How Much Sun Does an Oleander Need

They grow and bloom best in full sun, but they will tolerate light shade. Oleanders are considered hardy in USDA plant hardiness zones 8 through 10, but they are sometimes damaged by frost in zone 8. The shrub usually recovers, even if killed nearly to the ground.

Do Oleanders like sun or shade?

Oleanders do best in full sun but will tolerate partial shade; too little light will cause the plant to get a leggy, open look and reduces flowering. If you’re looking to create a “green wall” with your oleander plants, they should be planted at 5 to 7 foot intervals.

What conditions do Oleanders like?

Good light is essential for oleanders to produce flowers. Indoors, site your oleander in a conservatory, porch, or cool room in bright light or outside in a sheltered spot that gets sun for all or most of the day.
