Nerium oleander Splendens (Oleander)
Tough and vigorous, Nerium oleander 'Splendens' (Oleander) is a spectacular evergreen shrub that produces an abundance of large clusters of fragrant, funnel-shaped, soft pink double flowers. Interestingly, some petals may display white streaks of freckles, adding further beauty to the plant. 'Splendens' will bloom year-round in warm climate areas, and throughout summer in other areas. Thriving with little care, this beautiful flowering shrub features a bushy, rounded to vase-shaped habit, and its evergreen foliage of leathery, lance-shaped leaves clad the branches throughout the year. Native to the Mediterranean region, this attractive shrub is heat and drought-tolerant once established and will grow especially well in seaside gardens, tolerating salt spray and wind.
- Grows upright with an open habit to 6-12 ft. high (180-360 cm) and 8-12 ft. wide (240-360 cm).
- Easily grown in average, medium moisture, well-drained soils in full sun. Will grow in poor soils and tolerate coastal conditions. While Oleanders are very drought tolerant, their floral show is more impressive if regularly watered.
- Deer and rabbit resistant
- Great for flowering hedges, cottage gardens, coastal gardens, Mediterranean gardens, city gardens, or large containers.
- Virtually disease free, but watch for red spider mites, scale insects, and mealybugs.
- Prune lightly as needed to shape after flowering
- Propagate via semi-hardwood /softwood tip cuttings
- All parts are highly toxic if ingested. Contact with foliage may irritate the skin.
