There have been a
number of books on mints published during the last couple of decade, but I
have only been able to get one through WHSmith online. (Smiths did list many others
as available through their website, but only one materialised.) Unfortunately
this book from the USA is very expensive, without the type of content I think
the UK mint gardener would find helpful in collecting and growing their
plants. So the rest will only be available second hand. Details of these will
appear on this page later in the year.
