Iris x germanica 'Pokemon'

Irises should be divided each year after they have flowered, and the flower stems are dying. Divide by splitting each plant with a spade, leaving at least half of the plant in the ground, and then cut back the dying foliage and stems. Lastly, top-dress with bone-meal

Ideally the Iris plant would need to be planted in a sunny spot so that it can receive at least six hours of sun a day as well as being planted in well drained but moist soil. They do well near water but should be at least 6 inches above water level. Plant with part of the rhizome exposed, as "baking" in late Summer sun will help flowering in Spring. Avoid hoeing around the base of the plants as the roots are near the surface and easily damaged. Do not mulch, as this can block light, and create damp that can rot the rhizome.

Most bearded irises flower in Spring to early Summer, but some tall bearded varieties are remontant (ie have a second flowering period) in late Summer.
