Culver’s-Root     Veronicastrum virginicum


Description: Culver’s-root is a native, warm-season, tall perennial herb, which attains a height of up to one and one-half meters. It is a member of the Scrophulariaceae, figwort, or snapdragon family.

 

Leaf: The slender, sharp-toothed leaves occur in whorls of three to seven around the tall, straight stem, which accounts for another common name, whorlywort.

 

Flower: The fragrant, white tubular flowers are many, but small and densely crowded. There may be up to nine flower heads on a stem. The flower tubes have two projecting stamens.

 

Blooming months: July-August

 

Stem: The stem is tall and straight. 

 

 

 

 

 

 

 

 

 

 

 

Discussion: Early medicinal uses dealt mainly with the digestive system. Its early use as a physic lent itself to another common name, culver’s physic. Apparently the root has cathartic (bowel cleansing) qualities.

 

Distribution: In Illinois, this species grows along railroad and highway rights-of-way where relict patches of prairie occur. The habitat is one of good soil and moist condition. It also occurs in dry woods. Culver’s-root ranges from the New England states to Minnesota, Missouri, and Texas.

 

Native or Introduced to Illinois: Native
