Designed for challenging, sun-exposed sites, the Green Roof / Coastal Wildflower Plug Plants Mix contains hardy, UK native wildflowers ideal for dry soils, green roofs, and coastal locations. This mix features species adapted to thrive in shallow substrates and windy, salt-laden environments—making it the perfect solution for rooftop gardens, cliffside plots, urban developments, and seafront landscaping projects.
Each plug plant is grown in a robust 40cc cell to promote strong root systems and rapid establishment. Whether you are creating an ecologically rich green roof, regenerating a coastal verge, or enhancing biodiversity in a dry open space, this mix will provide long-lasting visual appeal and vital habitats for bees, butterflies, and other pollinators.
