Bold and cheerful, Rudbeckia ‘Sunburst Radiant’ is a striking perennial prized for its vivid, rich blooms that brighten gardens from mid-summer to early autumn. Each daisy-like flower showcases lush chocolate red petals surrounding a rich, dark brown centre, creating a dynamic contrast that draws pollinators like bees and butterflies. Ideal for sunny borders, mixed flower beds, and wildlife gardens, this variety thrives in well-drained, moderately fertile soil and can tolerate drought once established. With a mature height of 40-60cm, ‘Sunburst Radiant’ adds vertical interest and pairs beautifully with ornamental grasses, Echinacea, and other late-season perennials. Its sturdy, upright stems make it an excellent choice for cut flowers, bringing a burst of colour indoors. Deadheading spent blooms prolongs flowering while helping to maintain a tidy appearance. Low-maintenance and resistant to most pests and diseases, Rudbeckia ‘Sunburst Radiant’ is a reliable, long-lasting option for gardeners seeking a bold, cheerful display that endures seasonal challenges.
