I have loved cemeteries for a long time. My husband has gotten used to stopping at stray little cemeteries when we stumble on them, and the boys always ask to stop when we see one, so when we saw a road named "Burton Cemetery Road," we had to stop. It wasn't a particularly old cemetery, but it was lovely and well kept with interesting headstones. There were also a few owls there. I've rarely seen an owl, and the boys thought it was great.
When I started to learn more about Old Garden Roses, I read that many old roses have been found growing in cemeteries, especially in warmer states than I've ever lived in. There are even people who go around collecting specimens of old roses (see this site for "rose-rustling" etiquette).
We visit a number of old cemeteries every Memorial Day and I love to see all the flowers (although there is a preponderance of potted mums the last few years- they may be cheap, but it's getting a bit old), but my favorite thing to is see what has been planted in the cemetery. You have to go to the old ones to see anything, because more modern cemeteries are far too well-groomed to allow anything like a scraggly rose bush on their grounds. One cemetery has beautiful peonies planted next to my great-great-great grandparents tombstone and they are sometimes blooming at Memorial Day (usually they're not quite ready though).
I also liked the cemeteries in the Middle East. They are more distinctive than ours, and in many ways quite as peaceful. The City of the Dead, a huge cemetery in Cairo, has thousands of homeless people living in it since many of the tombs can easily house living people also. But my favorite tomb, really, a mausoleum, is Qayt Bay.
I've always said that I'd love to live in an old church next to a cemetery.
