Iris sibirica 'Silver Edge' Description

Graceful garden plants with refined flowers, and and grasslike foliage

Siberian Iris is a maintenance free perennial with large and colorful booms in late spring and early summer. Narrow grassy foliage forms lush green clumps that stay attractive all season.  Silver Edge is one of our favorites for its robust garden habit and  flamboyant 3" intense blue blooms finely edged in white. Grows 24-30" tall.Terrific as a cut flower.

Siberian Iris bloom after Tall Bearded but before Japanese forms of Iris

How to grow Siberian iris

    Siberian iris thrive in a moisture retentive soil in full sun or part shade.
    Will tolerate lean or poor soil - but need regular moisture
    Keep soil moist the first year until clumps are established.

Designing with Siberian iris

Consider placing Iris in problematic areas such as along a rain gutter or downspout. Plant along moist wet sites, they will grow in shallow water,at the edge of a pond in full sun to part shade. Site along a north facing border.  Certain groundcovers with soft, mounded forms offer contrast and texture against the narrow vertical foliage of Iris. A low growing astilbe with its cut leaf foliage is very attractive at the base of the plant and provide a nice filler between other plantings.  Place groupings of Iris with geranium Rozanne, known of its rambling tendency for a pleasing cottage garden look.  Late spring or early blooming plant combinations include:  peonies, azaleas, digitalis, heuchera Paris or Rave On, lupines, primula or salvia.   Consider planting groupings near shrubs such as Hydrangeas or Knock Out roses.

Soil:  Siberians perform well in most garden soils, but do best if you provide a rich soil containing

Light:  Full sun to part shade.  In hot, southern zones, best to give them afternoon shade

Water:  They prefer lots of water in the spring. Give them about an inch of water a week.

Spacing.  Space 18"- 24"

Fertilizing. Fertilize in early spring with a balance fertilizer such as 10-10-10 and again after bloom season, to encourage growth for next year

Maintenance and pruning:  Remove spent blooms. Divide plants every four year if you see a reduction in flowering performance. Cut back Siberian foliage only after it turns brown and withers in late fall. Then, cutting off all leaves an inch or two above ground level is recommended.
