False Sunflower 'Prairie Sunset' is a robust, clump-forming perennial native to eastern and central North America that brings summer-long golden blooms to any sunny garden. Growing 3 to 5 feet tall with a spread of 2 to 3 feet, this hardy variety thrives in zones 3 through 9 and tolerates conditions that challenge fussier plants: drought, clay soil, poor soil, and shallow rocky ground. Its daisy-like flowers, measuring 2 to 3 inches across with bright yellow-orange rays surrounding brownish-yellow centers, bloom continuously from June through September and draw butterflies and birds throughout the season. With minimal maintenance and genuine drought tolerance once established, it earns its place in low-water gardens and naturalized borders.

The 'Prairie Sunset' variety handles brutal growing conditions with grace, thriving in clay soils and drought that would defeat many perennials. Butterflies and birds flock to the flowers throughout a long summer season, and the stiff stems hold the blooms upright without fussy staking in most situations. Low maintenance and genuinely easy to grow, it rewards neglect rather than punishing it, making it one of those rare plants that actually improves a garden without demanding constant attention.
False Sunflower serves as a pollinator magnet in sunny borders and native plant gardens, where its extended bloom season from June through September provides reliable food for butterflies and nesting material for birds. The cut flowers last well in arrangements, bringing that bright, cheerful sunflower character indoors without the height or single-stem drama of true sunflowers. It anchors the back of mixed perennial beds or naturalizes across slopes and disturbed areas where erosion control matters as much as ornamental appeal.

Start seeds indoors 6 to 8 weeks before the last spring frost in flats or trays. Germinate at 60 to 75°F; seeds typically emerge within 10 to 14 days. Keep soil consistently moist but not waterlogged during germination.
Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days after the last frost date. Transplant into the garden when plants are 3 to 4 inches tall and soil has warmed to at least 50°F. Space plants 24 to 36 inches apart to allow for mature width.
Direct sow seeds into the garden after the last spring frost once soil has warmed. Press seeds onto the soil surface or cover lightly, as light exposure aids germination. Keep soil consistently moist until seedlings are established.
Cut back stems by one-third to one-half in late May to control height and encourage a fuller, bushier form; this prevents excessive legginess and reduces or eliminates the need for staking later in the season. Deadhead spent flowers throughout the blooming period to extend the display into September and redirect energy toward new buds rather than seed production. In late fall or early spring, remove any winter-damaged or dead stems at ground level.
