The two tall 'palm tree' looking plants are succulents. I'm not sure what they are called. I found them at a flea market garden shop. The owner did not want to sell them to me when he learned what I was going to use them for as he said they grow very big. I was not concerned about the size as I knew I would eventually take them out of her fairy garden before she killed them.
To the left of the "palm" is a miniature rose and some other succulents. The "grass" is scottish moss. I'll be putting her fairy garden back together soon (but keep it at my house this time). The rose died as did the moss. The rest of the plants are alive...barely...but I will bring them back to my place and will nurse them back to health.
