Why the Caesar's Brother Siberian Iris?

During those wonderfully pleasant and mild days between spring and summer, Caesar’s Brother Siberian Iris takes the stage. It opens its exquisite flowers. The deep violet-blue blossoms carry themselves with grace and style, hovering above sword-like foliage that looks handsome all season. No finer picture could be created than a planting of Caesar’s Brother with classic partners that also bloom at this special time: Roses, Peonies, Hardy Geraniums, Clematis, and Catmint. A pond provides additional opportunities for beautiful vignettes—Caesar’s Brother luxuriates in the boggy soil at the water’s edge. Wherever it goes, this beloved Spirit brings an easy elegance with it!

New varieties come and go, but this selection from the 1920s remains one of the most popular Irises on the planet. Caesar’s Brother was bred by F. Cleveland Morgan of Montreal. Morgan wasn’t a plant breeder by trade, but a passionate amateur gardener whose family owned a chain of Canadian department stores. To produce the new plant, he crossed an Oriental Iris with a closely related Siberian Iris. Although the resulting plant is a hybrid, it is usually just referred to as a Siberian Iris. He did name one of the offspring ‘Caesar’, in case you were wondering, but nobody grows that one anymore!

How to use in the landscape?

Cut flowers make a house a home. Plant some extra Caesar’s Brother Siberian Iris, so you’ll have plenty for cut arrangements. The long, straight stems and intricate, showy blooms make this Spirit tops for cutting. Harvest them right after they open.

How To Plant

Give Caesar’s Brother Siberian Iris a spot where it can soak up the sun all day. Regular water is a must for lush, healthy foliage and abundant flowers. As you may guess by the name, this Spirit is at home in cold regions and is less well suited to hot and sticky parts of the country, although Caesar’s Brother is a better performer in the southern U.S. than most Siberian Irises. Leave seedpods standing for winter interest. Cut plants down in late winter to make way for new shoots to emerge in the spring.

How To Water

Water as soon as they arrive! Irises need to be watered regularly to maintain evenly moist soil for proper establishment in the landscape.
