Nerium 'Oleander': Calypso
Nerium oleander, also known as Oleander, is a rapidly growing rounded, broadleaf evergreen, woody perennial shrub native to Europe and Asia. It grows 5-20 ft tall and 6-10 ft wide. Oleander blooms in late spring to late summer. The flowers are fragrant and showy and appear on new growth, so refrain from pruning after early fall to avoid removing next year’s flower buds. It is intolerant of temperatures at or below 32 degrees F and may be damaged by frost during the winter. Prune back frost-damaged and dead branches once winter passes. Regular light pruning after flowering improves its shape. This shrub is highly deer and salt-tolerant, including salt spray, so it works well in coastal gardens. Its large size makes it an ideal choice for use as a screening plant, foundation plant, or in the back of a border.
