Not my best work. Posting anyway. When doing botanical sketches/watercolors, I'm always on the fence about the background. What to do. Leave it blank, or with a muted colorwash fill? Try to approximate the actual background in a blurry way? I think the most successful botanical sketches I've done have used the texture/form of the plant as an abstract element in the background. Or I could go all Georgia O'Keeffe and just say "there shall be no background!"
