Widely cultivated as an ornamental shrub or as an informal hedge in warm climate areas, Nerium oleander is a beautiful medium-sized evergreen shrub. Tough and vigorous, it produces abundant clusters of single or double flowers in shades of red, pink, white, cream, yellow or purple. It will bloom year round in warm climate areas and will flower all summer in other areas. Thriving with little care, this native to the Mediterranean region is heat and drought-tolerant once established, and will grow, especially well in seaside gardens, tolerating salt spray and wind. A tender plant, Nerium oleander can, however survive light frost.
