There are hundreds of iris species, and countless cultivars, in the world, coming in a wide variety of colors. The blooms put on a spectacular show in May and June each year and the flower stalks should be removed after flowering.
Deadheading is not often regarded as an essential task when it comes to irises, however there is a real importance to doing it. If you deadhead irises, the plant focuses energy into extended blooming and strengthening the rhizome and it can help maintain overall plant health.
