, but selected cultivars may not grow true to form. Pests: Aphids and scale may be a problem (more likely in humid climates). Also attacked by a caterpillar that will strip a plant in a matter of days.
Features The oleander is a tough durable shrub that is inexpensive and easy to grow in most situations. Abundant, beautiful flowers are produced in many colors and some varieties are delightfully fragrant. New homeowners appreciate oleander's satisfyingly fast growth rate and ability to quickly green up a bare lot.
