Yellow Rattle ‘Rhinanthus minor’

Also known as Hay Rattle. An annual root hemi-parasite that requires grass to grow, the plants here come supplied with fescues within the plug cells as host grasses. Yellow flowers, seeds rattle in inflated seed pods. Slows the growth of grass down substantially allowing both greater quantity and variety of wildflowers when used within a meadow. Plants are supplied from the middle-late of April onwards, however seed is available all year round. Plugs are best planted in groups of 3 after mowing grass. Please do not remove the grass out of the plugs. Ensure plugs are well firmed in. It is always better to plant directly into the ground and not pot on.
