Pseudatas: I. pseudacorus crossed with Japanese Iris (I. ensata) Great advances have recently been made in hybridizing Iris pseudacorus with Japanese iris in the pursuit of getting yellow pigment into a Japanese iris form. Yellow has been achieved and some fantastic Eye Shadow signal patterns emerged. These new pseudata iris are hardy to Zone 4 (maybe 3), vigorous growers, especially when grown in or near water (growing up to 5’ tall) and adapt to garden conditions (growing up to 3’ tall). They have 3-4 branches and 10-16 buds, clumps remain in bloom about 3 weeks once established. These new iris are sterile hybrids and will not spread into waterways.
