Vernonia baldwinii Western Ironweed grows wild from Texas and Louisiana North into South Dakota and Minnesota.  It can be planted and will grow over a large portion of the US.

Vernonia = Named for William Vernon, 17th century English botanist
baldwinii = Named for Dr. William Baldwin,
              19th century physician and the initial botanist on
              Stephen Long's expedition to find the headwaters of the Missouri River

Vernonia baldwinii Western Ironweed's vivid purple flowers are effective when planted with the yellow flowers of Goldenrod in late summer and fall. They are stunning as cut flowers but the leaves should be discarded before arranging.  It is a member of the Aster family, with numerous 3/4 inch flower heads in rounded or flat topped branching clusters and a favorite nectar source for butterflies.  Vernonia baldwinii Western Ironweed plants are avoided by cattle and are often abundant in old fields and pastures.  Plant Ironweed in humus rich soil in full sun at the back of a perennial garden on naturalize in a meadow or prairie.  

Western Ironweed is also known as  Baldwin's Ironweed
Native Wild Vernonia baldwinii Western Ironweed plants occur naturally in prairies, glades, meadows, pastures, and along roadsides from South Dakota and Minnesota South to Louisiana and Texas. 
 Asteraceae (Aster family)

 Prairie ironweed prefers full sun and moist fertile soil but will grow in partial sun and slightly moister or drier conditions. This plant can withstand occasional flooding for short periods of time. The foliage is not grazed by cattle or bothered by pests or disease to any significant extent.

Vernonia fasciculata is a native perennial unbranched plant 2 to 4 feet tall. The central stem is round, hairless, and white, light green, or reddish purple. The alternate leaves are up to 5" long and ½" across. They are narrowly lanceolate, narrowly ovate, or linear. Their margins are serrated, while the upper and lower leaf surfaces are hairless. The lower leaf surface also has a prominent central vein, and black dots may be present. The leaves are sessile against the stem, or they have short petioles. The central stem terminates in a flat-topped cluster of magenta compound flowers (i.e., a corymb). This flower cluster is quite dense, rather than loose and spreading. The flowering stalks may be slightly pubescent. A compound flower consists of 15-30 disk florets with a short cylinder of green bracts underneath. These bracts are appressed together like fish scales, and they are often slightly ciliate. The cylinder of bracts spans about 1/5" across. A disk floret is magenta, with 5 spreading lobes and a prominent divided style. The blooming period occurs from late summer to early fall, and lasts about a month. There is no noticeable floral scent. The flowers are replaced by achenes that have a pappus of hair-like scales. These achenes can be blown several feet from the mother plant by gusts of wind. The root system is spreading and fibrous.

Prairie Ironweed is fairly common in the Midwest and Eastern US in prairies, riverbottom prairies, marshes, sloughs along railroads, and edges of fields. Prairie Ironweed is found in wetland habitats to a greater extent than other species of Ironweeds.

The flowers attract long-tongued bees, butterflies, and skippers primarily. Other visitors include bee flies and Halictid bees. These insects seek nectar, although bees also collect pollen. Among the long-tongued bees, are such visitors as bumblebees, Epeoline cuckoo bees, Miner bees, and large Leaf-Cutting bees. An oligolectic bee of Ironweeds is Melissodes vernoniae. The caterpillars of several moths feed on Ironweed, including Grammia parthenice (Parthenice Tiger Moth) and Perigea xanthioides (Red Groundling). Caterpillars that bore into the roots or stems of Ironweed include Papaipema cerussata (Ironweed Borer Moth), Carmenta bassiformis (Eupatorium Borer Moth), and some Polygrammodes spp. (Pyralid Moths). The bitter foliage of Ironweed deters consumption by mamamalian herbivores – it is known as an 'increaser' because it is one of the last plants to be eaten in overgrazed pastures.

Additional common names for Prairie Ironweed are Smooth Ironweed and Common Ironweed. Prairie Ironweed is one of the smaller Ironweeds with a compact inflorescence and smooth hairless leaves. Other Ironweed species have hairy stems or leaves. An exception is Vernonia gigantea (Tall Ironweed), which has hairless leaves and stems upon occasion. However, Tall Ironweed has a spreading inflorescence, and it is usually a taller plant (as the name implies). The larger leaves of Tall Ironweed exceed ½" across, while the leaves of Smooth Ironweed are ½" or less. Some authorities state that Smooth Ironweed has black dots on the undersides of the leaves, but this is not always true. The species in this genus are occasionally difficult to identify because they can hybridize with each other.

ommon Name: western ironweed
Type: Herbaceous perennial
Family: Asteraceae
Native Range: Central and central southern United States
Zone: 3 to 9
Height: 3.00 to 5.00 feet
Spread: 1.00 to 1.50 feet
Bloom Time: July to September
Bloom Description: Purple
Sun: Full sun
Water: Dry to medium
Maintenance: Low
Flower: Showy
Tolerate: Deer, Drought, Dry Soil, Shallow-Rocky Soil

Easily grown in average, dry to medium, well-drained soils in full sun. Tolerates both moist and dry soils. Plants grow taller in moist soils. Overall plant height may be reduced by cutting back stems nearly to the ground in late spring. Remove flower heads before seed develops to avoid any unwanted self-seeding. Easily grown from seed.

Western ironweed (sometimes called Baldwin's ironweed) is native to Missouri where it typically occurs in dry woods, meadows, prairies, glades, fields, waste areas and along railroad tracks throughout the State. Although many of the ironweeds are indigenous to wetland areas, this species is one that is commonly found in drier soils including the Great Plains. It is a coarse, upright perennial typically growing 3-4' (infrequently to 5') tall on stiff, leafy stems which branch at the top. Composite flowers with fluffy, purple disks (rays absent) appear in flattened, loose, terminal clusters (corymbs) which bloom from late summer to fall. Rough, pointed, serrate, lance-shaped leaves (4-7" long). Flowers give way to rusty seed clusters. The source of the common name has been varyingly attributed to certain "iron-like" plant qualities including tough stems, rusty-tinged fading flowers and rusty colored seeds. Species name is in reference to William Baldwin who has been credited with first collecting the plant. Flowers are very attractive to butterflies.
No serious insect of disease problems.
Naturalize in cottage gardens, wildflower meadows, prairies or native plant gardens. Also effective as a background plant for borders.
