[header] How to grow oleander [title] Grow oleanders in a warm climate. [step] Oleander plants can survive temperatures that occasionally dip below the freezing point, but they thrive in climates that remain above freezing year-round. If you have harsh winters, you may not be able to grow an oleander bush outdoors. 
[substeps] Oleanders will only tolerate temperatures as low as 15 degrees fahrenheit (- 9.4 degrees celsius). At that point, however, the foliage will be damaged.
