Care tips
It prefers full sun to partial shade for optimal flowering and well-draining soil, although it is tolerant of a variety of substrates. Regular watering is required to keep the soil moist, especially during dry periods, but avoid waterlogging as its tuberous roots are sensitive to rot. A common mistake is not deadheading spent flowers, which can reduce the production of new blooms and allow excessive self-seeding if not controlled. Fertilize lightly during the growing season to encourage abundant flowering.
