Bee Balm - It grows over 6 feet tall, smells great, self seeds and attracts hummingbirds. Add a leaf or two to black tea for that distinctive Earl grey flavor. I love the pop of color and the fact that it attracts hummingbirds!
list of good perennials Riotous with high-summer color, this perennial border is built to last. After the delphiniums fade, purple salvias and strappy-leafed variegated irises keep the show going till fall.
