Gladioli are beautiful flowers that grow from corms. They are a favorite of many gardeners because of their tall stems adorned with many bright flowers. Due to their height, they make a very attractive flower for the back of the border. They can be seen from a distance, and are ideal for creating a colourful summer display. All our gladioli are sold as corms. Simply make a hole in the ground, place them in and cover over with soil then firm down and water.
