The Oleander has green foliage and inconspicuous red flowers, with a moderate amount of conspicuous brown fruits or seeds. The greatest bloom is usually observed in the summer, with fruit and seed production starting in the summer and continuing until fall. Leaves are retained year to year. The Oleander has a moderate life span relative to most other plant species and a rapid growth rate. At maturity, the typical Oleander will reach up to 12 feet high, with a maximum height at 20 years of 12 feet.

The Oleander is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by bare root, container, cuttings, seed.
