Hi Linda. When I lived in California, I had a little rock garden with tons of little small leaved succulents, like Hen and Chicks. I made a wreath one year and it was lovely.
I purchased a round wire cage-like wreath frame and lined it with moss, filled it up with a planting mix, then covered it with more moss on top of the soil.
Then I chose the smallest succulents and began planting them in the moss by punching a hole and sticking the roots of the plants in. It was really quite lovely. I hung it on my front porch. To water it, I had a spray bottle to gently mist it when it felt dry.
