Growing and Maintenance Tips
Siberian Iris are the most trouble free of the Iris species. Grow them in full sun in rich soil that is moderately acidic. Working some peat moss in the soil will help to make the soil more acid and moisture retentive. They will take a couple of years to establish and then can be left until flowering is not as profuse. Divide in August when necessary.
