Growing perennials means lots of color when you plant gladioli. There is something about a bare piece of ground that suddenly breaks with foliage at an amazing rate and then bursts in a splendid show of flowers a few weeks later. Gladiolus are not actually bulbs but are considered perennial corms.
Easy to Grow Gladiolus Corms Add Appeal to any Garden Setting
I remember having my lunch outside one year watching each day as these beauties kept getting taller and taller. There was so much anticipation for the flowers to finally appear. And they did not disappoint! Gladiolus is one tough heat loving perennial bulb.
A corm is a rounded underground storage organ that is present in plants such as crocuses, gladioli, and cyclamens, consisting of a swollen stem base covered with scale leaves. And flowers of course!
There are so many varieties that can be grown and they are easy in most gardens. I love gladioli because they make spectacular cut flowers and attract bees and butterflies like crazy to my garden.
Here is how to grow them.
- Plant gladioli corms in the spring after danger of frost has passed.
- Loosen the soil to about 12 to 15 inches. (these are tall plants and need a good root system.
- Add organic matter to the hold and plant the bulbs about 3-6 inches apart and water well.
- Glads are best grown in a garden that gets full sun
- Now is the time to stake if you are planting tall varieties, so that you don’t damage the plant with a stake later.
- Days to flowering is about 90 days.
- If you like cut flowers, cut the stems when 1 or two flowers are open. The others will continue to open when place in water.
- Be sure to leave some of the leaves after cutting the flowers. The corms need them to provide nutrition for next year’s growth.
- Zones 7 or 8 need just a layer of hay or straw. If you live in colder zones, you will need to dig up the corms, dry them and store them at 35-45 º F until the spring and then plant again.
Here are some of the gladioli blooms that graced my garden this year.
This pretty yellow gladiolus was a late bloomer for me this year. It bloomed in my test garden in late July.
Close up of the yellow one. I was so surprised to see it flowering when my others had died.
This beauty had the prettiest combination of white, pink and yellow. The bees loved it!
Another pink one from my front border. This bed gets sun all day long and my gladioli bloom beautifully there.
Deep red variety in my test garden. This one did not grow quite as tall as my others but had bigger blooms.
Very lovely deep pink and white one. Needed staking or it flopped over.
