The production of gladiolus corms covers about 900 hectares; this puts it in second place among the summer-flowering bulbs. In terms of the number of hectares used for its production, the gladiolus is close to the narcissus. The number of hectares has decreased somewhat, mostly due to the great interest in lilies. Traditionally, this very colourful bulbous plant has been used for cut flower production in countries with temperate and warm climates, as well as for planting in gardens. These very tall plants have bright, appealing colours: red, purple, yellow, orange and white. In recent years, breeding has considerably increased the colours and flower shapes available in the commercial assortment.
For the production of corms (gladioli are not true bulbs), the growers plant the small corms and “cormels” in the spring (April) and harvest them in the autumn (Mid October/ mid November) when they have grown larger.
