Yellow Rattle Seeds

Yellow rattle is a grassland annual with yellow, two lipped flowers, the upper lip with two white or purple teeth. Behind the flower the joined sepals inflate to form a green bladder sometimes tinged with red.

Flowering occurs from May through to August/September followed by a seed capsule which rattles within the now brown and papery bladder. The majority of seed ripens in mid to late July and the rattling of the fruit within the bladder was said to indicate that the meadow was ready to be cut for hay, hence its other common name of hay rattle. Seeds are usually harvested in August and available for sowing from August to October.

Growing Information:
Yellow rattle seed must be sown in autumn (any time from mid August to late October) as it needs a prolonged period of chilling through the winter to trigger its germination the following spring. Prepare for sowing by cutting the grass very short (25mm) or by grazing very hard, removing grass clippings before sowing. Harrowing, scarifying or raking, prior to sowing, aiming to create up to 50% bare soil, is likely to increase the success rate.

Broadcast the seed on to the prepared surface. Traditional meadow management based around a late July hay cut provides Yellow rattle the best opportunity to set seed, and for its seed to scatter during the process of haymaking.

Our packaging is made from FSC recycled cardboard and environmentally friendly inks. The seed bags are waxed paper or compostable starch to keep seeds in the best condition during storage.
