Cultivation Notes

Yellow Oleander, or Thevetia peruviana  (also known as Cascabela thevetia) is a beautiful tropical shrub native to Mexico, Central and South America. All parts of this plant are considered to be highly toxic, including the seeds, leaves and milky white latex sap, as are many other members of the Apocynaceae Family of plants. They can also self-sow and be considered invasive when growing conditions are optimal. They are stunning ornamentals, the narrow leaves and fragrant tubular blossoms bloom much of the year, and the thick growth can provide an excellent hedge or privacy screen. They can be pruned to be a large shrub or a small tree, and need regular water in very hot climates during the summer months.

Good drainage is essential for this plant to thrive. It needs low amounts of supplemental water once established in moderate climates, and regular water in hotter climates. Irrigate by watering deeply and then allowing the top several inches of soil to dry between waterings. This encourages the plant to send roots deep into the earth in search of moisture, helping it to become established, prevent root rot, build drought tolerance, and resilience to heat and cold. The length of time between waterings will vary depending on your growing conditions and environment.
