The red stems and blue flowers Midnight Dutchess Lacecap Hydrangea standout against white flowering perennial Astilbe.
What Houzzers are commenting on:
Flower combination along the south front yard short fence. Bridal Veil Astilbe and Lace cap Hydrangea. Both do well part sun/shade. I don't think it would make the area over busy but w/l your and your architect's opinion. 3 Astilbe and 2 hydrangea can grow to about 4 feet long the fence line.
