Gladiolus Flower Bulbs

In the genus gladiolus there is about two hundred and fifty species.  They are in the Iridaceae or iris family.  The majority of gladiolus are native to southern Africa.  Most are hybrids.   

The flower stems of gladiolus can have at least seventeen flower blooms, all facing the same direction.  Gladioli are mainly grown to make beautiful flower arrangements.  Learn how.  They come in a wide range of colors, and make great cut flowers to use for any occasion.  When cutting the flower stems, it is best for the bulb to leave at least four leaves attached. 

When used for their floral beauty in gardens, stakes may be needed to keep them upright or they can be grown where there is little wind to blow the gladiolus flower over.  Pick the old flowers off as they wilt, to help the keep the view showy.  To prolong the blooming time span, plant corms up to ten weeks apart. 

Gladiolus can be miniature to jumbo sizes.  They can grow forty inches or taller taking up little space with their long slender leaves.  The most popular sizes are miniature and large.  The larger the corm is in its size, the larger the plant will grow. 

Gladiolus bulbs should be dug up sometime before the first freeze after blooming.  After they are dug up, the old bulbs that are attached underneath the new bulb needs to be removed.  The corms should be free of dirt and dried for a few weeks before storing to help prevent them from rotting.  Put the corms to be stored in a vented container such as a old pair of pantyhose or a cloth bag sideways.  Hang the container in a dry cool place to replant the next year.  Do not let the bulbs freeze. 

Most gladiolus corms reproduce by growing cormlets during its first six years.  The young cormlets take two or three years to bloom.  The gladiolus flower likes to be located in full sun, and do best in moist well drained soil.  They bloom during July and August.  Depending on the species, gladiolus will grow in zones four through ten.
