Orange Coneflower (Rudbeckia fulgida)

Under most natural circumstances, Orange Coneflower would be found in very wet habitats including sedge meadows, fens and edges of swamps and other marshy areas.  That is if you were to ever find it in a natural setting.  According to the U of M Herbarium database, Rudbeckia fulgida has a C-Value of 9 out of 10 making it very rare and highly unlikely that you would encounter it in the wild (at least in southern Michigan where most of it's natural habitat has been destroyed).  In September, I was very fortunate to not only find this plant growing on our property, but to find it blooming (which means it will be producing seeds).  There were only one or two plants where I found it growing on the edge of a wooded area, where a thick patch of gray dogwood borders the yard.  The inflorescence is almost identical to that of Black-Eyed Susan (Rudbeckia hirta) which is why I almost passed it by.  The leaves however, are very different in that they're larger, ovate in shape and have coarse-toothed margins.  Shown in the photo below, this specimen was found growing in a fine-textured clay/loam soil capable of holding lots of moisture which explains it's occurrence in an upland setting.  Despite the common name Orange Coneflower, this plant is actually in the same Genus as Black-Eyed Susan's (Rudbeckia).

Conversely, Black-Eyed Susan rates at a C-Value of 1 out of 10, one reason why it is found more commonly.  They also tolerate a larger range of soil moisture categories which allows them to compete well across a larger range of habitats.  The leaves are smaller, have smooth margins and are thick and velvety.
