Yellow FlagDescription
Our native yellow Flag iris is very vigorous and can be invasive if not contained.
Top tip: If planted into a small container on a shelf, it will blow over in the wind. Divide and re-pot regularly every 2 years.
Flowers: Late May/June
Height of plant: 50-90cm from crown. .
Propagation: Harvest seeds when ripe in August/September as the pods yellow and begin to open up.
How to plant: Plant into a 5lt or 10lt 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 crown 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 5-25cm.
