Is it more difficult to attract hummingbirds to an urban setting? I have grown the following for years: Butterfly bush, lantana, columbine, clematis, fuscia, impatiens, Rose of Sharon, honeysuckle, and have recently added pentas and delphinium. I also have plenty of daylilies, roses, gernium, petunias, gaura, hosta, hydrangeas, liatris, bidens, celosia, etc., although I don't think they necessarily attract the little guys. What's a girl got to do? I've had feeders but got tired of filling them on a daily basis when I had no visitors. I'm about to give it another try however. I am in the middle of a large city, is that my problem? Thanks.
