Helenium
Seed Packet

Helenium

Helenium autumnale
Helenium grows lustily in the summer with beautiful, healthy green leaves and a vigorous shrubby form. In midsummer, the broad-petaled daisies bloom, attracting bees and butterflies to the raised button centers. The name sneezeweed refers to the historical use of the ground dried leaves and flowers as a snuff with medicinal benefits. It prospers in moist, well-drained soils and full sun in meadow gardens and borders and pairs beautifully with grasses.

PLACEMENT & CULTIVATION
A beautiful native flower, Helenium or sneezeweed, is found in wet meadows and along sunny pond edges. It seamlessly transitions to humus-rich soil in borders, where its bright flowers enliven midsummer and fall gardens and pair beautifully with grasses. Cut back in early June to promote additional branching and flowering and a more manageable size that will not need staking. Deadhead, if desired, for extended bloom, or allow the seedheads to add interest to late fall and winter gardens. Deer-resistant, it attracts butterflies, bees, and beneficial insects and is a host plant for some butterfly caterpillars. Divide every 3-4 years. Caution: contains some toxic elements.
Final Spacing:
1.5-3'
