The trumpet creeper, which is 

 native as far north as middle Illinois, is one of the most vig- 

 orous and tropical-appearing of hardy climbers. Its flowers 

 are among the most brilliant and largest of those borne by 

 such plants and, like most other American flowers with 

 large red tubular flowers containing a great deal of nectar, 

 are pollinated by humming birds whose visits afford another 

 reason for planting such vines as this and the trumpet 

 honeysuckle.
