I'm about to start my garden this year, & I love fragrant plants and/or flowers! What kind of plants or flowers give off a strong, but good smell? I'd like people to smell my beautiful flowers as they walk up my stoop, as well as viewing them!... So I need to know what flowers to use, & where to put them in my yard so they can be smelled/viewed, w/ out over powering them. Make sense?

Thanks so much!!!
