Morphology
Tanacetum + cinerariifolium
This is a Latin binomial (taxonomic) name rather than a compositional English phrase; one constituent ('cinerariifolium') is not an ordinary English word and the label encodes a species identity and usage (source of pyrethrum) that is encyclopedic rather than derivable from the parts. Scientific names are language-neutral labels and do not transparently convey the everyday meaning to a B1 learner, so the overall meaning cannot be predicted from the constituents.
Etymology
Tanacetum cinerariifolium gets its long name from how it looks and how people used it: Tanacetum is a kind of herb called tansy and cinerariifolium means 'ash-leaf' because the leaves are pale and silky underneath. People crushed its white flowers to make 'pyrethrum', a 'natural insecticide' that kills bugs, so the name fits a pale-leaved plant used as a bug killer.
