Iris Pseudata
"Pseudata" is the term for an iris resulting from a cross of I. pseudacorus X I. ensata. Modern varieties are typically 30"-45" tall and strong-growing plants with multiple flowers per stalk. Many exhibit a strong "eyelash" pattern in their signal. Since most of these crosses generally result in sterile hybrids, there is no danger of such plants becoming invasive, as is possible with I. pseudacorus.
Modern pseudatas grow in ordinary garden conditions or in the perennial border. They require ample moisture, especially when they are transplanted. Good culture will increase height, branching, flower size, and quantity of bloom. These irises will grow and bloom better if planted in full sun. If the soil is clay, the addition of organic matter will help to loosen it. If the soil is more sandy, the organic matter will help in water retention as well as adding nutrients. Depending on what is available, till in ample amounts of manure, hay, straw, peat moss, etc. If using hay or straw you may need to add high nitrogen fertilizer to compensate for the nitrogen tied up in the decomposition process. If your pH is too high, it can be lowered by the addition of granular ferrous sulfate, aluminum sulfate, or agricultural sulfur.

Mt. Pleasant Iris Farm has been doing amazing work with Pseudatas. They encourage the use of soilless container potting medium with a ‘Miracle-Grow’ 6 month feeding. They use it not only for the patio container, but also for the germination of the seed of their breeding lines.
A one gallon container is the minimum, for a single or double fan plant. This will keep the plant for one growing season, requiring yearly transplanting.
