Echinacea is a genus of herbaceous flowering plants in the daisy family. It has ten species, which are commonly called coneflowers. They are native only in eastern and central North America, where they grow in moist to dry prairies and open wooded areas. They have large, showy heads of composite flowers, blooming in summer. The generic name is derived from the Greek word ἐχῖνος, meaning "hedgehog", due to the spiny central disk. These flowering plants and their parts have different uses. Some species are cultivated in gardens for their showy flowers. Two of the species, E. tennesseensis and E. laevigata, were formerly listed in the United States as endangered species; E. tennesseensis has been delisted due to recovery and E. laevigata is now listed as threatened.
Tirania purpurea, the sole species in genus Tirania, is a species of climbing plant endemic to Vietnam. This genus is related to Forchhammeria and Stixis, but the placement of these three is uncertain. They were placed in Capparaceae until DNA studies showed them to be more closely related to Resedaceae that to Capparaceae. They are sometimes placed in their own family Stixaceae, but since it is not yet clear whether they are from a clade, they are better left in Brassicales unplaced at family rank.
Actaea, commonly called baneberry, bugbane and cohosh, is a genus of flowering plants of the family Ranunculaceae, native to subtropical, temperate and subarctic regions of Europe, Asia and North America.
Bauhinia × blakeana, commonly called the Hong Kong orchid tree, is a hybrid leguminous tree of the genus Bauhinia. It has large thick leaves and striking purplish red flowers. The fragrant, orchid-like flowers are usually 10 to 15 centimetres across, and bloom from early November to the end of March. Although now cultivated in many areas, it originated in Hong Kong in 1880 and apparently all of the cultivated trees derive from one cultivated at the Hong Kong Botanical Gardens and widely planted in Hong Kong starting in 1914. It is referred to as bauhinia in non-scientific literature though this is the name of the genus. It is sometimes called the Hong Kong orchid. In Hong Kong, it is most commonly referred to by its Chinese name of 洋紫荊 (yèuhng jígīng).
Digitalis purpurea, the foxglove or common foxglove, is a toxic species of flowering plant in the plantain family Plantaginaceae, native to and widespread throughout most of temperate Europe. It has also naturalized in parts of North America, as well as some other temperate regions. The plant is a popular garden subject, with many cultivars available. It is the original source of the heart medicine digoxin. This biennial plant grows as a rosette of leaves in the first year after sowing, before flowering and then dying in the second year. It generally produces enough seeds so that new plants will continue to grow in a garden setting.
Theobroma is a genus of flowering plants in the mallow family, Malvaceae, that is sometimes classified as a member of Sterculiaceae. It contains roughly 20 species of small understory trees native to the tropical forests of Central and South America.

It is most common in the Ozarks and in the Mississippi/Ohio Valley. Its habitats include dry open woods, prairies and barrens.
Limosella is a genus of flowering plants known as mudworts. These are annual, largely aquatic plants, found in muddy areas worldwide. Its phylogeny and biogeography are inferred from molecular data.

Dalea purpurea is a species of flowering plant in the legume family known as purple prairie clover. Native to central North America, purple prairie clover is a relatively common member of the Great Plains and prairie ecosystems.
