Morphology
The phrase is a straightforward adjective + noun composition: 'lesser' modifies 'knapweed', signalling a smaller or subordinate variety of that plant, so a learner who knows both words can infer it denotes a type of knapweed. This is a regular, non-idiomatic naming pattern (common in plant names and across languages), so the meaning is directly derivable from the constituents.
Etymology
Lesser knapweed may come from an old word for knap meaning a small rounded 'knob', because the plant's tight, round flower heads look like little bumps. The word lesser means 'smaller' and weed shows it is a wild plant, so the name says 'a smaller wild plant with knobbly flower heads'.
