Care tips
It prefers full sun to partial shade and well-drained soils, though it tolerates a variety of conditions. Watering should be moderate, allowing the top layer of the substrate to dry out between waterings, especially in warm climates. A common mistake is planting it in confined spaces without control, as its vigorous growth can become invasive if not properly managed. Regular pruning is advisable to maintain its shape and prevent it from spreading too much.
