Yellow Rattle

Seed Packet, Wildflower Plugs, 2024 Seed (Grams) - Free Delivery

Rhinanthus minor. Also known as Hay Rattle.

Yellow Rattle is a critical species for any successful wildflower meadow, it attaches itself to the root systems of numerous different grass species and slows down their growth rate. A reduction in the grass growth rate of 50% can be achieved using Yellow Rattle. This reduced grass growth allows much more space and opportunity within the meadow for a diverse range of wildflower species to establish.

We recommend a planting density for Yellow Rattle plugs of 10 per square metre.

We are now accepting orders for delivery in April 2025 of Yellow Rattle Plugs.

UPDATE 17TH JULY 2024: This year’s Yellow Rattle seed is now ready and orders will be sent out immediately, we recommend a sowing rate of 1g per square metre.

Plants are supplied from the start of April on wards, however yellow rattle seed is available all year round. Yellow rattle plants are an annual root hemi-parasite that require grass to grow. The plant plugs here come supplied with fescues within the plug cells as host plant grasses. Yellow flowers, seeds rattle in inflated seed pods, hence the name ‘rattle’.

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 into soil surface. It is always better to plant directly into the ground and not pot on.
