Interesting Facts
A treasured family heirloom plant that was commonly passed from one family member to another, the common corn-flag was first introduced to the United States in the early 1800s. Typically planted along with grains, its bulbs were buried deep within the ground to keep them from getting plowed and helping them to survive.
Name Story
Common corn-flag: The plant is introduced in 1576 and its earlier name is common corn-flag. "Flag" refers to its iris-like leaves and "corn" originally meant all grains. With its bulbs deep enough to avoid the ploughshare, it has served as an ornamental plant in farm fields since ancient times which is quite similar to Papaver rhoeas which is still called corn poppy to this day.
