Nerium oleander Red — Red Oleander Seeds
All parts of this plant are poisonous to multiple species (e.g., dogs, cats, humans, horses, cattle, etc.).
Bold, timeless, and steeped in ancient symbolism, Nerium oleander Red is a flowering evergreen shrub that brings dramatic color and Mediterranean elegance wherever it grows. Revered since antiquity and planted along roads, courtyards, and palace gardens for centuries, oleander has long symbolized endurance, beauty, and resilience in hot, challenging climates.
From late spring through fall, Red Oleander produces abundant clusters of deep crimson to rich ruby-red flowers, each bloom softly luminous against glossy, dark green, lance-shaped leaves. The flowers are pleasantly fragrant, especially in warm evening air, adding another layer of sensory appeal. In favorable climates, blooming can continue almost nonstop, making this one of the longest-flowering ornamental shrubs available.
Cultural & Historical Significance
Oleander has appeared in art, poetry, and architecture across the Mediterranean, Middle East, and Asia for thousands of years. It was commonly planted along ancient Roman roads and aqueducts, admired for its ability to thrive in heat, drought, wind, and poor soils. Red-flowering forms, in particular, have been associated with passion, strength, and vitality. Even today, Nerium oleander remains a signature plant of classic coastal and desert landscapes.
Wildlife & Ecological Relationships
While Nerium oleander is not a larval host for North American butterflies, it is a primary larval host plant for the Oleander Hawk-moth (Daphnis nerii), a spectacular moth species found in parts of Europe, Asia, Africa, and occasionally observed elsewhere. The flowers are visited by bees, butterflies, and moths for nectar, particularly in warm climates where flowering is prolonged. The dense evergreen structure can also provide shelter for beneficial insects and small wildlife.
