Morphology

blue + cardinal + flower

The elements 'blue' and 'flower' transparently signal a flower of blue colour, but 'cardinal' normally denotes a deep red and here functions as a lexicalized species name ('cardinal flower'). Because the phrase relies on a conventional plant name whose internal semantics conflict with the adjective 'blue', a B1 learner could infer a blue flower but would not fully predict the exact botanical sense without exposure.

Etymology

Blue cardinal flower gets its name from the older plant called cardinal flower, whose bright red blooms reminded people of a 'cardinal' (a church leader) in red robes. Adding blue just tells you this type has blue blooms, so the name helps you imagine a tall flower with blue spikes.
