What is Helenium ‘Luc’ (Sneezeweed)?

Helenium ‘Luc’ is a perennial plant that belongs to the family Asteraceae. This vibrant flowering plant is native to North America and is known for its daisy-like brightly colored blooms that adorn the garden from midsummer through fall. The common name “sneezeweed” can be misleading as the plant does not actually induce sneezing. The name is derived from the historical use of its dried leaves and flowers in making snuff, which would cause sneezing when inhaled.

This plant typically reaches a height of 3 to 6 feet, depending on the variety, and forms clumps of upright stems with lance-shaped leaves. The most striking feature of Helenium ‘Luc’ is its abundance of colorful flowers, often in shades of red, orange, and yellow, that add a pop of color to the landscape.
