About Oleander
Oleander (Nerium oleander) is a tough, fast-growing evergreen shrub from the Mediterranean and Southwest Asia, producing abundant clusters of showy flowers in white, pink, red, or yellow throughout the warm season. Its narrow, lance-shaped leaves and dense branching make it a popular choice for screens and highway plantings, though all parts are toxic. Starting at $14.95.

Care essentials
Light
Grow oleander in full sun for the best flowering and densest growth; partial shade is tolerated but results in a leggier, less floriferous plant. NE Florida's abundant sun suits it perfectly.
Water
Oleander is highly drought-tolerant once established — water occasionally during extended dry spells but avoid overwatering, as it thrives even on poor, dry soils. Established plants along NE Florida roadsides need virtually no supplemental irrigation.
Soil & Fertilizer
Oleander tolerates nearly any well-drained soil — sandy, clay, alkaline, or saline — with minimal fertility requirements. One application of a balanced granular fertilizer in spring is sufficient; over-fertilizing encourages vegetative growth at the expense of flowers.
