Erect, bushy, short-lived perennial with green, slightly cupped, shiny, toothed leaves. Flowers — both ray and disk — are bright yellow with curling scales beneath. Aptly named for the sticky resinous substance covering the flower buds prior to opening. Slightly odorous. Often grows in patches. Can be invasive.
A member of the aster family.
Roadsides, saline flats, disturbed sites.
North American aboriginals used the flowers and leaves for treating bronchitis & asthma and as a wash for healing sores.
