Answer: Trumpet vine flowers occur on new growth (as opposed to flowering on old wood). I would suspect that the plants are busy building up reserves in their root systems to enable flowering. Also, Lockport is the northern edge of their range and they may nothave a long enough growing season to put out flowers, especially if they dieback to the ground each year. Pamper them through the winter, especially before you get your famous snows, and they should flower as the plant ages and matures..
