Helenium vernale, commonly known as Savanna sneezeweed or spring sneezeweed, is a perennial herb native to wet savannas, pine flatwoods, and moist open areas in the southeastern United States, ranging from Louisiana to the Carolinas. It typically grows up to 31.5 inches (80 cm) tall and is characterized by its winged stems and clusters of bright yellow flowers. Each plant can produce 1-3 hemispherical flower heads, which contain up to 800 yellow disc flowers surrounded by 13-30 yellow ray flowers. The blooming period occurs in the spring, and the flowers are quite showy, attracting various pollinators.

Savanna sneezeweed is valued for its vibrant yellow flowers that provide a splash of color in early spring gardens. It is often used in wildflower gardens, rain gardens, and as part of naturalistic plantings to enhance biodiversity. This species thrives in full sun to part shade and prefers moist to wet soils with good drainage. While it is not drought-tolerant, it can withstand temporary flooding, making it suitable for areas with fluctuating water levels. Gardeners should be aware that, although not aggressive, it can self-seed under optimal conditions. There are no major disease problems, but it can occasionally suffer from fungal issues in overly humid conditions.CC BY-SA 4.0
