Large, semi-ruffled white blooms. Some Siberian Iris aficionados rate 'Gull's Wing' as the best of the white-flowered varieties.
This lovely Iris has been in commerce for almost a century. The flowers are white, of course, leaning toward ivory.
Iris breeders are dramatically changing the range of colors, heights, and bloom times available in this group. Siberian Iris often begin to flower in late May, but the peak of bloom here in Connecticut is in the first half of June. Their thick roots drive down deeply, which makes them drought resistant (though they also thrive in damp soil) and great plants for holding steep banks in place. Each clump becomes huge, and when a group of them grows together, weeds can't grow in between. After bloom, the grassy leaves stand erect and green through the growing season. Siberian Iris struggle in the desert Southwest.
