Mint - hardiness

I enjoy growing mint, and for the past few years have pot grown some of the common varieties
I have recently bought quite a few more unusual varieties.
These are also growing in pots on the patio.

The more common varieties are fully hardy. They always come up again in the pots every spring.
But am not sure about the more unusual varieties ?
Do they need some sort of protection over winter ??
Does anyone have any experience with them ??

 

I've grown many varieties over 40+ years and found all of them hardy.
Having had a quick Google too it also reports that all varieties are hardy throughout the UK.
The main reason for dying over winter is wet roots.

Thanks for that.

I went to a garden center that had 20+ varieties, so I got them all

 

You don't do thing by halves then
My favourites were applemint or spearmint for cooking and eau-de-Cologne mint just for the wonderful smell and it is what the perfume is made from.

 

They were £1.50 each.
So not all that expensive.

May not keep them all if I don't like the smell / taste.

 

Enjoy!!

I just had a vague recollection that different varieties of mint should not be grown close together, so I had a look at the RHS site which says -

Avoid planting different varieties of mint close together, whether in pots or the ground, as they can lose their individual scent and flavour.

These are doing well so far.
Have filled the bigger pots that I have planted them into

Am slowly working my way through them - some seem to make better tasting tea than others.
