Siberian irises flower well in a warm sunny area or semi shade in well-drained, fairly dry soil.

These Siberian irises grow best in the garden. The plant has thick rhizomes which should be planted as soon as possible upon receipt. Prepare the ground and thoroughly loosen the soil. Improve heavy garden soil by mixing in some sharp sand. Make a mound in the planting hole and lay the thick roots of the iris along both sides of the mound about 1 cm below ground level. Fill the hole with soil and press firmly down. Water immediately after planting. The spacing of the rhizomes should be roughly 25-30 cm.

Siberian irises in the garden

Siberian irises are a group of large-flowered irises that really dislike wet soil – dry, permeable is perfect. These irises grow best and are at home when planted in a raised bed against a south wall. However, Siberian irises will also flower profusely, planted along a sunny border.

Siberian irises are hardy perennials. The soil can normally be moist to slightly dry rather than too wet. Cut off faded flower stems completely and remove any unpleasant-looking leaves. The sword-shaped, greyish green leaves die back towards the end of summer, but new leaves appear once again in autumn. In winter, cover the plants with a layer of leaf litter or conifer branches. Cut off all the leaves in spring, give it a good feed and you will soon see new shoots appear.

Siberian irises should be rejuvenated

For profuse flowering, we recommend rejuvenating your Siberian irises after 4, 5 or 6 years. Dig up the rhizomes in August. Cut off the younger parts using a sharp knife while making sure that each part has a growing shoot Replant these young pieces and the following year the beautiful flowers appear again.

Siberian irises come in many wonderful varieties.
