Black and white, with contrast pushed high, works well to bring out the interesting textures and patterns here. Those two daffs provide the detail that makes this work for me.
I am making two passes on this Challenge. I will vote on your photo then return later(before voting is over) to comment on what I like and dislike about your shot. You can take the comments however you wish and I will try not to be mean. Just don't take it the wrong way.

One where the border works. I also love the shadows.
Th elight is a bit harsh and the subject a bit boring. Try a different angle, lie down on the ground, stand on the gravestone and shoot down. The featureless (near) stones and the expanse of boring wall just make this a bland shot...sorry.
