Iris typhifolia does very well in far northern Michigan. Its rich color and early bloom, coupled with its wildflowery grace, make it very popular with us and visitors.

This species Iris was discovered in China in 1928. It is closelt allied to Iris siberica and readily hybridizes with that species. The plant is most similar to I. chrysographes having narrow foliage and narrow-petalled flowers. This species is a rich violet-blue. It is one of the earliest Siberian-type iris to bloom.
