A tree is a woody plant with a single trunk and a distinct canopy, usually growing more than 15 ft (4.6 m) tall. Trees can be broad-leaved or needle-leaved and evergreen or deciduous. Broad-leaved deciduous trees create shade in the summer and let the sun through in the winter. Evergreens make the best screens and provide year-round color. Before placing trees in the landscape, consider their ultimate size. It’s sad to have to remove a healthy, tall and handsome tree because it was planted too close to the house.
