Cercis canadensis, the eastern redbud, is a large deciduous shrub or small tree, native to eastern North America from southern Michigan south to central Mexico, west to New Mexico. Species thrive as far west as California and as far north as southern Ontario. It is the state tree of Oklahoma. The prevalence of the so-called "Columbus strain" has seen the residents of Columbus, Wisconsin embrace the plant into their city's identity. Known as the "Redbud City," the town hosts "Redbud Day" annually the Saturday before Mother's Day, organizing a variety of themed events to recognize the tree.
Taxus canadensis, the Canada yew or Canadian yew, is a conifer native to central and eastern North America, thriving in swampy woods, ravines, riverbanks and on lake shores. Locally called simply "yew", this species is also referred to as American yew or ground-hemlock.
A bur is a seed or dry fruit or infructescence that has hooks or teeth. The main function of the bur is to spread the seeds of the bur plant, often through epizoochory. The hooks of the bur are used to latch onto fur or fabric, enabling the bur – which contain seeds – to be transported to another location for dispersal. Another use for the spines and hooks are physical protection against herbivores. Their ability to stick to animals and fabrics has shaped their reputation as bothersome.
Sanicula marilandica, the Maryland sanicle or Maryland black snakeroot, is a flowering plant widespread in North America but rare along the Pacific coast of the continent and Texas. Sanicula marilandica is listed as Sensitive in Washington state.
Sanicula arctopoides is a species of sanicle known commonly as footsteps of spring, bear's foot sanicle or yellow mats. It is a perennial herb found on the west coast of the United States and Canada, especially near the ocean. The branches are short and thick and may be prostrate or slightly erect. The leaves are yellowish-green and carrot-like or maple-shaped, and the tiny yellow flowers are borne in umbels with prominent bracts. The plants grow in low matted patches along the ground, resembling "footsteps" of yellow against the background.
Sanicula is a genus of plants in family Apiaceae, the same family to which the carrot and parsnip belong. This genus has about 45 species worldwide, with at least 22 in North America. The common names usually include the terms sanicle or black snakeroot.
Sicyos angulatus, the oneseed bur cucumber or star-cucumber is an annual vine in the gourd family, Cucurbitaceae, native to eastern North America. The plant forms mats or climbs using tendrils. The leaves are palmately veined and lobed, the flowers are green to yellowish green, and the fruits form clusters of very small pepos.
Circaea lutetiana, known as broad-leaved enchanter's nightshade, is a plant in the evening primrose family, Onagraceae.
Calamagrostis canadensis is a species of grass, having three or more varieties, in the family Poaceae. It is known variously by the common names of bluejoint, bluejoint reedgrass, marsh reedgrass, Canadian reedgrass, meadow pinegrass, Canada bluejoint and marsh pinegrass.
Echinocystis is a monotypic genus in the gourd family, Cucurbitaceae. The sole species is E. lobata, commonly called wild cucumber, prickly cucumber or bur cucumber. It is an annual, sprawling plant that is native to North America.
Sanicula bipinnatifida is a species of flowering plant in the parsley family known by the common names purple sanicle, purple blacksnakeroot, and shoe buttons. It is native to the west coast of North America from British Columbia to Baja California, where it can be found in many types of habitat, including grassland, woodlands, and mountain slopes of serpentine soils.
Sanicula hoffmannii is an uncommon species of flowering plant in the family Apiaceae known by the common names Hoffmann's blacksnakeroot and Hoffmann's sanicle. It is endemic to California, where it is known from the Channel Islands and a few locations in the coastal mountain ranges of the mainland, including the Scott Creek watershed in Santa Cruz County. Its habitat includes coastal hillsides and mountain slopes, sometimes with serpentine soils. It is a perennial herb producing a thick stem up to 90 centimeters tall from a taproot. The green or bluish leaves are compound, the blades each divided into about three lobed, toothed leaflets. The inflorescence is made up of one or more heads of bisexual and male-only flowers with tiny, curving, yellow-green petals.
Sanicula maritima is a rare species of flowering plant in the parsley family known by the common names adobe snakeroot and adobe sanicle.
Sanicula saxatilis is a rare species of flowering plant in the parsley family known by the common names devil's blacksnakeroot and rock sanicle.
Sanicula tracyi is a species of flowering plant in the family Apiaceae known by the common names Tracy's blacksnakeroot and Tracy's sanicle. It is endemic to northwestern California, where it is known from woodlands and coniferous forest in hills and mountains. It is a perennial herb producing a slender stem up to about 60 centimeters tall from a taproot. The leaves are compound, divided into usually three leaflets which are deeply cut into lobes and serrated along the edges. The herbage is green to purple in color. The inflorescence is made up of one or more heads of bisexual and male-only flowers with tiny, curving, yellow petals. The fruits are 2 or 3 millimeters long, each fruit covered in bumpy tubercles and sometimes with prickles near the tip.
Sanicula tuberosa is a species of flowering plant in the parsley family known by the common name turkey pea. It is native to western North America from Oregon through California to Baja California, where it can be found in many types of habitat, including chaparral, forests, and woodlands. It is variable in appearance. In general, it is a perennial herb producing a slender stem up to 80 centimeters long from a small, spherical tuber no more than 2 centimeters wide. The leaves are compound, divided into usually three leaflets which are smooth or deeply cut into lobes. The herbage is green to purple in color. The inflorescence is made up of one or more heads of bisexual and male-only flowers with tiny, curving, yellow petals. The fruits are 1 or 2 millimeters long and covered in bumpy tubercles.
Spergularia canadensis is a species of flowering plant in the family Caryophyllaceae, known by the common name Canadian sandspurry. It is native to North America, where it is known from mainly coastal habitat. It is found along the coastline of Canada and northern parts of the United States, from Alaska to northern California on the West Coast, and as far south as New York on the East Coast.
Orbexilum pedunculatum, commonly known as Sampson's snakeroot, is a species of flowering plant in the legume family. It is native primarily to the Southeastern United States where it is found in prairies and savannas, often in acidic soil. It is a perennial that produces racemes of flowers in early summer.
Sparganium americanum, American bur-reed, is a perennial plant found in the United States of America and Canada. Though this species resembles a grass, it is a type of bur-reed. This species is important for conservation purposes because it has the ability to remove nitrogen and phosphorus runoff from water, like many other wetland species. By doing this, it protects waterways from excess nitrogen which can cause eutrophication. This increased nitrogen is especially a problem during the farmers’ growing season. During this same time frame the S. americanum is growing and taking up nitrogen.
Sanicula odorata, commonly called the clustered blacksnakeroot, is a flowering plant in the family Apiaceae. It is native and widespread in eastern North America. It grows in nutrient-rich woods, often in mesic forests and bottomlands. It is able to tolerate somewhat degraded habitats, and is not considered a particularly conservative species.
