Shrubs for a hedge
I could use some recommendations for a hedge for the front of our house, bordering the public sidewalk. I had spirea, and it was nice, but I decided I wanted a change. One thing I'm looking for feedback on is if anyone has done a 2-tiered hedge, with one type of bush in the front, staggered, and then another tier filling in the blanks from the other one. I've been driving around trying to find something "in the wild" that I like, but am not having much luck. I am thinking of doing either all barberry or a row of barberry and something flowering, like shrub roses. I like barberry because it has some color in both summer and winter, grows fast, and is around the height I'm looking for. I was actually thinking of something up to 5 feet tall, so if anybody has any ideas for shrubs they think would look nice in a hedge that get to up to 5 feet tall, I would be thrilled to hear about it! Thanks for your help.
