Flower Anatomy Diagram
Stable DiffusionFlower Anatomy Diagram is an SDXL prompt for a 3:4 infographic. A vintage botanical chart of a lily cross-section with callout lines to six parts — petal, stamen, pistil, sepal, stem and leaf — in soft pink, sage green and sepia on cream produces an educational anatomy diagram with no text.

How to use this prompt
"Cross-section of a lily flower" is the subject instruction that gives the model a specific flower to render; a generic "flower" produces inconsistent anatomy. Six plain callout lines are the annotation system that makes this a diagram, not a botanical painting — but never name the parts in the prompt: naming petal or stamen beside a callout line makes the model letter the boxes with garbled pseudo-Latin. "Completely empty label box with nothing written inside" reserves the space for labels the user adds later. "19th-century botanical illustration style with fine ink linework" is the rendering convention that matches educational science charts; a modern style would clash with the vintage-chart aesthetic. "No numbers" prevents the model from adding garbled reference numerals.
Variations to try
- Swap the lily for a sunflower cross-section for a composite flower anatomy chart
- Change the palette to deep blue and white for a cyanotype botanical chart variant
