The concept for this year's mini-tree was one by Margee Rader in my book, Succulent Container Gardens. The glass jar lid looks almost like ice. However, any container can work including a flowerpot. A small, shallow container makes the cutting look proportionally large and treelike. Unlike their spaced-out counterparts, tight-packed arrangements are considered to have a more rounded, finished look since the pot is already brimming with flowers. Remember that succulents should look like they are part of an underwater flora or fauna living in a coral reef. Succulents love fresh air and breezes.
