The following is from their website, which I highly recommend, especially to my gardening friends. http://www.rbge.org.uk
“The Royal Botanic Garden Edinburgh (RBGE) was founded in the 17th century as a physic garden. Now it extends over four Gardens boasting a rich living collection of plants, and is a world-renowned centre for plant science and education.
"exploring and explaining the world of plants for a better future"
“That's our mission. Without plants, there would be no life on earth. RBGE has been growing and studying plants for over 330 years, and so is perfectly placed to help document and conserve the world's diversity of plantlife.”
