The Story
Plant Bio
Helenium autumnale is an upright, clump-forming perennial with stiff, winged stems. It features daisy-like flowers with distinctive wedge-shaped, drooping ray florets surrounding a prominent, dome-like central disk. Native to North American wetlands and moist prairies, it is an excellent choice for rain gardens and naturalized areas. The common name 'sneezeweed' comes from the historical use of its dried leaves to make a snuff that induced sneezing.

Planting
How to Grow
- Choose a sunny location with well-draining soil to plant Helenium hydranchiton.
- Tuck seeds or seedlings into the soil, spacing them about 18-24 inches apart for airflow.
- Water thoroughly after planting to settle the soil around roots, maintaining consistent moisture.
- Mulch around plants to retain soil moisture and suppress weeds, especially in dry seasons.
- Fertilize with a balanced, slow-release fertilizer in early spring to promote healthy growth.
- Prune back dead or damaged stems in late fall or early spring to encourage bushier growth.
