By Spring 2015 there were over 250 different Mentha cultivars in this Heritage collection.
The collection has been accumulated mostly from UK sources with the occasional cultivar having been found at locations inside Europe and the US. They have been acquired from horticulturist, specialist growers, garden centres, different gardens, ditches, wastelands and forest floors. They have been brought to me by visitors. And some of them have just cropped up in the shingle around my greenhouse The classification of this genus needs some attention, with the situation becoming increasingly complicated due to the commercial proliferation of new varieties and the freedom with which this species complex can cross-pollinate to produce viable hybrids.
I am now in the process of adding data to this site so it will be constantly updated over the next few months. Click on this link to see the full list of cultivars:
The Chilgrove Mints 
Hello, I’m from the Czech Republic and I’m also collecting mint.Please please bugs in the text but translate it to Google Translate.You come from UK? And would it be possible to send certain species by mail? At the moment, I have some 130 species of Mata in my collection (after the winter a couple of them did not survive).
Thank you
Hi Thomas,
Thank you for your interest in the Mentha collection. I am just an amateur collector so I do not produce extra plants and I do not usually post mints … I just give cuttings of them away to visitors. BUT there are several suppliers who do provide mail order. The biggest supplier is Penborn Goat Farm:

The owner, Pete Oldfield, is also a Mentha Collection Holder. His collection is very comprehensive. But I don’t know whether he posts to Europe.
What mint was it you were wanting? I’m sure he’ll have it. He makes a point of collecting all listed varieties. I’m more of a researcher, finding new varieties from the wild and developing new cultivars such as 163: M. spicata microfolia Leonis, which I selected to be a small-leaved variety. I gave some to Pete Oldfield.
Do let me know if you have any mint queries. And I’d love to see images of Czech mints. The closest I have seen was a variety called “Betty’s Slovakian” which seems to have disappeared from the catalogues.
Beste, Jean
Hello, please look at your email. Thank you Thomas
Hi I’m in Iceland at the moment. Will catch up when I return home. Bestie Jean
Hello, and some mint Icelandic? 🙂
Thomas
Hello, you have a complete list of all kinds of mint ??

Hi there,
my name is Sam and I am a researcher in Food Chemistry at the Edmund Mach Foundation in Trento, Italy.
I recently started a project on Mentha looking at the phytochemical profile of the plant. At the moment I am collecting the samples.
Would it be possible for you to collaborate with my institute by providing us with some Mentha germoplasms.
Thanks for your consideration.
Best Wishes,
Very happy to do that but what form would you like them to take … rhizomes, mature flower heads with possible seeds, stems with adventitious roots? They are not that good at the moment since it’s approaching the end of their season, earlier this year due to the dry summer. Are you concentrating on one speces, eg spicata or a selection across the genus. I have a small number of cultivars included, which I call my Italian mints, that defy classification. But they do not smell as fine as the spicatas or piperitas. I think they have a lot of aquatica in them. Let me know what you need. Best, Jean
Hello John,
Thanks for your prompt reply.
At the moment I have various species of Italian Mentha, e.g., requienii, suaveolens spp insularis, puleggium, and acquatica, but I am looking for other species as well. I need stems and leaves.
I am not focusing on the aroma of Mentha, but on some molecule have sweetening activity.
I understand this might not be the right period of the year, but it would be useful to me having some samples anyway, in order to perform preliminary analyses.
Thanks a lot for your consideration.
Let me have a mailing address and I’ll send you rhizomatous samples from two mints I collected in Italy. I’d be interested to know what you think they are. Leaves and above-ground stems are dying back at the moment. If these samples do not work we can try again in the springtime. Beste, Jean
