General Description

Sweet iris is an attractive, clump forming perennial with semi-evergreen, sword-like leaves of soft gray-green. This Croatian native is best known for its fragrant, lavender-blue flowers that appear in late spring to early summer. Like all bearded iris, these have three distinct upright petals (standards) and three distinct downward facing petals (falls) that have are lined with fuzzy "beards" at their bases. The beards are actually designed to draw in pollinators, particularly bees. Sweet iris prefers well-drained soil and full sun but can tolerate partial sun. This very hardy plant is best suited to large, sunny perennial borders and cottage gardens.
