Irises are highly popular flowers in many gardens and for good reason – they’re hardy, reliable, and beautiful. Many gardeners prefer them because, in addition to being graceful and colorful – after all, the word “iris” means “rainbow” in Greek -- they attract butterflies and hummingbirds.
Among the over 300 species of irises worldwide, Siberian Irises in particular are popular because they are among the easiest to grow in a temperate climate like ours, easily adapting to USDA Plant Hardiness Zones 3 to 8. While the name might sound like they prefer a colder climate, they are in fact a group of hybrid flowers developed from two blue-flowered Asian species. The Siberian Iris (Iris sibirica) sports amazingly long lasting flowers in a cool and consistent spring. Too much rain and heat will wilt flowers prematurely. The most common is ‘Caesar’s Brother’ (photo).
