Top Flowers for Fall Color

Obedient Plant

Know how the obedient plant Physostegia virginiana got its name? If you point an individual flower in one direction, it remains there. That's all that's obedient about the plant, though. Give it rich, moist soil, and it spreads aggressively.

Still, its 10-inch spikes of pink or white blossoms make good cut flowers and add long-lasting color to the fall border. If it spreads too much, dig up what you don't want, and share it with someone you like -- or even someone you don't.
