Iris sibirica
Siberian iris (syn. Iris sibirica)
This perennial beauty boasts dark-veined blue flowers, standing proudly on slender stems amidst narrow grass-like leaves. Iris sibirica is a rhizomatous herbaceous plant that graces early summer with its delicate violet-blue blooms, veined with purple on a pristine white base.
These irises are not just a visual delight but also low-maintenance, quick to establish, and easily divided from autumn to spring. Thriving in any soil and basking in the sun, they particularly excel in heavy clay soils, making them a perfect choice for both novice and seasoned gardeners alike.
Where available, we offer these plants in aquatic pots suitable for planting at higher edges of pond margins. Note that these irises prefer not to be submerged and should have their crowns above water level. They are offered as an alternative to our 9cm pots for boggy or moisture-retentive ground conditions.

How to care for Iris sibirica:
Plant in soil that has been improved with well-rotted manure or garden compost and do not allow to dry out, particularly as the plant is getting established. If grown in a container, it will need dividing and repotting every couple of years in spring.
Remove the stems after flowering from the base as this will concentrate the plant's energy into producing new rhizomes. Divide and replant about every three years.

This perennial is semi-evergreen so it can lose some of its leaves in winter. In colder regions or more exposed gardens, it may lose them all, but then fresh new growth appears again in spring.
