I love my Iris sibiricas massed. In my own private garden I have whole beds of them. Their clumps of narrow strap like leaves are more architectural than any grass. Their elegantly under-engineered, tall flowering stems provide essential vertical lines in the unstructured tumult of late Spring. And their brown seedheads raised aloft like the tips of rusting rifles provide safeguard into winter…
Iri sibiricas can be planted in sun or shade. They will thrive in any soil from the heaviest to the lightest.
Bare root Iris sibirica or Iris spuria. Plants are lifted all the year round. 10 working days must be allowed for lifting and splitting. If a plant has a 2litre pot listing this can be despatched all year round within 4 working days.

Iris Sibirica Care Notes
The Siberian iris is native to Turkey where it grows in swampy ground. In cultivation it is an amenable plant. It is unfussy as to soil and will grow in anything from the heaviest clay to the lightest sandy soil. Happy in full sun, it also thrives in shade. After planting Siberian Irises needs no special care, being disease free and untroubled by pests.
Siberian Irises are particularly suitable for use in London gardens, where the heavy soil and frequently shady conditions preclude the use of Bearded Irises. Their architectural clumps of foliage give substance to any herbaceous border. Iris sibiricas look handsome planted with Ligularias, Hostas, Brunneras, Phlox, Euphorbia Fireglow, Lythrums, Filipendula, Eupatoriums, Rheums….. Don't chop down the dead flowering stems in August. Iris sibirica seed heads look good well into the winter.
Siberian irises make large clumps of architectural foliage and should be allowed a spread of at least 60cm. They flower in June-July. Iris sibiricas are easy plants untroubled by pests and disease. They are deer and rabbit proof and salt tolerant.
