This giant cowslip has tall flower stems above rosettes of large, mid-green leaves. The nutmeg scented, sulphur yellow flowers are strongly fragrant. This lovely plant holds the RHS AGM (Award of Gardening Merit).
Top tip: Can be grown in consistently damp soil, but also on the marginal shelf to give an architectural focus.
Height of plant: 20-60cm from shoot-root junction. When given space to grow, readily forms dense, attractive clusters of leaves and flowers.
Propagation: Divide after flowering.
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, when planted, the shoot-root junction of the plant will be 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 0-10cm.
