Teucrium canadense flowers Flowers.

Teucrium canadense flower Flower close-up.

Flowering - June - September.

Habitat - Prairies, wet meadows, thickets, streambanks, railroads.

Origin - Native to U.S.

Other info. - This species can be found throughout Missouri. The unusual flowers of this species make it a simple to ID in the field. The flowers are also quite showy and make the plant much deserving of cultivation. Flying insects are attracted to the flowers and the large central lobe of the lower corolla lip serves as a platform for insects to land on. The two purplish spots on the lobe are like runway lights guiding the insects to the flower.
The leaves of T. canadense have a slightly fowl odor when crushed.
Some authors, including Steyermark, split the species into different varieties but they are so similar that I won't go into them here.

Photographs taken at Logan Creek, Reynolds County, MO., 6-29-03.
