About this plant
Neomarica northiana, commonly known as the Walking Iris, is a striking plant known for its sword-shaped green leaves with distinctive yellow markings and beautiful iris-like flowers. It is called 'walking' because new plantlets form at the ends of flower stalks and can root when they touch the ground, allowing the plant to spread naturally. It is often grown as an ornamental plant indoors or in gardens for its attractive foliage and flowers.
