Plains CoreoPsis  Coreopsis tinctoria
An easy to grow native annual. Good for roadside plantings. It grows in areas with 15 or 
more inches of rainfall all the way to the East Coast. Plains Coreopsis is a good nectar 
plant for butterflies. Native Americans made tea from flowers to strengthen the blood. We 
have used it as a nurse crop in combination with native prairie grass plantings.

Prairie Coneflower  Ratibida columnifera
Cousin to the Mexican Hat, but without the extra splash of “Ole!” the Prairie Coneflower is a 
good nectar plant for butterflies, and unpalatable to deer, goats, sheep and cattle. Prolific and 
easy to grow in almost any well drained soil.

Prairie Goldenrod Solidago nemoralis
One of the shorter goldenrods most common east of the Rockies. Prairie Goldenrod is a 
powerhouse of invertebrate conservation—many varieties of native bees, beetles, butterflies, 
moths, and other native insects visit this plant for pollen & nectar. A great plant to include in 
conservation mixes for horned lizards—many smaller varieties of native ants visit goldenrod 
nectaries, and the hatchling lizards eat the ants.
