Green Roof & Coastal Wildflower Plug Plants Mix

Create vibrant, wildlife-rich landscapes in challenging sun-exposed or coastal locations with the Green Roof & Coastal Wildflower Plug Plants Mix. Carefully selected for drought-prone soils, shallow substrates, windy coastal sites, and green roofs, this mix of UK native wildflowers provides seasonal colour, supports pollinators, and establishes resilient habitats for insects and birds.

Each plug is grown in a 40cc cell, ensuring strong root development and fast establishment. Perfect for green roof installations, coastal gardens, brownfield regeneration, urban green spaces, and exposed embankments, this plug mix thrives where traditional seed sowing often fails. Its species are adapted to poor soils, salt-laden winds, and drought conditions, offering long-lasting visual impact with minimal maintenance.

A minimum of 10 hardy species is selected from the mix, including Yarrow, Kidney Vetch, Oxeye Daisy, Birdsfoot Trefoil, Musk Mallow, Cowslip, Viper’s Bugloss, Dark Mullein, Self Heal, and Bladder Campion. Species selection may vary slightly depending on seasonal availability to ensure strong, healthy plants ready for planting.
