Wildflower Turf

Founded in 2003, Wildflower Turf has pioneered and developed a soil less growing system which has transformed the concept of turf growing. Wildflower Turf is currently working with a number of organisations to help create wildlife friendly environments for species such as bees, butterflies, voles and slow worms, to name a few. These organisations include The Natural History Museum, Sainsbury’s, The Environment Agency and Natural England. A number of councils throughout the country have used the turf to improve parks and open spaces in their areas, and many more have made enquiries for future projects. In addition the turf is specified by many architects for both green roofs and landscaping projects as a simple way of guaranteeing a wild flower meadow and the ecological benefits this brings.
