Care tips
It requires full sun for abundant flowering, although it tolerates some partial shade in very hot climates. Watering should be moderate, allowing the top layer of the substrate to dry out between waterings to prevent waterlogging, which is its main enemy. Use a well-drained substrate rich in organic matter. A common mistake is overwatering, which leads to root rot and lack of flowering.
