These are hollow topiary balls rather than potted trees, and that changes what they are for. Each one measures 20 in across the outside with a 16-in inner opening, sized to drop over the rim of a flowerpot between 10 in and 14 in wide so an existing planter becomes a finished topiary without repotting anything. They also sit directly on the floor or rest in a vase. Four layers of leaves build the surface. Depth is the whole point of layering: a vibrant green hue on the outer layer with more beneath means no frame shows through when the ball is viewed from below or at an angle, and the result adds a genuine touch of freshness rather than reading as a wrapped foam sphere. The leaves are PE and non-smell, and they resist sun, water, and fading for lasting use both outdoors and indoors. No maintenance is required to keep them evergreen, with no watering, sunlight, pruning, or fertilizer at any point. Each ball ships as two halves. They join with interlocking connectors and are secured with clips and zip ties, so assembly is a breeze and requires no tools, and the two-half construction is also why the pieces pack down rather than arriving as bulky spheres. The pair weighs 7 lbs together. If a ball arrives slightly deformed from transport, the shape comes back by setting it in the sun or warming it briefly with a hair dryer. The set is ideal for decorating a home, restaurant, wedding, front porch, balcony, or patio.
