From Middle English enbuschen, from Old French enbuscier, anbuchier (verb) (whence Middle French embusche (noun)), from Old French en- + Vulgar Latin boscus (“wood”) (whence also bouquet), from Frankish busk (“bush”), from Proto-Germanic buskaz (“bush, heavy stick”). Compare ambuscade. The change to am- from earlier forms in en- is unexplained. More at bush.
