Iris sibirica (Siberian iris). This species is easy to grow. It will produce a large range of colours, heights and blooming times. They will prefer to be grown in a moist well drained soil that is moderately rich; they will thrive in full sun or partial shade.
They are fully hardy, but some groups may thrive only in specific growing conditions. All irises are best planted in late summer and early autumn. Outdoors you can grow them in well drained, fertile, neutral or slightly acid or alkaline soil in full sun to lightly dappled shade. In order for irises to thrive, most of them need long, hot summers. Irises that require protection from rain or frost should be grown under glass.
