Plant care & info
Genus: Iris
Common name: Iris
Origin: Over 300 species native to temperate areas of the northern hemisphere.
Conditions vary greatly among species. Generally, Iris thrive in full to part sun. Some species are more shade tolerant. All Iris thrive in well drained soil. Bog species (I. cristata, I. pseudacorus, I. sibirica) can grow in full sun and permanently damp soils.
Most Irises prefer regular water during the growing season, and little to no water when dormant. There is also bulbous Iris such as the Dutch Iris which bloom in March (plant bulbs in fall.)
Irises can be food for slugs and cutworms (as are most plants.) Non-bog species are prone to rot if they are perpetually soggy. Bearded irises may not bloom if the rhizomes are not on top of the soil or if they are over crowded. The most common disease tends to be leaf spot.
Siberian and Japanese iris require little to no maintenance. Bearded Iris benefit from dead heading of individual flowers and a leaf trim in summer. In fall, cut back and clean up old foliage to keep tidy and help prevent leaf spot.
Good cut flower. Deer resistant. Attracts butterflies. Tolerates moist soil.
Divide bearded iris in late summer after flowering. Siberian and Japanese iris can be divided in late summer and fall. Some species can grow from seeds planted in fall.
Their pointed blades of foliage lend a strong vertical feel in the gardens, which can be a great structural and textural contrast with perennials and shrubs. They look great in the garden as a lone seasonal focal point or planted in swaths.
This page focuses on non-bulbous bearded, Japanese, and Siberian iris—plus a few other jewels in the genus.
