Care tips
It prefers full sun exposure for optimal flowering, though it tolerates light partial shade in very hot climates. It requires well-drained soil, rich in organic matter, and regular watering during the growing and flowering period, keeping the substrate moist but not waterlogged. It's important to dig up the corms in autumn in areas with cold winters and store them in a dry, cool place until the next spring. Avoid excessive nitrogen fertilization, as it can promote foliage growth at the expense of flowering.
