Morphology
The compound follows a transparent noun+noun pattern that signals a type of 'broom' (a shrub), so a B1 learner who knows both words would likely infer it is a kind of shrub. However, the modifier 'indigo' here refers to a taxonomic/lexical element rather than a predictable color or obvious property, and the specific botanical sense (a yellow-flowering species) is not derivable from the constituents. Because the overall class (a broom shrub) is clear but the precise meaning/use of 'indigo' is not, the expression is only partially predictable.
Etymology
Indigo broom comes from two simple images: broom is a many‑branched shrub that looks like a cleaning brush, and indigo was once a name for some related plants or for dye plants. So the name came to mean this upright, branchy herb with bright yellow flowers.
