Morphology

California + fern

The phrase combines a place name 'California' plus the head noun 'fern', so its basic meaning — a type or variety of fern associated with California — is directly derivable from the constituents. While specific botanical details (biennial habit, toxicity) are not predictable from the words alone, the referential category (a kind of fern) is transparent to learners who know both words.

Etymology

California fern may come from people seeing a leafy plant in California that looked like a fern. California points to where it grows and fern to its fern-like leaves, so the name creates an image that helps you remember it is 'not a true fern' and is 'poisonous'.
