IRIS sibirica Swans in Flight (Swans in Flight Siberian Iris) This later blooming white variety will certainly turn your head when it blooms in early summer. Extremely large, 5″ ivory white flowers are wider and fuller than the classic ‘White Swirl’. Lemon yellow signals put the finishing touches on this elegant plant. When planted in mass, it looks like a blanket of white flowers.

A Northern Sunset perennial, it prefers rich, moist to well-drained soil in full sun to part sun.
