Additional Information
Siberian Iris
Beardless flowers float above the foliage. Slim yet sturdy stems bear up to 5 blooms, good for cutting. Tall slender foliage in clumps looks great all summer grouped in borders or naturalized in colonies. Wonderfully hardy, low maintenance, easy to grow; tolerates clay or poor dry soil, but performs best in rich moist acid soil.
Plant 12–15" apart in full sun or partial shade, with rootstock just below soil level. Give them room to spread; divide tight clumps and clumps with open centers if flowering decreases (you may need an axe).
