Yellow rattle (Rhinanthus minor), is a wildflower native to Ireland and Europe and a key species for restoring wildflower meadows. This wildflower is known for its yellow flowers that when dry, rattle in the wind and its ability to suppress the growth of taller, more dominant plants. This ability give the plant nick name "The Meadow maker". Yellow rattle is a semi-parasitic plant, as it steals nutrients and water from other plants. The plant's roots penetrate the roots of grasses and other meadow plants, reducing their vigor and allowing a greater diversity of wildflowers to thrive. This makes the yellow rattle very important plant for restoring meadows.
In addition to its role in meadow creation and restoration, yellow rattle is also a valuable source of nectar for pollinators such as bees and butterflies. The plant's yellow flowers bloom from June to September and provide a vital source of food for these insects during a time when other nectar sources may be scarce. The yellow rattle seeds are also an important source of food for several species of birds, including the reed bunting and the goldfinch. This makes yellow rattle an important species for supporting biodiversity and maintaining healthy ecosystems.
Unfortunately, yellow rattle and other wildflowers are currently at risk due to habitat loss and the intensification of agriculture. Over last few decades, meadows have been converted to fields of monoculture crops or grass field for cattle. It is estimated that in UK and Ireland we have lost 97% of wildflower meadows since 1930s.
To protect and conserve yellow rattle and other Irish native wildflowers, it is important to restore meadows and other wildlife habitats. Planting wildflowers, organic gardening and farming, and managing land in a way that supports wildlife. Additionally we need to protect and conserve the few wildlife habitats we have left.
How to sow Yellow rattle: mow grass on shortest setting and rake out as much as possible to expose bare soil. Sow seeds in 2 direction for even distribution. Rake lightly and roll or walk over seeds to achieve better contact with soil.
When to sow Yellow rattle: Sow in autumn as yellow rattle needs cold period for germination. If you missed this period no need to worry. You can also sow in the spring if you buy Gardens for Wildlife Yellow rattle seeds as the seeds are stored in cold temperatures over winter.
Help us plant more native trees
Every purchase on our website will help us to buy and grow more native trees of which we have so little in Ireland. You can also help by sharing our content, products, or donate additional trees here. You can also help us during the planting days. Every small help will be greatly appreciated.
