I have a bed that is roughly about 6' x 12' in full sun with a bit of afternoon shade where I currently have a butterfly bush that I am yanking out due to poor performance. I also have a lil' miss kim lilac in that same bed. I would like to plant my jackmanii clematis and have it trail up a trellis that I am installing on the wall. I recently bought a PeeGee hydrangea that I would also like to include in that bed. My question is wether I should plant the clematis at the very back edge of the bed and plant the PeeGee a bit to the right or plant the PeeGee at the back left corner and plant the clematis to the right. Or if I should plant the clematis directly behing the PeeGee so that the roots are covered and then train it to climb a bit off to the sides...
Also, What do you think of the combo of the Peegee, Jackmanii and lilac? Anything else you'd throw in? I have six ducks and two chickens that are constantly getting in that bed and have obliterated most of my perennials that I had planted in it so I am opting for bushes now.
Here is a picture of the bed last year so it doesn't contain the Lilac in it:
