Golden raintree (Koelreuteria paniculata) is named in honor of Joseph G. Koelreuter, a botanist from Germany who studied the pollination system of flowers. The Center for Invasive Species and Ecosystem Health lists the golden raintree as invasive due to its fast growth and abundant seed production. Still, homeowners incorporate the tree into landscapes for its ornamental attributes. Golden raintree is versatile in different soils, has a spreading habit and provides cheerful yellow panicles in summer. Blooms last for about two weeks.
Cornelian Cherry Dogwood
Cornelian cherry dogwood (Cornus mas) is a harbinger of spring, producing tufts of yellow flowers in late winter. Fleshy red or yellow fruit develop in summer and attract birds. This type of dogwood has a round canopy and grows to about 15 to 25 feet tall with a spread that reaches about 18 feet. It does well in a partially shaded site with well-drained soil. In fall, foliage turns red for an attractive display in autumn.
Golden Medallion Tree
When provided full sun and a well-drained soil, the golden medallion tree (Cassia leptophylla) rewards with clusters of gold flowers in summer. Golden medallion tree is a member of the bean family and produces long bean pods following bloom. Seeds are poisonous and flower pollen incites an allergic response in some individuals. Native to Brazil, this tree has minimal cold hardiness, suffering injury when temperatures dip just below the freezing mark. The University of Florida recommends pruning young trees for a pleasing and symmetrical canopy shape.
Native to the eastern U.S., the distribution of tulip poplar (Liriodendron tulipifera) extends from Florida to Vermont and west to Missouri. Flowers have six petals that are yellow-green with an orange band and are pollinated by honey bees. Appearing in late spring through early summer, the flowers resemble tulips and measure 2 to 3 inches long. It is often difficult to spot the flowers because they are found at the top of the tree which grows to about 150 feet tall.
