Iris How Audacious Siberian Iris

Aptly named, Iris ‘How Audacious’ is an extraordinary Siberian iris that grows 24 to 42 inches tall, blooming from early to midsummer, just after the bearded iris season. Each long, sturdy stem holds multiple bicolored blooms that rise elegantly above a vase-shaped mound of arching, grass-like blue-green foliage, which remains vibrant into fall. The ruffled petals are a dramatic blend of reddish- and blue-violet, accented by intricate white veining and a sunny yellow center. These bold, luxurious blooms make stunning additions to early summer floral arrangements.

An Iris sibirica variety, commonly called Siberian iris, ‘How Audacious’ is a hardy perennial suitable for Zones 3-9. Its rhizomatous growth makes it an excellent choice for naturalizing along pond edges or in wild gardens, though it thrives just as well when grouped in flower beds or borders.

Known for its easy care and love of moisture, ‘How Audacious’ grows best in sunny to partially shady locations with moist, acidic soil. Once established, it tolerates drier conditions, making it versatile for a range of garden styles. In hotter climates, provide some afternoon shade to encourage optimal blooming. Fertilize in spring with a nitrogen-rich blend to promote growth and remove spent flower stalks to keep your garden tidy and prevent self-seeding.

Plant ‘How Audacious’ roots in spring, spacing them 36 inches apart and 1 to 2 inches deep. Soak rhizomes rhizomes in water overnight before planting to encourage strong growth.
