Allium hollandicum, the 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 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 (35 in) tall. It has long, flat, strap-shaped leaves up to 60 cm (24 in) long. Umbels are relatively small and spherical, up to 10 cm (3.9 in) in diameter, composed of many purple to reddish-purple star-shaped flowers appearing in late spring and early summer.[11][12][13]
The popular cultivar 'Purple Sensation' has gained the Royal Horticultural Society's Award of Garden Merit.[3] It prefers moist, fertile soil in full sun.
