I have an old poster (somewhere) of the San Francisco Conservatory, the botanical kind, from what would appear around 1900. On the grounds in front is a very large, maybe 20 foot diameter sundial, with plants all around and the gnomon covered in ivy. Very inspiring. I post the picture someday when/if I find it. sasch stephens
