Dwarf Japanese maple trees maintain a deep red color most of the year, and they look great in containers. The Dwarf Japanese maple is small in stature with profuse branching and vivid color. This tree requires little maintenance and medium water, and it does well in full to partial sun. The Dwarf maple is perfect for a patio or small yard.
"Don’t think you can plant trees in containers? Think again. These birch trees are placed in large containers, and because the root ball is kept from growing outward, the whole tree remains smaller and more manageable."
