Neomarica caerulea 'Regina' | Walking Iris | Giant Apostle Iris | Neomarica caerulea 'Regina'
Neomarica caerulea 'Regina' is a striking, clumping perennial known as the giant walking iris, featuring sword-like jade-green leaves and showy violet-blue flowers with yellow banded centers that bloom successively from spring through fall. This upright, rhizomatous beauty produces plantlets on fading flower stalks that root upon ground contact, naturally spreading to form colonies in moist shade gardens or containers. Its fragrant blooms, salt tolerance, and minimal care make it perfect for borders, mass plantings, or tropical accents.
