Allium hollandicum, common names Persian onion[1][2] or Dutch garlic[3] is a species of flowering plant native to Iran and Kyrgyzstan[4] but widely cultivated as an ornamental because of its large umbels of attractive purple flowers.[5][6][7] It is reportedly naturalized in Saint Louis County, Minnesota.[8][9][10]

Allium hollandicum is a bulb-forming perennial with scapes up to 90 cm tall. It has long, flat, strap-shaped leaves up to 60 cm long. Umbels are large and spherical, up to 25 cm in diameter, with many purple to reddish-purple flowers.[11][12][13]

The cultivar ‘Purple Sensation’ has gained the Royal Horticultural Society’s Award of Garden Merit.[3]
