How to use this prompt

A cyanotype is a contact print, so the plants must be pure silhouette — the prompt says "white silhouettes" and bans "color" and "photorealistic" in the negative to hold the two-tone look. The tell of a real cyanotype is the "soft and slightly uneven" sun-printed edge, so that phrase is load-bearing; crisp digital edges give the game away, which is why "harsh digital edges" is in the negative. Keep the arrangement to a central frond with a scatter of small leaves rather than a stated count — counting fronds invites the model to drop some. Prussian blue is named because generic blue drifts toward sky blue.
