Chief executive Iain Burgess said: "BVG is a truly multi-channel retailer and 33% of our business is through retail outlets.
"We totally support T&M’s retail seed business and we’re fully invested in boosting this vital side of its business – we see it as an area of substantial potential growth".
Thompson & Morgan head of operations Mark Tibbenham said: "We will not be leaving our valued retailers in the lurch! A key part of BVG’s interest in purchasing Thompson & Morgan was to enhance its retail offering, and we’re already working together to do just that."
BVG says it markets through six "key channels" - "traditional mail order, ecommerce, newspaper reader offers, daily deal and online marketplace partners and B2B distribution".
