The Latin name for moss Roses is Portulaca, but our Mom said moss roses and she loved them. They are an annual and grow so well here because their needs are few when it comes to watering. I love them too. Today would have been our Mom's 96th birthday if I have calculated right. She was an interesting woman, with a ready laugh, loved a good story, researched anything unfamiliar to her, was a good dancer, gardener, and Democrat. We all loved her and miss her today.
