Dogtooth Sneezeweed (Helenium autumnale) is a gorgeous addition to the garden that begins to put on its show when other perennials are fading. This upright, clump-forming perennial has branching stems with lance-shaped, dark-green leaves that are topped with cheerful, daisy-like flowers from late summer to early fall. For allergy sufferers, don't let its name fool you. Its name comes from its history in the making of snuff, not for being a common allergen. Use this plant to add late-season interest to perennial beds and borders (especially when planted in larger drifts among ornamental grasses), cottage gardens, prairie and meadow plantings, rain gardens, or cut flower beds. Sneezeweed is an adaptable plant and tolerates a wide range of soil conditions, even surviving periods of consistently wet soil or temporary flooding. It is somewhat tolerant of urban pollution.
