I love sunflowers and I loved your story. I am forced to grow smaller sunflowers in pots as my garden is wild with rabbits and moles. I will not use anything lethal to rid my garden of the rabbits or moles, so nature takes its course and my sunflowers are eaten to the ground. I even have to put my morning glories in pots!
Here's hoping your driveway will be filled with beautiful sunflowers (and morning glories) and an abundance of birds. Most importantly, I hope the wall of sunflower beauty doubles as a shield against any unwanted sights and sounds.
herk, the trick is to let SO MANY sunflowers go to seed that the moles & other critters can't keep up. Of course, having a dog + several cats roaming around is THE most natural pesticide in the world, you know.
