Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

[Italian : bella, feminine of bello, beautiful (from Latin bellus; see deu- in Indo-European roots) + donna, lady; see Donna (the plant perhaps being so called because women of Italian courts during the Renaissance are said to have used the juice of belladonna berries to make their eyes more attractive by dilating their pupils) .]

from Wiktionary, Creative Commons Attribution/Share-Alike License

From Italian bella donna, literally 'beautiful lady', altered by folk etymology from Medieval Latin bladona 'nightshade', from Gaulish. The folk etymology was motivated by the cosmetic use of nightshade for dilating the eyes.
