Cornus florida, the flowering dogwood, is a species of flowering tree in the family Cornaceae native to eastern North America and northern Mexico. An endemic population once spanned from southernmost coastal Maine south to northern Florida and west to the Mississippi River. The tree is commonly planted as an ornamental in residential and public areas because of its showy bracts and interesting bark structure.
Actaea racemosa, the black cohosh, black bugbane, black snakeroot, rattle-top, or fairy candle, is a species of flowering plant of the family Ranunculaceae. It is native to eastern North America from the extreme south of Ontario to central Georgia, and west to Missouri and Arkansas. It grows in a variety of woodland habitats, and is often found in small woodland openings. The roots and rhizomes were used in traditional medicine by Native Americans. Its extracts are manufactured as herbal medicines or dietary supplements. Most dietary supplements containing black cohosh are not well-studied or recommended for safe and effective use in treating menopause symptoms or any disease. In contrast, some herbal medicinal products containing black cohosh extract hold a marketing authorization in several states of the European Union and are well-studied and recommended for safe and effective use for the relief of menopausal symptoms such as hot flushes and profuse sweating attacks. Such differentiation between the product types seems to be important.
Trillium grandiflorum, the white trillium, large-flowered trillium, great white trillium, white wake-robin or French: trille blanc, is a species of flowering plant in the family Melanthiaceae. A monocotyledonous, herbaceous perennial, the plant is native to eastern North America, from northern Quebec to the southern parts of the United States through the Appalachian Mountains into northernmost Georgia and west to Minnesota. There are also several isolated populations in Nova Scotia, Maine, southern Illinois, and Iowa.
Solanum carolinense, the Carolina horsenettle, is not a true nettle, but a member of the Solanaceae, or nightshade family. It is a perennial herbaceous plant, native to the southeastern United States, though its range has expanded throughout much of temperate North America. The plant is an invasive in parts of Europe, Asia, and Australia. The stem and undersides of larger leaf veins are covered with prickles.
Aegopodium podagraria, commonly called ground elder, is a species of flowering plant in the carrot family Apiaceae that grows in shady places. The name "ground elder" comes from the superficial similarity of its leaves and flowers to those of elder (Sambucus), which is not closely related. Other common names include herb gerard, bishop's weed, goutweed, gout wort, snow-in-the-mountain, English masterwort and wild masterwort. It is the type species of the genus Aegopodium. It is native to Europe and Asia, but has been introduced around the world as an ornamental plant, where it occasionally poses an ecological threat as an invasive exotic plant.
Verbascum thapsus, the great mullein, greater mullein or common mullein, is a species of mullein native to Europe, northern Africa, and Asia, and introduced in the Americas and Australia.
Clintonia borealis is a species of flowering plant in the lily family Liliaceae. The specific epithet borealis means "of the north," which alludes to the fact that the species tends to thrive in the boreal forests of eastern Canada and northeastern United States.
Asclepias syriaca, commonly called common milkweed, butterfly flower, silkweed, silky swallow-wort, and Virginia silkweed, is a species of flowering plant. It is native to southern Canada and much of the United States east of the Rocky Mountains, excluding the drier parts of the prairies. It is in the genus Asclepias, the milkweeds. It grows in sandy soils as well as other kinds of soils in sunny areas.
Adenostoma fasciculatum, commonly known as chamise or greasewood, is a flowering plant native to California and Baja California. This shrub is one of the most widespread plants of the California chaparral ecoregion. Chamise produces a specialized lignotuber underground and at the base of the stem, known as a burl, that allow it to resprout after fire has off burned its stems. It is noted for its greasy, resinous foliage, and its status as one of California's most iconic chaparral shrubs.
Caulophyllum thalictroides, the blue cohosh, is a species of flowering plant in the Berberidaceae (barberry) family. It is a medium-tall perennial with blue berry-like fruits and bluish-green foliage. The common name cohosh is probably from an Algonquian word meaning "rough". The Greek-derived genus name Caulophyllum signifies "stem-leaf", while the specific name thalictroides references the similarity between the large highly divided, multiple-compound leaves of meadow-rues and those of blue cohosh.
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from either parent. Asexual reproduction produces new individuals without the fusion of gametes, resulting in clonal plants that are genetically identical to the parent plant and each other, unless mutations occur.
Coptis trifolia, commonly known as the threeleaf goldthread or savoyane, is a perennial plant in the genus Coptis, a member of the family Ranunculaceae.
Berberis trifoliolata is a species of flowering plant in the family Berberidaceae, in southwestern North America. Common names include agarita, agrito, algerita, currant-of-Texas, wild currant, and chaparral berry. The name Agarita comes from the Spanish verb agarrar, which means "to grab". The ending "-ita" is often added to little things, so agarita means "grabs a little". This was probably said because the bush is a bit scratchy but does not have significant spines. Typical characteristics are grey-green to blue-grey leaves, yellow flowers in February to April and the red berries appearing in May. The most important harvest organ are the berries, though the roots and seeds can also be used.
Thaumatococcus daniellii, also known as miracle fruit or miracle berry, is a plant species from tropical Africa of the Marantaceae family. It is a large, rhizomatous, flowering herb native to the rainforests of western Africa in Sierra Leone, southeast to Gabon and the Democratic Republic of the Congo. It is also an introduced species in Australia and Singapore.
Pontederia cordata, common name pickerelweed (USA) or pickerel weed (UK), is a monocotyledonous aquatic plant native to the Americas. It grows in a variety of wetlands, including pond and lake margins across an extremely large range from eastern Canada south to Argentina. A few examples include northern rivers, the Everglades and Louisiana.
Persoonia lanceolata, commonly known as lance-leaf geebung, is a shrub native to New South Wales in eastern Australia. It reaches 3 m (10 ft) in height and has smooth grey bark and bright green foliage. Its small yellow flowers grow on racemes and appear in the austral summer and autumn, followed by green fleshy fruits which ripen the following spring. Within the genus Persoonia, P. lanceolata belongs to the lanceolata group of 58 closely related species. It interbreeds with several other species found in its range.
Caulophyllum giganteum, the northern blue cohosh, is a species of flowering plant in the barberry family. It is native primarily to northeastern North America, where it is found in rich forests.
Iris typhifolia is a species in the genus Iris, also the subgenus Limniris and in the series Sibiricae. It is a rhizomatous herbaceous perennial, from China. It has slender, twisted leaves, deep green slender hollow stem and 2 violet-blue flowers. It is cultivated as an ornamental plant in temperate regions.

Stellera is a genus of flowering plant in the family Thymelaeaceae, with a single species Stellera chamaejasme found in mountainous regions of Central Asia, China, Siberia and South Asia. S. chamaejasme is a herbaceous perennial plant with heads of white, pink or yellow flowers, grown as an ornamental plant in rock gardens and alpine houses, but considered a weed playing a rôle in the desertification of grasslands in parts of its native range. Like many others of its family, it is a poisonous plant with medicinal and other useful properties.
