An important plant for butterflies and other pollinators, Butterfly Milkweed is a host plant for Monarch Butterflies. ‘Caramia’ Salvia works well as an edger for perennial beds, walkways, or anywhere a neat and tidy look is wanted. ‘American Gold Rush’ Black Eyed Susan and ‘Sombrero Baja Burgundy’ have won the top honors from All American Selections for their beautiful flowers and exceptional habit. Their outstanding blooming power almost rivals many annuals. Use them where you don’t want to replant year after year.

    Although many of these plants are drought tolerant, for best flowering give good soakings during dry spells. Most of these plants will continue to bloom without deadheading, but for maximum blooming clip off spent blossoms before the plants start to go to seed. You’ll want all the plants’ energy to go into making more flowers.
