Thompson & Morgan working with the RHS

Thompson & Morgan is pleased to be able to offer the only seed ranges endorsed by the Royal Horticultural Society in the UK.

Established in 1804 - a mere 50 years earlier than Thompson & Morgan - the RHS is the UK's leading gardening charity and one of the world's leading horticultural organisations, reknowned for prestigious events such as the RHS Chelsea Flower Show as well as its own gardens, website and publications.

Thanks to its expertise and extensive trial work over the years, the RHS can provide a font of plant and growing knowledge. By choosing plants that have been given an Award of Garden Merit (AGM) gardeners have the reassurance that they are growing plants that have been trialled and assessed by experts in UK garden situations.
