Morphology
The compound follows a straightforward modifier+noun pattern: 'pea' signals a plant and 'butterfly' describes a salient property (butterfly-like flowers or association with butterflies). This compositional relation is common and allows a B1 learner who knows both words to infer it denotes a type of pea/flowering plant.
Etymology
Butterfly pea comes from the plant's bright blue flowers that look like a small butterfly and from the fact the plant belongs to the pea family. So the name points to the climbing plant often grown for its blue or purple blooms and used to make 'herbal tea'.
