I can't make up my mind what I want, my creativity is tapped dry. Want something at least 3' tall, no higher than 6' absolute tops. North-facing bed, gets morning sun year-round, sun in afternoon in summer. Good soil - neither too dry nor too moist, moisture-retentive and drains well.

To the one side of the empty area are "Annabelle" hydrangea, "Blue Shadow" fothergilla, and a dwarf globe blue spruce. To the other side of the empty area is a young paperbark maple with "Sykes Dwarf" oakleaf hydrangea, "Yuki Snowflake" deutzia, another dwarf globe blue spruce, and wrapping around the corner behind the tree into the side bed are winterberry hollies. Have some perennials mixed in there as well for accent, but this is primarily a shrub border for the foundation. I'm trying to avoid too rounded of a shape because of the swath of fothergillas and Annabelles - I need a contrast, and I need something visually "heavy" because another part of the bed in front of my large front door has a grouping of Zebra gass and a mature tree peony -- so basically now the bed looks visually lopsided with the heft skewed heavily towards the other side (and it will take quite a while for the paperbark maple to mature for visual balance). I don't want to add any more ornamental grass because the zebra grass highlights the door beautifully, and I'd like to keep that as a focal point.

I'd like to fit in a grouping of three shrubs, but can get away with two if they're "wow"-type shrubs with some artful re-arranging.

My choices at this point are "Henry's Garnet" itea, "Weston's Innocence" deciduous azalea, and "Lemony Lace" elderberry. Which one do you think might look the best? I'm open to other ideas, too.
