Siberian Iris is a popular and attractive perennial that is native from regions in central Europe through to Russia. It is an adaptable herbaceous plant that develops substantial tall clumps of linear blade-like green foliage. In early summer it displays many beardless iris flowers that appear on tall stems. These may be white, purple, or violet-blue.
Siberian iris grows best in sunny locations and fertile soil with average drainage, but tolerates slight waterlogging. It is quite cold tolerant and slowly spreads, so clumps should be divided every three years or so. Enjoy this vigorous perennial in any large, sunny flower bed. They look most impressive when planted in masses and flower and overall grow best where spring and summer are not overly hot.
