Care tips
This species is extremely adaptable and low-maintenance. It prefers locations with partial to full sun exposure, although it tolerates dense shade, where its growth will be less vigorous. Watering should be moderate once established, as it is drought-tolerant, and it thrives in a wide range of soils, from sandy to clayey, as long as they have good drainage. A common mistake is to underestimate its vigor and spreading capacity, so pruning is recommended to control its size if grown in limited spaces.
