A few weeks ago I was working in our vegetable garden, pulling weeds and watering. A bright yellow flower and some green tendrils caught my eye, unexpected in a corner where red trumpet flowers reign. Taking a closer look I noticed a long, slender vine cascading over the fence separating our garden from our neighbor’s. Besides the cup-shaped blossom, large scalloped-edge leaves gave hints for classification. I wondered about the mystery vine. The only thing certain was its origin: the adjacent side yard. My curiosity could easily have been satisfied had I simply walked next door, rung the doorbell and asked a single question, but I enjoy puzzles, so instead, I decided to wait for more clues.
