Morphology
The meaning 'the broad, flat part of a leaf' is directly and compositionally derived from 'leaf' (plant organ) + 'blade' (broad flat area); both constituents refer to plant-related concepts and the compound follows a straightforward noun+noun naming pattern. This is a common, cross-linguistic descriptive construction, so a B1 learner who knows both words would readily understand the MWE.
Etymology
Leaf blade comes from putting together leaf and blade, because blade has long been used for things that are thin and flat, like a knife or a blade of grass. That flat image helps explain the meaning: the wide, flat part of a leaf, not the stalk, so it means 'the broad, flat part of a leaf'.
