There were just so many wonderful hand-painted plant studies in this book from 1858. Some talented artist, who was not credited for their work, colorized this flower image over 150 years ago.
The flower of the yellow cowslip shown in this picture is actually a flower head comprised of a number of individual flower buds with yellow petals and maroon accents. A single leaf accompanies the flower giving a feel for what an entire plant looks like.
Hopefully, this vintage botanical illustration of cowslip will be useful to someone in their own creative endeavors.
Lessons From the Vegetable World included a number of flower illustrations. They were published in 1858 and now illustrator or watercolorist was credited for the work.
