Native of the upper Mississippi River Embayment; early cultivated elsewhere and escaped. | |
| Abundance | Uncommon to infrequent in the Piedmont, rare in the Mountains, Sandhills, and Coastal Plain. | |
| Habitat | Roadsides, along creeks and rivers, disturbed woodlands, escaped to edge of parking lot, moist pineland (Bladen Co.). | |
| Phenology | Flowering May-July; fruiting July-September. | |
| Identification | This exotic tree, familiar to most people in yards and gardens, is much like C. bignonioides, which see, but the leaves taper gradually to the tip with sides that are relatively straight (or even slightly bowed outward, but not distinctly curved inward as in C. bignonioides). Some leaves lack a drip-tip. Its large flowers are more boldly marked, as well. | |
