Synonym(s): Koelreuteria apiculata
Family: Sapindaceae (Soapberry Family)
Duration and Habit: Perennial Tree
Goldenraintree grows 30 to 40 feet tall with an equal spread, in a broad, somewhat irregular globeshape. Some trees appear vase-shaped. Although it has a reputation for being weak wooded, it is rarely attacked by pests and grows in a wide range of soils, including high pH soils. The tree grows moderately and bears large panicles of bright yellow flowers when few other trees bloom.The seed pods look like brown chinese lanterns and are held on the tree well into the fall.
Native Lookalikes: Currently no information available here yet, or there are no native Texas species that could be confused with Golden rain tree.
Ecological Threat: Escapes from cultivation and naturalize in Texas, Louisiana, Alabama, and Florida. It is a fast grower and has great seed viability in warmer climates, Koelreuteria has the ability to crowd out desired native species.
Biology & Spread: Reproduction occurs via seed that can germinate quickly, within a period of 6 to 8 days. Water may contribute to the spread of the seeds, although this has not yet been proven. Birds may also play a factor in the dispersal of the seed.
History: Introduced from China as an ornamental tree.
U.S. Habitat: Warm moist areas of Texas.
U.S. Nativity: Introduced to U.S.
Native Origin: China
U.S. Present: AL, AR, CA, DE, FL, GA, ID, IL, IN, KS, KY, LA, MA, MD, MO, NC, NJ, NY, OH, PA, TN, TX, UT, VA, WV
Distribution in Texas: Prominent in Gulf Coast of Texas, along with other areas where it has escaped cultivation.
