Pseudata and Species-Cross Iris

Species-Cross or Species-x is a hybrid of two different species of iris crossed in the hopes of getting a plant with a wider cultural window. Thus able to grow in many different conditions, also hopefully to bring a new and different pattern or color palette to a plant and bloom.

“Pseudata” are a cross between plants with Iris pseudacorus backgrounds and Iris ensata (Japanese, Hanashobu). The iris world is very fortunate that Hiroshi Shimizu shared many years of his work finding a good pod parent (‘Gubijin’) so all hybridizers could explore the possibilities that this cross may bring to the garden. For details please go to Eye Shadow Iris.

Many have striking foliage for the spring time garden.

These plants emerge very early in the spring, with many having light green to very bright chartreuse foliage; this color adds a shocking brightness to the garden, that I find very pleasing to work with. The coloring will change as the daylight sun gets stronger and brighter, with the plants greening up by bloom time; this is most evident in cloudy maritime zones and may not be as strong elsewhere.

Many of these plants have the vigor and versatility of Iris pseudacorus being able to grow in water, rain gardens, or an average perennial garden given 1-2 inches of water a week; however unlike Iris pseudacorus that is invasive with seed, these plants are sterile or nearly so. If you do get a seed or two, save and plant it, they are special. Please visit our culture pages for further information.
