Forsythia, << fawr SIHTH ee uh, >> is a group of shrubs that produce abundant yellow flowers. They grow as high as 9 feet (2.7 meters) and have spreading, arched branches. People sometimes call forsythias golden bells because they have yellow flowers that look like tiny, golden bells. One to six flowers grow in clusters. Forsythias produce many blossoms, which open in early spring before the leaves appear. The leaves grow 3 to 5 inches (8 to 13 centimeters) long and are egg-shaped. They usually have jagged edges. Forsythias grow well in any garden soil and can withstand cold temperatures. Forsythias are named for the British botanist William Forsyth.
