Thompson & Morgan's license expires on 30 June, 2017.
The joint-branded vegetable and flower seed ranges for the 2017/18 season each have an Award of Garden Merit (AGM).
Packets will appear on two separate single-sided displays — one for flowers and one for vegetables — with bespoke point-of- sale material.
The AGM range will launch from May 2017 and will be available for delivery into retailers from August 2017.
This launch means Mr Fothergill’s has become the preferred partner for licensed seed and seed gifting products for the RHS.
Mr Fothergill's joint managing director David Carey said: "We are delighted to be working as the preferred seed partner for the RHS. The packaging and display that we have developed together will really lift this range in-store and will complement our existing offer. We look forward to launching the Mr Fothergill’s and RHS Award of Garden Merit range in the coming months, and developing other products together in the future."
RHS licensing Mmanager Cathy Snow said: "Mr Fothergill’s has a well-earned reputation for its passion to supply the very best quality gardening products, underpinned by the highest levels of customer service, a reputation reflected in its presence in thousands of gardening outlets. We are delighted to be able to partner with this exceptionally well-regarded company."
