Drinking my tenth cup of coffee at 7 am, perched on the back porch steps, I'm anticipating another season of thwacking at the vines that have been strangling my garden for 30-odd, emphasis on the odd. I wrote the following several years ago and haven't had a better thought on the subject since:
Apart from the pathetic wisteria that gallops across the roof of the garage, the trumpet vine was the dumbest idea for my bathtub sized garden.
I first saw it many years ago, in Rehoboth Beach, announcing a restaurant entrance.
What an exotic transition I thought it announced from the hurly burly scene on the street where the halter-topped and coconut scented beach-goers wandered, dripping pizza and ice cream. Being as this was so early on in my gardening, um, career, I had no idea what it was except that it looked fabulously tropical and was heavy with flowers and my id cried out I WANT ONE.
Amazingly, it took years to find in a garden center. I don't know if this was because the trumpet vine was once uncommon or if it had been in garden centers all along but I hadn't noticed -- or if the wise purveyors of plants knew that this was a rascal, a mad weed capable of smothering everything in its path -- dueling only with the mighty wisteria for dominance; King Kong vs. Godzilla vs. the tulip.
It is clearly called invasive in every article I've read after I bought and planted it.
