Helenium autumnale


Sneezeweed is a perennial wildflower that can grow up to 1.5 m in height. The leaves are dark green colored, alternately arranged, lance shaped, and have entire or slightly toothed margins. They also sometimes have small, narrow leaves on the flowering stems. The flowers are showy, bright yellow colored, have distinctive lobed petals, a large dome-like center, and bloom between August and October. The flowers are beneficial to pollinator species, like bees and butterflies.

Planting conditions

Sneezeweed grows best in moist to wet conditions with full sun exposure. It prefers poorly drained, organically rich loam or humus soil types. It is tolerant to deer, clay soil, and seasonally flooded areas. This wildflower can be naturally found in wet meadows, moist ditches, around marshes, and along streams, ponds, or lake shorelines.
