Morphology
Ageratum + houstonianum
This is a taxonomic binomial combining the genus name Ageratum (a small-flowered ornamental herb) with a species epithet; the phrase simply refers to that particular plant species rather than an idiomatic meaning. Because it is literal and compositional (genus + specific epithet) rather than metaphorical, a learner who knows the constituents or recognizes binomial naming can infer it denotes a type of Ageratum.
Etymology
Ageratum houstonianum gets its name from two ideas: the first part Ageratum may come from an old word meaning 'not aging' because the small, fluffy flowers keep their color a long time, and the second part houstonianum honors a plant collector named Houston. So the name fits this little herb with fluffy, long-lasting blue flowers.
