I planted three varieties of sweet potato vine in the back garden this year.
One was rather puny and the bright green one outshone the other two and began to take over the garden wall. One day I noticed the puny vine had begun to climb the hill into the woods.
Have you seen areas where English ivy has grown unabated?
I have this fantasy that the sweet potato vine up in the woods is going to be gargantuan and take over the back hill. Of course, it will be too mannerly to interfere with our hundreds of daffodil bulbs. Other than the daffodils, look out!
