It is native to South Africa and knowing this provides the first clue to how to grow plumbago, along with where to grow one
Watering
Plumbago, apart from watering after planting, will need a lot of water when the weather is hot, especially if grown in a pot.
Lights
They grow and bloom best in full or partial sun, but they will tolerate light shade.
