Helenium / Sneezeweed
Common Name: Sneezeweed
Helenium species make a wonderful addition to most summer gardens. With good sun and moderate water, these plants will bloom for many weeks, beginning in early summer. They attract many native bees, including sweat bees, bumble bees, long-horned bees and leafcutter bees. On the west coast, Helenium is a magnet for Agapostemon (green sweat bees) and Coelioxys (cuckoo bees).
