Yellow Flag Iris

About this plant

Iris pseudacorus, commonly known as Yellow Flag Iris, is a robust and beautiful perennial prized for its brilliant yellow flowers and tall, sword-like foliage. Each bloom features intricate details, creating a captivating display from late spring to early summer, adding a touch of natural elegance to any landscape. Ideal for sunny to partially shaded areas, this iris thrives in consistently moist to wet conditions, making it perfectly suited for pond margins, stream banks, or rain gardens. Its strong, upright growth habit provides excellent vertical interest and structure. Beyond its aesthetic appeal, Yellow Flag Iris is a low-maintenance plant that establishes quickly, providing long-lasting beauty with minimal effort, making it a fantastic choice for both novice and experienced gardeners.

Care & maintenance

Yellow Flag Irises are remarkably easy to care for once established. Trim spent flower stalks to encourage neatness and prevent self-seeding if desired. At the end of the growing season, foliage can be cut back to just above the water level or ground, but this is not strictly necessary for plant health.
