Siberian Irises are super reliable and dependable perennials in your garden with colorful flowers in shades of blue, violet, yellow, white, and pink. The flowers have a graceful appearance as they sit atop stong, sturdy stems in springtime. They have sword like foliage that forms a grassy-like appearance and is quite attractive long after the flowers have gone for the season. Siberian iries require little maintenance, prefers regular soil moisture and are quite drought tolerant once established. They're often less prone to disease than other types of irises. If you notice flower production low after 4-5 years, then you may want to divide the rhizome and replant in the spring or fall. These hardy perennials are right at home in your flowerbeds, borders, waterside plantings, and in your patio containers. This collection includes 1 each of Double Standard purple, Butter and Sugar yellow/white, and Not Quite White. The cultivar of Not Quite White is the shorter of the bunch topping out at 18" tall while the other two will grow to around 30" tall.
