Helenium flower seed is a native American perennial, so you know it is right at home in the sunny garden. The plant can reach 48 inches tall and 18 inches wide, with dozens of flowering stems. It is a magnet for bees, and it needs to be deadheaded to keep blooming. It makes a great cut flower, so take all you want because Helenium will just keep producing more blooms.
Helenium is also known as Common Sneezeweed or Dogtooth Daisy. This name was given because its foliage irritates the skin of some people. Wear gloves the first few times you handle the plant. The flowers, however, are allergen-free, so the cut flowers can be brought indoors for vases without any worry.
Sneezeweed seeds can take from 14 - 21 days to germinate, and temperatures needs to be at least 70F degrees for germination to take place. Cover the flower seed lightly with top soil. Once the plants are growing well, pinch them back in the spring by 8 - 10 inches, just above a new set of leaves. This will encourage bushier growth, but it will also delay blooming until later in the summer. Helenium plants need plenty of water throughout the growing season. Cut Autumn Sneezeweed back to the ground after flowering. It is a long-lived perennial that will thrive for many years in your garden. Divide the plant every few years for best results.
