Iris sibirica

Ruffled creamy white standards are yellow-green at the base. Falls creamy white with buttery yellow signals and yellow-green veining. 

Bred by Currier McEwan, legendary Maine hybridizer based in Harpswell, a pioneer in iris breeding who brought many award-winning varieties to market. This was all accomplished in his later years after he retired from practicing medicine. When he passed away at 101 years old, he was the eldest resident of Harpswell. Don’t let anyone tell you gardening isn’t good for you. This cultivar won the Royal Horticultural Society’s Award of Garden Merit, 1996. Zone 3.

Additional Information

Iris

Iris is the name of the Greek goddess of the Rainbow and of this large genus of beautiful flowers in a range of sizes and a rainbow of colors. Growing from bulbs or fleshy rhizomatous roots, irises are superb for cutting and borders. For all iris, “standards” are the three erect petals; “falls” are the three pendent, reflexed or spreading petals. The blaze of contrasting color is the “crest,” “blotch” or “signal.” Most irises prefer sun or dappled shade with moderately fertile well-drained soil. All bulbous irises we stock prefer dry soils when dormant in summer.

Siberian Iris

In late June, delicate flowers dance above tall slender slate-green foliage that looks good all summer. Tolerates most conditions, but performs best in rich moist acid soil.

Plant 18" apart in full sun or partial shade. Give them room to spread, and divide clumps every few years.

Herbaceous Perennial Plants

When you receive your order, open the bags and check the stock immediately. Roots and crowns should be firm and pliable. Surface mold is harmless and will not affect the plant’s future performance. Store plants in their packaging in a cool (35–40°) location until you are ready to plant. If it’s going to be awhile, you can pot up your perennials.

Do not plant bare-root perennial plant crowns directly outdoors before danger of frost has passed. Wet and/or cold conditions for an extended period may cause rotting.
