Bents put plants at the core of its green and community activities, created a three-mile nature ramble and ran a Ready Steady Dig initiative to involve local primary school children in gardening.
Managing director Matthew Bent said: "We have long been committed to initiatives that help the environment and our local surroundings and are delighted our efforts have been acknowledged."
He continued: "We introduced our five Green Footprints several years ago, but over the past 12 months we have really focused on ways in which we communicate these messages to our customers and the award is a great recognition of our efforts."
The award is run by UK Green Forum and the Garden Centre Association. Forum director Mark Long is the scheme's coordinator.
