Pseudata

Iris pseudata 'Tsukiyono'  has soft lavender petals with a dark violet pattern around the yellow signal, radiating to the petal edge. This is a midseason bloomer for Iris and will be at peak in early summer. 'Tsukiyono' has a great upright habit perfect for adding vertical interest to the middle of the border. The translation of the name from Japanese is 'Moonlit Field'.

Pseudata Iris are a cross between Iris pseudocorus and Iris ensata ("pseudata" is combination of both names). Iris pseudata creates the best of both species-the hybrid vigour, the higher bud count, colour blend, eye signals, a longer season of bloom, and the plants are sterile and do not seed around.

Growing and Maintenance Tips

Pseudatas grow in ordinary garden conditions and are best planted in full sun.  They require ample moisture, especially when they are transplanted. Good culture will increase height, branching, flower size, and quantity of bloom. All beardless iris prefer a rich soil with ample organic matter. If the soil is clay, the addition of organic matter will help to loosen it. If the soil is sandier, the organic matter will help in water retention as well as adding nutrients. Planting in a small depression (2.5- 8 cms below the average soil level) will help the plant receive extra water during rains. Avoid planting in areas where prolonged cover of ice may smother the plants. After planting keep well-watered until the plant is established and new growth begins to appear. A heavy mulch helps to conserve moisture as well as reduce weeds. It will also offer protection to the roots of the plant over the winter.
