This was not an original idea but I thought it was cute. I "planted" an overturned flower pot in the pan a couple weeks ago and seeded it with grass. After the grass was up I added the stone, three crosses made from sticks, and flowers. It was fun to put together. My grass grew faster than I expected and I had to "mow" it with a scissors when it hid the crosses.
I put it on the table for a centerpiece at our Easter dinner on Saturday and got a little more mileage out of it by taking it to church this morning.
