Harlequin blue flag (Iris versicolor), Quebec's official floral emblem since 1999, is a native perennial found from Manitoba to Newfoundland in Canada, as well as in several eastern U.S. states. Native to marshes and wet plains, it also adapts well to garden beds with good drainage, needing watering only during dry spells. This graceful plant reaches up to 65 cm in height and forms dense clumps of sword-shaped, blue-green leaves that are shorter than the flower stem. Its stunning blue-violet flowers, accented with touches of yellow and white, appear early in spring, adding a vibrant touch to gardens.

Ecological Roles
Harlequin blue flag plays a vital ecological role, especially in wetland areas, where its rhizomes help stabilize banks and prevent soil erosion. Its flowers attract a variety of pollinators, including bees and some butterflies, which benefit from its nectar and pollen. Its ability to thrive in wet environments makes it an ideal plant for water gardens and riparian landscapes, supporting local biodiversity while adding a natural decorative touch.

 

Harlequin blue flag seeds require cold stratification to ensure germination. See the cultivation notes below for more details.

Growing Notes | Seeds - Harlequin Blue Flag

For harlequin blue flag seed germination, both scarification and cold stratification are necessary before sowing.

Scarification: Soften the hard seed coat by lightly scratching the surface between two sheets of sandpaper, then soak the seeds for 24 hours in water that has previously been boiled for 5 minutes.

Stratification: Mix the seeds with a moist substrate (such as vermiculite, perlite, or sand) containing sphagnum moss and place them in a plastic bag in the refrigerator for 90 days.

After stratification, sow the seeds in their desired location as soon as the temperature is suitable or when the seedlings have reached a height of 4 to 6 inches.

Alternatively, you can sow outdoors in the fall, and germination will occur the following spring or later.

Seedlings will require regular watering until they are established. Mature plants prefer moist soils and thrive even in 2 to 4 inches of standing water. Blooming typically begins the second year after planting.
