What does Gladiolus look like?
Gladiolus plants grow from rounded corms covered in brown, fibrous layers. Their upright stems bear narrow, sword-like leaves with a waxy surface that sheds rain. The flowers form on tall, one-sided spikes and can be small or large, depending on the species or hybrid. Each flower has six petal-like tepals, fused at the base into a tube, with colours ranging from pink, red, purple, white, cream to orange. Commercial varieties often have large, showy blooms.
Where does Gladiolus come from?
Gladiolus is native mainly to southern Africa, especially the Cape Floristic Region, with additional species in tropical Africa, Asia, and Mediterranean Europe. The genus was first described in 1753. Over time, many species have been discovered, and formerly separate genera are now included. Gladiolus spread worldwide as a garden and cut flower, with most hybrids tracing back to African species.
When and how Gladiolus blooms
Gladiolus flowers grow from corms, which are planted in spring in temperate zones. The plants need moisture during the growing season and are usually lifted and stored over winter where winters are cold. Propagation is by cormlets or seed, but it takes several years for new plants to flower. Large-flowered hybrids may need staking. Some hardy types can survive cold winters if the soil is dry.
How Gladiolus is used
Gladiolus is popular in gardens and as a cut flower for arrangements. It is given as a gift for August birthdays and fortieth wedding anniversaries. The flower is also a symbol of Punjab and is associated with victory in some traditions. Gladioli have appeared in music, literature, and public events, such as the International Four Days Marches Nijmegen.
Kinds of Gladiolus
There are nearly 300 species and many hybrids, with most wild species found in southern Africa. Main hybrid groups include 'Grandiflorus', 'Primulines', and 'Nanus', bred for larger flowers and a range of colours. Notable cultivars like 'Robinetta' have received horticultural awards. Natural and artificial hybrids are also known.
