What You Need to Know About the Oleander Plant – Apocynaceae – Nerium Oleander

Originating from the Mediterranean to western China, oleander is a large evergreen shrub with leathery, dark green leaves, grown for its display of beautiful, often fragrant, funnel-shaped flowers. These are produced in terminal clusters and can be single, semi double or fully double, according to the variety in shades of white, cream, yellow, apricot, salmon, cop­per, pink, rec, carmine, and purple. Individual flowers can be up to 2 in. (5 cm) across and are borne in groups of 6—8. This is an ideal plant for a sunny windowsill while it is small, and for a well-lit conservatory or sun-room as it grows.

Size: Height up to 6 ½ —7 ft. (2—2.2 m).

Light: Dire it sunlight.

Temperature: Normal room from spring to fall, but below 60°F (15°C) in winter for the rest period; winter minimum 45°F (7°C).

Moisture: Keep thoroughly moist from spring to fall, barely moist in winter. Allowing the plant to dry out as the flowers form will result in the buds being shed.

Feeding: Provide standard liquid fertilizer every two weeks in spring and summer.

Propagation: Take tip cuttings, to 6 in. (15 cm) long, in summer, rooted in either soil or water.

Special needs: The whole plant — sap, flowers, and seeds — is very poisonous, so handle with extreme caution, and wash hands thoroughly after contact.
