Often growing in small bushy clumps, this bright sunflower is long-lived and abundant in summer and fall mountain meadows, frequently brightening many acres. It is also very common along roadsides.  Its long, narrow leaves are almost an olive drab. Flowers start with a green central disk and tiny green rays, gradually changing to golden disks and golden-yellow rays.

"Helios" is Greek for "sun" and "meris" for "part of".

William Gambel collected the first specimen of this plant, probably in the 1840s, and it was named Heliomeris multiflora in 1848 by his mentor, Thomas Nuttall.  Weber and the Synthesis accept this name.   S. F. Blake renamed the plant Viguiera multiflora in 1918 and that is the name that Intermountain Flora accepts. Alexandre L. Viguier, 1790-1867, was a physician and botanist in Montpellier, Vermont.

As you might have noticed on the trail, Heliomeris multiflora's central disk of flowers looks quite green and dark when young and then quite golden-yellow when it matures.  The close-up of a maturing flower at left shows why: stamens emerge from the multitude of tiny central disk tubular flowers and then yellow pollen tips the stamens and gives the maturing flower an increasingly golden-yellow appearance.
