Simple Botanical Drawings
/Draw 50 Flowers, Trees, and other Plants by Lee J. Ames with P. Lee Ames. Available from Internet Archive here.
The drawing diagrams in this book are not at the level of botanical prints but they are a start toward producing plant drawings. If I wanted to create botanical prints, I would quickly graduate to drawing from fresh plant models. For now, I am taking a different direction - using the instruction diagrams as starters for upcoming Zentangles where it is OK for the drawing to not look realistic in the end!
My two favorites are the instructional pages for producing drawings of Skunk Cabbage and a Calla Lilly. These are the one I’ll experiment with first.
