Plant Iris sibirica 'Swans In Flight' where you can enjoy its elegant, beardless iris blooms rising above a tidy clump of narrow, grasslike foliage. This Siberian iris is a dependable perennial for mixed borders and moisture-retentive beds, and it is especially at home near water features where soil stays evenly moist.

Give it full sun to part shade. In hotter climates, a bit of afternoon shade can help keep plants looking their best. While it appreciates consistent moisture for peak performance, established clumps can handle short dry spells. Aim for fertile, organically rich, well-drained soil that does not bake hard in summer; adding compost at planting time helps hold moisture without creating soggy conditions.

Expect mature stems about 30-36 inches tall, with a clumping habit that gradually widens over time. Water during prolonged dry periods, especially in spring and early summer, and keep a light mulch layer to conserve moisture. After flowering, you can leave seedpods for seasonal interest or remove spent stalks for a neater look. Cut back foliage in late fall or early spring before new growth begins.

To keep blooming strong, divide crowded clumps every few years. Lift and split the rhizomes, then replant divisions at the same depth and water well until re-established. With simple care, this cultivar can provide years of graceful color and structure in your garden.
