Iris sibirica 'Double Standard' - 2026

Iris sibirica 'Double Standard' is an eye-catching Siberian iris that makes a bold statement in the garden. Its blooms are a rich violet-blue with ruffled petals that show delicate veining and striking golden-yellow signals at the base of the falls. The flowers are large and elegant, with a layered appearance that adds depth and movement, while the slender green foliage forms attractive clumps that bring structure to planting schemes. In groups, the combination of colour and form creates a dramatic and long-lasting display.

This hardy perennial thrives in moist but well-drained soils and is best grown in full sun to partial shade. Flowering in early to mid-summer, 'Double Standard' is valued for its reliability, low maintenance, and ability to attract bees and butterflies. It works beautifully in borders, naturalistic meadows, or near ponds and streams, where its upright form and striking blooms enhance both formal and informal designs.
