Yellow agoseris is one of my favorites. We have run into patches of these blooms in dry forests, in established, gravelly glades, on south-facing slopes, in burned forests, and on the fringes of open uplands meadows.

• Agoseris glauca is also called short-beaked agoseris, prairie agoseris, or pale agoseris.
• Agoseris is a perennial in the aster family which grows from a long taproot.
• The linear leaves are basal and the stems rise in a range of 10 to 70 cm.
• If stems are broken milky juice (latex) leaks out.
• The yellow ray flowers form a circular composite arrangement.

• There are several similar varieties of agoseris (inc. dysacephala) found in various locations in western North America.
• After flowering, achenes (fruits containing a seed) form (in summer). They are distributed at the end of the season (in fall) as a pappus. Seeds are numerous and viable.
• The latex was used by some First Nations people as a salve or to chew on, like gum.

We have also come across orange agoseris and on rare occasions a pink agoseris, both to be featured in future posts on this site.
