A couple years ago I decided to list a flowering vine as a Weed of the Week in the Tribune Chronicle summer feature “How Does Your Garden Grow.” While I purposely bought this vine to put in my own garden, without thinking of its history or growth habit, it soon became apparent that it could be a potential problem in my garden. Who hasn’t brought plants into the garden for one reason or another, only to have regrets later on? Although, I have to admit that I still harbor no regrets, for myself at least. My husband, however, does have regrets, and lots of them. Let me explain. Several years ago I was taking an aerobic class at a gym in my hometown and I noticed where I parked my car near a fence a lovely vine was growing with remarkable tubular orange flowers. Those in the know have likely guessed that I’m writing about — Campsis radicans, or trumpet vine. At that time, however, I didn’t know what it was.
