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.
