Corporate supporters


Our Corporate supporters play a vital role in helping us save the diversity of cultivated plants in the UK and Ireland from quietly vanishing forever.

As a Corporate supporter you will help us:

  • extend the National Plant Collection® scheme, which conserves amazing living libraries of plants
  • continue our work in identifying plants at a high risk of extinction
  • sustain a network of passionate local volunteers that offer a range of horticultural activities
  • promote our Plant Guardian® scheme, to enable individuals to care for rare plants and protect them for future generations
  • support our free annual Plant Exchange to increase the availability of hard-to-find plants
  • encourage horticultural skills and knowledge-sharing to grow and propagate our unique garden plants

What we can offer you

Working with Plant Heritage, the world's leading garden plant conservation and membership charity, demonstrates your commitment to plant conservation, which can be a valuable part of your corporate social responsibility.

As a Corporate supporter your logo will be on our website, and you can use the Plant Heritage logo on your website. You will have a welcome message in our e-newsletters, with advertising opportunities in The Journal, our twice yearly magazine, and the annual National Plant Collections Directory.

There are sponsorship opportunities at a national level, with celebrities such as our President Alan Titchmarsh, and through our displays at national gardening shows.
