|With more than 300 species of annuals, biennials and perennials, these are one of the most popular garden perennials. They range from diminutive, mounding rock garden plants to 6-foot spikes of color. Their showy bell-shaped flowers are commonly found in clear whites, cool blues, rich violets and lavenders, and occasionally soft pink. Use short mounding species in rock gardens and containers and the taller species in perennial borders and for cut flowers. Many species thrive in full sun or partial shade, but most need partial shade in hot-season climates. Pest problems are rare. Mulch against summer heat. Remove faded flowers to prolong bloom. Water during growing/blooming season.
Although invasive, its masses of lavender-blue flower clusters in early summer makes this a favorite. Cut back old flower spikes to encourage new blossoms.
