Care tips
It requires full sun for optimal flowering and prefers well-drained soil, rich in organic matter. Water regularly during its growing and flowering period, keeping the substrate moist but not waterlogged; reduce watering once the leaves begin to yellow. Plant the corms 10-15 cm (4-6 inches) deep with similar spacing and be sure to dig them up in autumn in climates with cold winters to protect them from frost. A common mistake is not providing adequate support for the tall flower spikes, which can cause them to bend or break in the wind.
