Care tips

It requires full sun for optimal flowering and well-drained soil, preferably rich in organic matter. Watering should be regular, especially in hot and dry climates, keeping the substrate slightly moist but avoiding waterlogging, as it is susceptible to root rot. To prolong flowering, deadhead spent blooms. A common mistake is planting it in excessive shade, which results in fewer flowers and leggy growth.
