When I visit the cemetery I see many bushes and flowers planted that come up every year. I always see a lot of peony bushes - probably because these are usually in bloom around Memorial Day.
I have also seen many Iris flowers and Hosta plants at the cemetery I go to. These come up and bloom every year on their own.
In addition to the flowers there are many decorative items such as bird houses and wind chimes. Every grave site has its own story to tell and the flowers and decorations really add a nice touch.
