Helianthus - Happy Days
A compact powerhouse among perennial sunflowers, ‘Happy Days’ forms a lush mound of dark green foliage topped by large, double golden-yellow flowers with a distinctive anemone-style center. Blooming from midsummer well into fall, its vibrant blooms shimmer on sturdy purple-branched stems and attract butterflies, bees, and hummingbirds. Perfect for middle-border placement, containers, or cutting gardens, this hardy cultivar thrives in full sun and moist, well-drained soils. Winner of the RHS Award of Garden Merit, it’s deer-resistant and easy-care, yet silently self-seeds to brighten future seasons.
