Growing directions
WARNING: ALL PARTS OF THIS PLANT ARE HIGHLY TOXIC IF INGESTED — site it away from areas where livestock, pets, or small children graze on foliage, and never burn the trimmings, since the smoke carries toxic compounds. Root cuttings in spring or set out container plants after the soil has warmed, in ordinary well-drained soil in full sun; oleander shrugs off heat, drought, salt spray, and poor soil, which is why it lines highway medians and beachfront properties across the Gulf Coast and Southern California. Clusters of single or double flowers in white, pink, red, salmon, or yellow appear almost continuously from late spring through fall on new wood, so prune lightly right after a bloom flush rather than in late winter. Cold snaps below the high teens can kill it to the ground in zone 8, but established plants typically resprout vigorously from the root crown.
