Care tips

It requires full sun for optimal flowering and prefers well-drained, poor to moderately fertile soils, avoiding waterlogging. Watering should be moderate, allowing the substrate to dry slightly between waterings, although it tolerates short periods of drought once established. Sowing directly into the ground after the last frost is ideal, as it does not tolerate transplanting well. A common mistake is over-fertilization, which can promote leaf growth at the expense of flowers.
