PurPle Coneflower, narrow leaf Echinacea angustifolia
More rare and more site specific than Echinacea purpurea, this plant likes well drained slopes 
in the tallgrass prairie regions. Good nectar plant for butterflies. Thick stands are rarely found 
in the wild, probably due to over-harvesting in the late 1800s for medicinal uses. All parts of 
this plant including roots can be used for this purpose.

PurPle Prairie Clover  Dalea purpurea var. purpurea
Nature has its own way of healing damaged lands, and this legume is but one of many. It is 
often found growing on severely eroded land or depleted soils, including rocky limestone and 
caliche. The seeds are an important food source for quail and other ground birds.

PurPle nightshade Solanum elaeagnifolium  
Considered a weed by some. Silvery felted leaves reflect sunlight and help it survive 
extreme heat and drought. Exceptionally deep root system, allowing it to persist and 
resprout even under severe disturbance. Its purple flowers require “buzz pollination” by 
native bees, making it ecologically specialized despite its tough, weedy reputation.

rattlesnake Master Eryngium yuccifolium
This unique plant is a botanical enigma. The leaves look like yucca, and the flowers appear 
to be from an alien planet. It's actually a member of the parsley family. The distinctive, 
waxy-green foliage lends the plant a bit of an unusual air, and the white 'spiky golf ball' 
flowers are truly unique.
