When summer heat fades the early bloomers, these perennials take over — often flowering right up to frost. Less predictable than mums, they return year after year with minimal care.
Orchid-like walnut-sized blooms (white, mauve, yellow) on graceful stems. Zones 4–9, part to full shade (more shade south), moist humus-rich soil, tolerates wet. 'Miyazaki' (purple-speckled, arching), 'White Towers' (pure white).
Tall, shrubby, fragrant, 15-week bloom even in hot sun. Zones 4–9, full sun, drought tolerant. Great with daylily, salvia, dianthus, Japanese anemone, boltonia, orange coneflower, sedum.

Southwest-vivid yellow/burgundy/red midsummer to fall. Fertile well-drained soil preferred; tolerates poor dry soil once established. Deadhead for rebloom. 'Goblin' (dwarf, compact), 'Burgundy' (2–3 ft, deep red).
Jeffrey Gordon Smith Landscape Architecture
Lanky stems, semidouble pink/white flowers late season. Long-lived, fibrous-rooted. Mass in borders or mix with hostas/obedient plant. Prune post-bloom to limit reseeding/spread. 'Honorine Jobert', dwarf Pretty Lady series.
Shades Of Green Landscape Architecture
Near-indefatigable bloomer: lavender-blue, deep blue, white, pink from early summer to early fall. Deer resistant, tough. Containers or front-of-bed groups. Deadhead for longer bloom.
All-American favorite, profuse, easy. Naturalizes in cottage/meadow gardens. 'Goldsturm' = reliable, long-lasting. Pair with purple Frikart's aster or grasses for autumn glory.
Milieu Design
Indigo-blue spikes, late-season encore with deadheading. Butterflies/hummingbirds love it. Zones 4–9, full sun, drought tolerant. Mix with yellow flowers, purple sedums, lamb's ears.
Genevieve Schmidt
Snapdragon-like spikes (white/pink/magenta) stay pushed — but the plant spreads aggressively. Choose 'Miss Manners' or 'Pink Manners' for clumping behavior. Zones 3–9, sun to light shade.
Fullmer's Landscaping, Inc
Workhorse in tough spots: wet soil, dry shade, dense shade. Fragrant soft yellow clusters April–mid-October on ferny green leaves. Zones 4–9, part sun/shade.
Carefree summer-to-autumn color. 'Monch' = lavender-blue July–October. Mulch in winter in cold zones. Zones 5–8, full sun, dry to medium soil (rots if wet over winter).
