These short-lived perennials or biennials are charming plants, and are worth their weight in gold in the cottage border. After flowering, the attractive foliage holds the space well.

This garden phlox has striking, bicolor lavender-and-pink flowers beginning in early summer and displays a pleasing compact form. Its slightly waxy leaves hold powdery mildew at bay, and the plant doesn't even flinch in heat, humidity, or drought. 'John Fanick' grows to 3 feet tall and 2 feet wide.

This stunning herbaceous woodland peony has upright red-mottled stems and dark green leaves that are elliptic or lance-shaped with rough margins. It bears usually solitary, single creamy white to pale pink blossoms that are cup-shaped and elegant. The blooms measure 3 to 4 inches across and have pale yellow stamens. Like all peonies, the flowers are with us for too short a time. They are followed by beautiful seedpods.

This woody-stemmed perennial produces sticky spikes of deep violet or, rarely, white to pink flowers. It blooms from early summer to autumn; reblooming is most reliable if spent flowers are deadheaded promptly. It has wrinkled leaves and forms an upright clump 3 feet tall by 1 foot wide. This salvia is most noted for its many hybirds with S. nemerosa.
