Rough Blazing-Star     Liatries aspera


Description: Rough Blazing-star is a native, warm-season perennial herb belonging to family Compositae, or daisy family. It attains a height of up to 90 cm. It has a rounded, underground bulb (corm).   

 

Leaf: The alternate, linear leaves are rough and narrow. The upper leaves are sessile and shorter.                                                   

 

Flower:  Its spike of numerous (may be over 100), rounded, rose-purple flower heads makes an impressive show in the native prairie. Each flower head contains 25 to 40 flowers with numerous, irregularly toothed bracts on a short stalk or no stalk.

Discussion: Rough blazing star was thought to be useful in the treatment of snakebite. Early Americans dug the corms and stored them for food. The tea used for snakebites was also used to treat stomach aches. These plants are important aesthetically as they brighten the yellows of autumn with contrasting purple.

 

Distribution: Rough Blazing-star occurs in dry or sandy soil and, in Illinois, it exists in several types of prairie. This species occurs throughout the range of True Prairie.    

 

Native or Introduced to Illinois: Native
