How to use this prompt

Real field-guide plates carry Latin captions, but SDXL renders lettering as convincing gibberish that ruins the antique illusion — so "text, labels, handwriting" go in the negative and you typeset a species name yourself afterward, which also lets you sell the same art with different captions. "Foxing spots" is the age cue that matters: it reads as a found archival print, and the mottled paper texture usefully hides upscaler artifacts when you push to 300 DPI. Keep cfg at 6.5, because higher contrast blackens the hatching until the plate looks photocopied rather than engraved. The 3:4 ratio frames cleanly at 12x16 and 18x24, the classic botanical-set sizes buyers hang in threes.

Variations to try

  • Eucalyptus version — "a single eucalyptus sprig with round silver-green leaves" on the same aged paper for a matching set
  • Chart version — "three small fern species arranged in a row, comparative botanical study" for a wider statement piece
