HELENIUM autumnale (Autumn Sneezeweed) is a perennial flowering plant that belongs to the Asteraceae family.

Autumn Sneezeweed is a tall and upright perennial that typically grows to a height of 3 to 5 feet (90 to 150 cm) and spreads about 2 to 3 feet (60 to 90 cm) wide. It has sturdy stems and lance-shaped leaves that are deep green in color. The plant produces clusters of daisy-like flowers at the top of the stems.

The flowers of Helenium autumnale are the highlight of this plant. They are typically yellow to golden-yellow, although some cultivars may have shades of orange or red. The flowers have prominent central discs and ray florets surrounding them. The petals are often reflexed, giving the flowers a vibrant and eye-catching appearance.

Autumn Sneezeweed typically blooms from late summer to early fall, hence the common name. The flowering period can vary depending on the specific growing conditions and climate. The flowers are long-lasting and provide a burst of color in the garden during the late summer season. The vibrant flowers of Autumn Sneezeweed are attractive to butterflies, bees, and other pollinators. They provide nectar and pollen, making the plant valuable for supporting pollination and encouraging biodiversity in the garden. Birds may also be attracted to the seeds produced by the plant.

Helenium autumnale thrives in full sun to partial shade. It prefers well-drained soil and can tolerate a range of soil types, including loamy or clay soils. It is relatively adaptable but performs best in fertile soil that retains moisture. Autumn Sneezeweed requires regular watering, especially during dry periods, to maintain its vigor.

Helenium autumnale is generally low-maintenance. Deadheading spent flowers can help promote prolonged blooming and prevent self-seeding if desired. However, allowing some seed heads to mature can support the natural reseeding of the plant and create a self-sustaining population. The plant may benefit from dividing every few years to maintain its vigor and prevent overcrowding.

Autumn Sneezeweed (Helenium autumnale) is a striking perennial plant that adds a splash of late-season color to gardens and landscapes. With its vibrant flowers and ability to attract pollinators, it is a valuable addition to wildlife gardens and late summer planting schemes. Its tall and robust growth habit makes it suitable for the back of borders or as a focal point in the garden.
