I live in South Africa, in the KwaZulu Midlands. This plant has invaded my property and taken over at least 4000m2 of the 9000m2.
I would suggest container planting only especially in areas that they flourish.
It takes continued maintenance to pull out and cut down and they keep coming up every where - plant with discretion.
Beautiful evergreen and stunning show when flowering but invasive in ideal environment and left unchecked.

Red Cestrum, unlike the Orange flowering type, is readily available. On the US West Coast it is evergreen, somewhat rangy and almost ever-blooming. Fairly drought tolerant but flowers better with some summer water. Grows fast and the arching branches will overshadow other plants nearby if you don't stake/prune. Tough and vigorous (mine flowered within 6 wks of being planted from a 1 gallon can), hardly noticed being transplanted after doubling in size, unlike many plants I could name! Very self-cleaning, no pest problems so far, a very good perennial that deserves more notice.
