Helen's Flower (Sneezeweed)
Helenium autumnale
Family Asteraceae

Helen's flower ends the season in fireworks — warm daisies in gold, rust, mahogany, and flame, stacked on 3-5 ft stems just as the border starts thinking about quitting. And clear its name: 'sneezeweed' isn't a hay-fever plant; that crime belongs to ragweed blooming nearby.
The last bees and butterflies of the year work it hard, which makes it quietly important as well as gorgeous. A moist-meadow native, it loves damp borders and rain-garden edges, weaves beautifully through grasses and asters, and cuts well for the vase. Save it a spot in the fall picture.

A brilliant native for the fall garden — warm-toned daisies in fire colors that feed bees and butterflies late in the season. The name 'sneezeweed' is misleading: it doesn't cause hay fever (the leaves were once dried for snuff). Loves moist soil; cut back by half in June to prevent flopping. Pairs beautifully with asters and grasses.
