Small flowering trees are gaining in popularity for several reasons. First, small 3 to 6 m (10 to 20 ft) trees fit modern landscapes where yards are small. Secondly, there is a growing and somewhat justified fear of urban trees that get huge with time. In an age of hurricanes, tornadoes, wild weather and predictions by climatologists of more of the same, it is only reasonable to embrace a little fear of large trees. Part of climate change ― is violence. Crushed homes, vehicles, and power lines are becoming nightly fare on our national news. Small flowering trees suddenly look better. Thirdly, there is an ever-expanding list of new varieties entering the market with attributes of tree form, leaf shape and color, and flower size and color. Finally, five to ten gallon container-grown plants mesh well with the displays at the mass markets, independent nurseries, and landscape companies.
