Blue Flag Iris (Iris versicolor) is a hardy, moisture-loving perennial that brings a splash of vibrant blue-violet to the garden. It thrives in permanently moist or boggy soils, even likes our poorly drained clay. Great for planting along ponds, dams, or water features. With regular irrigation, it can also grow happily in standard garden beds, rewarding you with masses of graceful flowers in spring and summer.

Native American medicinal use of blue flag

Traditionally valued by North American First Nations peoples, Blue Flag has been used in herbal medicine for centuries. Modern herbalists prepare the dried root to support the liver, encourage detoxification, and promote healthy circulation, digestion, and fluid balance. Poultices made from the root have also been applied to ease rheumatic joints.

The part used is the root.

👉 The root must be harvested and dried before use because, when fresh, it contains compounds that can cause nausea or irritation. Drying reduces these effects and allows the herb to be prepared safely for traditional use.

In the garden

I love pretty medicinal herbs! Grow something useful and still have a garden; this one looks best when mass-planted. It would also be a great plant in a history-inspired herb garden showcasing native American herbs or colonial 19th-century gardens.

 

How to grow blue flag

In Australia, Iris versicolor grows best in cool to temperate climates with reliable moisture, including Tasmania, southern Victoria, the NSW highlands and at least as far North as Port Stephens, where it flowers in spring. 

The plant prefers moist soil and may struggle in tropical heat or hot, dry inland conditions.
