Care tips
It requires full sun for optimal growth and abundant flowering, at least 6 hours daily. Watering should be moderate, allowing the substrate to dry out between waterings to prevent waterlogging, as it is susceptible to root rot. It prefers well-drained, sandy or slightly clayey soils, with a neutral to slightly alkaline pH. A common mistake to avoid is overwatering, especially in winter, which can be fatal to the plant.
