Morphology
rocket + cress
The compound combines two plant names ('rocket' = arugula-like salad green; 'cress' = a small leafy plant), so a B1 learner who knows both words would reasonably infer it denotes a type of plant. However, the specific taxonomic identity and the sense 'a noxious wild species (Sisymbrium/hedge mustard)' and its negative connotation are not directly predictable from the parts, making the meaning only partially derivable.
Etymology
Rocket cress joins rocket and cress; rocket comes from an old word 'roquette' for a 'peppery' salad leaf and cress means a small edible herb. So the name points to a wild, 'peppery' plant with yellow flowers, which is why we use it today for that common weed.
