There were some lovely plants but I know that a lot of them are raised in greenhouse situations and do not fair well when planted in the garden.
We bought some plants from the Gardens' own stall - Doug got a couple of Clivias and I bought a Euthorbia cotinifolia. Not too sure about my choice after reading more about it but I liked the look of its bronze colouring.
We then had a look around the Gardens which are in an old dis-used quarry and run by volunteers.
