Last chance to grow.......?

Just received an email from Plants of Distinction that's a bit worrying:-

[b]New rules coming into place at the end of the year[/b]

will mean that we are unable to continue offering the wide selection of Heirloom Tomatoes that many of you have enjoyed growing over the years.

Our new catalogue will be available in a few weeks and you will see a big change in the Tomato section. We do have lots of lovely new varieties to tempt you, however most of the heritage varieties we have all come to love will no longer be included and so whilst we are still able, we wanted to give you a chance to grow these favourites for one last time.

Familiar names such as Black from Tula, Caspian Pink, Halladay’s Mortgage Lifter, Hill Billy Potato Leaf, Japanese Trifle Black, Lemon Tree, and Russian Black are just a few of the varieties disappearing from the UK for good.

I presume this is something to do with Brexit or ?paying to register seed varieties?

Whatever the cause, its all the more reason for us to save heritage/open pollinated seeds before they disappear for good.
