About This Flower

Powdery & Soft · Summer–Autumn bloomer

Oleander is the Mediterranean's most luxuriant flowering shrub, clusters of rose-like flowers in white, pink, salmon, red, or yellow blooming non-stop through the hottest, driest months when everything else wilts. It lines highways, fills gardens, and defines the visual character of warm-climate cities from Seville to Dubai.

Symbolism & Meaning

caution, beauty with danger, desire

In the Victorian language of flowers, oleander means “Beware, beauty conceals danger”. One of the most toxic common garden plants, all parts contain cardiac glycosides that can be lethal. Despite this, it's planted ubiquitously in Mediterranean regions, California highway medians, and Middle Eastern gardens for its drought tolerance and continuous bloom. Ancient texts record its toxicity; modern incidents occur when people use oleander wood for cooking skewers.

Did You Know?

Oleander is so toxic that burning the wood releases poisonous smoke, and honey made primarily from oleander nectar can be dangerous. Yet it's one of the most widely planted ornamentals in the world because nothing else blooms so profusely in extreme heat and drought. It can survive desert conditions, salt spray, highway pollution, and total neglect.

Habitat & Environment
