Varieties of Siberian iris

Siberian iris 'Sky Wings'

Siberian iris 'Sky Wings' boasts elegant blooms with a sky-blue hue, resembling bird wings in flight. This hardy perennial thrives in moist, well-drained soils, often gracing the edges of water bodies where it can reach up to 3 feet tall. Its narrow, arching leaves and sturdy stems support the delicate flowers that come to life in late spring, offering a striking display in cooler climates.

Siberian iris 'Strawberry Fair' is a vigorously-growing cultivar of the Iris sibirica species. It is known for (and named for) its glorious ruffled, magenta-pink and lavender-pink blooms that have white edging. Foliage is upright, blue-green. It is trouble-free, low maintenance, and deer-resistant, making it a popular choice for gardeners.

Siberian iris 'Super Ego'

Winner of the very prestigious Morgan Award, siberian iris 'Super Ego' 's pale blue flowers become darker into the summer season, giving them a uniquely ombre look. Also producing attractive, bright green foliage, this variant was cultivated as a hybrid and named after the plant's beauty, probably giving it something of a "super" ego! Siberian iris 'Super Ego' is beloved for its long-living blooms, grass-like leaf blades, and centerpiece ornamental value.

The name of siberian iris 'Tropic Night' refers to its velvety, violet flowers with contrasting yellow centers. This plant also has thin, bright green leaves and tall stems. This cultivar was produced as a cross between Iris sibirica 'Caesar' and an unknown iris.

One of the largest siberian iris cultivars, the siberian iris 'Sparkling Rose' is considered distinctive for its long flower form with widely arched petals.
