Since I put this list together 7 years ago but I have now started to favour Kings Seeds (Suffolk Herbs) for my vegetables. I also get many more seeds from clubs and organisations rather than merchants.
My Regular Suppliers
Thompson-Morgan have 2206 different packets of seeds. Their catalogue is one of the most colourful and once on their list you get regular offers. They are a good partner to Gardeners Tips and if you buy via our link we get a small commission that helps with our costs – Searchable T&M site.
Wallis Seeds have a new web site and are based in Chelmsford Essex . I like buying by weight for some varieties that I can scatter willy-nilly so 15 gms of Calendula ‘Pacific Beauty’ and ‘Art Shades’ are on the way .
Chiltern Seeds of Ulverston Cumbria www.chilternseeds.co.uk have a 220 page densely packed catalogue. They are good for providing Latin names and flowery comments on each variety.
