The company worked with volunteers to lay the wild flower turf at Weald & Downland Open Air Museum in Singleton, Chichester, to help raise awareness of the county's regional biodiversity and sustainability.
The museum is now the second UK site to benefit from a donation of soil-less turf, following laying in Battle last month.
Managing director James Hewetson-Brown said: "The blend features 30 different flower seeds and four types of grasses. We grew more than we needed for the Olympics so this is an ideal way to extend the turf's benefits to the wider community and provide a lasting legacy."
