This flower goes by quite a few different common names eg Black Eyed Susan, poorland daisy, brown betty, yellow daisy. I went with Yellow Daisy. It is native to Eastern and Central North America and is also used as a traditional Native American Medicinal Herb.
I used a more textured watercolour paper for this one as I wanted a bit of texture in the background. Really pleased with how it turned out.
Yellow Daisy measures 3.5 x 2.5 inches and is painted on Daler - Rowney 'The Langton' NOT 300gsm watercolour paper.
Many thanks to Sue Farris for the reference photo.
