RHS Award of Garden Merit

Royal Horticultural Society (RHS) Potato Trials 🏅

We are proud that 24 of our potato varieties already hold the prestigious RHS Recommended: Award of Garden Merit (AGM) recognising their outstanding performance, reliability, and garden value.

This season, we are delighted to be working with the Royal Horticultural Society, with even more of our varieties being entered into their trials. These trials help identify the very best potatoes for home gardeners, assessing everything from yield and flavour to disease resistance and overall performance.

We're excited to see how our varieties perform and look forward to sharing the results with you as they become available.

What is the RHS Recommended: Award of Garden Merit?

The RHS Recommended: Award of Garden Merit is one of the most respected endorsements in UK gardening. Awarded by the Royal Horticultural Society, it recognises plants that have performed exceptionally well in trials and demonstrated excellent garden value. To receive an AGM, a variety must be reliable, widely available, reasonably resistant to pests and diseases, and deliver consistently good results for gardeners. For potato growers, an AGM is a strong indication that a variety has proven itself through rigorous testing and is well worth considering for the garden or allotment.

What are the 2026 trials about?

For this trial RHS are focusing on salad potatoes growing in containers, and they will be assessed by a panel of experts throughout the growing season and at harvest time.

The judges are looking at shape and uniformity, colour of skin and colour of flesh, yield, pest & disease resistance.

Four pots of each variety are to be planted at both RHS Rosemoor and RHS Wisley.  In total, 30 different varieties are being trialled. 

The trials at both Wisley and Rosemoor are open to be viewed by the public.  It's great to see such a wide range of potatoes being assessed side by side, helping gardeners identify the varieties best suited to their needs.

Not all varieties will gain an AGM award

While we're proud of our AGM-winning varieties, it's worth remembering that not every excellent potato receives an award. Many of the heritage and specialist varieties we offer were bred long before modern trial criteria existed and are grown for their unique flavours, history, character and appearance. Some may produce less uniform crops or vary more in size and shape, but what they lack in consistency they often make up for in taste and interest, making them favourites among gardeners and potato enthusiasts alike.

Additionally, all varieties that are being trialled here are fabulous (we know as we grow most of them!)  The criteria for this trial is to ascertain how well they do in pots.  They have other trials in other years, read about their maincrop trials here. 

If you think other varieties should be included for future trials or have any comments about this award, please contact RHS directly.
