Depending upon which region of the country you're in, the name "white cedar" is a common name that denotes several types of trees. Known for their towering heights and picturesque foliages, each type of white cedar tree has a distinguishing characteristic that defines the word "white" in its common name.
A perennial member of the Bignoniaceae or trumpet-creeper family, white cedar (Tabebuia heterophylla) is native to Florida, Puerto Rico and the Virgin Islands, according to the United States Department of Agriculture. The tree has a rapid growth rate and actively grows from spring through fall, reaching a maximum mature height of over 60 feet tall.
The tree's white trumpet-shaped flowers bloom in spring, giving the tree its characteristic white appearance. The tree then produces its fruit and seeds, which form from spring through summer. White cedar thrives in warm climates and cannot tolerate the frost of northern United States regions. It thrives in full sun and moist soil.
