Here's a cheery plant, with its yellow glow on a spring morning brightening up even shady areas under the trees and in the forests.  
 
     Golden Groundsel's daisy-like flowers bloom in sun or shade, and Golden Groundsel self sows, and it spreads aggressively, forming thick, evergreen mats, which are great for tamping out invasives and other weeds.
 
     Golden Groundsel is host to the threatened Northern Metalmark and other moth larvae, and it attracts lots of other pollinators.
