Most people know Sulfur Cinquefoil as the plant that looks like marijuana but has yellow flowers.  I described it that way on a recent weed walk at our farm and the 14 year old daughter in the group said "Oh yeah!  I know that one."  The look she got from her mother was priceless.  

Most conservation departments want this plant gone and one state even has a "Wanted Dead NOT Alive" poster penned just on cinquefoil's behalf.   

Before pulling all of these plants or spraying them, consider their benefit
