All 153 stores will stock the premium amenity grass seed mixtures. Launched in August 2014, Green Velvet has seen "significant" growth following instore promotion and the appointment of three sales agencies.
Barenbrug UK marketing manager Paul Warner said: "Green Velvet now has UK-wide distribution. A fantastic achievement in less than a year. We continue to invest heavily in the brand, to promote an outstanding product that is flying off the shelves at Wyevale."
The range of six premium varieties includes hard-wearing and fast-germination ‘Action Hero’; and ‘The Emergency Life Saver’, a quick-fix mixture for emergency repairs.
Green Velvet is also being trialled at Notcutts.
