Description
Iris sibirica is elegant and shapely, with tall narrow leaves and flower stems topped with delightful, but sadly short lived, blue iris flowers.
Top tip: .Grow in a basket on a shelf in your pond where the soil surface is just at water level so that the soil doesn’t ever dry out.
Flowers: June/July Exquisite rich sky blue
Height of plant: 30-50cm from crown
Propagation: You can divide these after they have flowered, but we have found that the best time to divide is once the young shoots have become established in April/May
How to plant: Plant into a 5lt planting basket using heavy garden loam or Westland Aquatic Soil and place on a shelf in the pond. Fill the planting basket to a depth so that the top of the rhizome at the base of the plant is level with the rim. Hold the plant securely and fill in with soil all around the roots, pressing the soil down very firmly until the planting crate is almost filled to the brim. For aesthetic purposes, the soil can then be top dressed with no more than 1cm of pea gravel.
Recommended planting depth: The planting depth for this plant measured from soil surface to water surface and not including any gravel dressing is 0cm.
