Small space trees are an outstanding option for those in urban areas or with limited garden space. Varying the height and creating layers adds interest to an already attractive garden. Some offer gorgeous flowers while others stun with their bold leaves and striking fall color. Small space trees are generally less than 20’ tall and wide with some only reaching 8’.It’s important to have a clear understanding of the space available in order to select the right plant. You can always prune to reduce size, but it’s best to start out with the right sized plant for your location and plan for its mature size.
