There are a variety of trees that provide yellow blooms. Many trees produce bright yellow flowers in spring or summer. Some species bloom earlier, accenting the winter landscape with the first signs of spring. Wherever you may garden, there is a tree with yellow flowers for you.
Golden raintree (koelreuteria paniculata) is named in honour of Joseph G Koelreuter, a botanist from Germany who studied the pollination system of flowers. It grows quickly and produces seeds in abundance, with homeowners incorporating the tree into landscapes for its ornamental attributes. Golden raintree is versatile in different soils, has a habit of spreading and provides cheerful yellow panicles in summer. Blooms last for about two weeks.
Carnelian cherry dogwood
Carnelian 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 4.5 to 7.5 m (15 to 25 feet) tall with a spread that reaches about 5.5 m (18 feet.) It does well in a partially shaded site with well-drained soil. In autumn, foliage turns red for an attractive display.
Golden medallion tree
When provided with full sun and a well-drained soil, the golden medallion tree (cassia leptophylla) rewards with clusters of gold flowers in summer. This tree is a member of the bean family and produces long bean pods after blooming. The 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. Prune young trees for a pleasing and symmetrical canopy shape.
The flowers of the tulip poplar (liriodendron tulipifera) have six petals that are yellow-green with an orange band and are pollinated by honey bees. Appearing in late spring to early summer, the flowers resemble tulips and measure five to eight cm (two to three inches) long. It is often difficult to spot the flowers because they are found at the top of the tree which grows to about 45 m (150 feet) tall.
