Lowland Calcareous Grassland Seed Mix
This wildflower seed mix has been developed to support the creation of lowland calcareous grassland habitat (g2a) on free-draining, lime-rich soils such as chalk and limestone downland, slopes, and unimproved calcareous pastures. The mix is dominated by characteristic calcicolous wildflowers and fine, low-vigour grasses, making it well suited to long-term grassland restoration and Biodiversity Net Gain delivery. Species selection has been informed by NVC CG-series calcareous grassland communities.
The mix performs best under light grazing or low-intensity cutting. Final vegetation will vary depending on soil depth, fertility and management, with optimal results achieved where nutrient inputs are avoided and long-term low-intensity management is maintained.
