I saw this photo and thought I could identify funky cauliflower shapes in the unopened buds. I didn’t have that reaction to the actual flower (what does that say about me?). So, I checked out scientific names, and it turns out that they (Daucus carota and Brassica oleracea)are not closely related at all. Ancestral populations suggest origins in temperate Europe and southwest Asia vs very southern and western Europe, so no huge spatial overlap.
End economic botany discussion.
