Morphology

Penstemon + serrulatus

This is a scientific binomial (genus + Latin species epithet). While a learner who knows the genus 'Penstemon' will recognise it as a type of plant, the second element 'serrulatus' is a Latin form not part of general English vocabulary and does not transparently yield the descriptive meaning to a B1 learner. Understanding the full sense requires botanical/Latin knowledge, so the compound is not compositional for typical learners.

Etymology

Penstemon serrulatus is named for how the plant looks: Penstemon means 'beardtongue' (the small hairy part inside the flower) and serrulatus means 'small saw' (the tiny teeth on the leaf edges), so the name helps you picture the blue flowers with a hairy 'tongue' and saw-like leaves.
