Sneezeweeds (Helenium)

Sneezeweeds

Sneezeweeds have composite daisy-like flowers that are attractive to pollinators. They are familiar wildflowers in many habitats throughout their range. The name "Sneezeweeds" comes from the traditional use of dried, crushed flowers to induce sneezing for ritual purposes; however, the flowering itself seldomly causes pollen allergies.

Water: Sneezeweeds thrives in moist environments, preferring consistent hydration. It is moderately drought-tolerant but benefits from weekly watering. Seasonal rainfall patterns should influence its watering schedule to accommodate natural precipitation.

Propagation: Propagation of sneezeweeds includes seed sowing, cuttings, and division, requiring proper light, temperature, and well-draining soil. Division is best done in spring or fall. Avoid overly wet conditions. Sow seeds after frost; use rooting hormone for cuttings; and split clumps every 2-3 years.
