Clintonia is a genus of flowering plants in the lily family Liliaceae. Plants of the genus are distributed across the temperate regions of North America and eastern Asia, in the mesic understory of deciduous or coniferous forests. The genus, first described by Constantine Samuel Rafinesque in 1818, was named for DeWitt Clinton (1769–1828), a naturalist and politician from the U.S. state of New York. For this reason, plants of the genus are commonly known as Clinton's lily. The common name bluebead refer to the distinctive fruit of members of the genus. Since fruit color varies somewhat across species, the common name bead lily is used as well.
Larix laricina, commonly known as the tamarack, hackmatack, eastern larch, black larch, red larch, or American larch, is a species of larch native to Canada, from eastern Yukon and Inuvik, Northwest Territories east to Newfoundland, and also south into the upper northeastern United States from Minnesota to Cranesville Swamp, West Virginia; there is also an isolated population in central Alaska.
Maianthemum canadense is an understory perennial flowering plant, native to Canada and the northeastern United States, from Yukon and British Columbia east to Newfoundland, into St. Pierre and Miquelon. It can be found growing in both coniferous and deciduous forests. The plant appears in two forms, either as a single leaf rising from the ground with no fruiting structures or as a flowering/fruiting stem with two to three leaves. Flowering shoots have clusters of 12–25 starry-shaped, white flowers held above the leaves.
Eurybia macrophylla, commonly known as the bigleaf aster, large-leaved aster, largeleaf aster or bigleaf wood aster, is an herbaceous perennial in the family Asteraceae that was formerly treated in the genus Aster. It is native to eastern North America, with a range extending from eastern and central Canada through the northeastern deciduous and mixed forests of New England and the Great Lakes region and south along the Appalachians as far as the northeastern corner of Georgia, and west as far as Minnesota, Missouri and Arkansas. The flowers appear in the late summer to early fall and show ray florets that are usually either a deep lavender or violet, but sometimes white, and disc florets that are cream-coloured or light yellow, becoming purple as they mature. It is one of the parent species of the hybrid Eurybia × herveyi.
Eurybia divaricata, the white wood aster, is an herbaceous plant native to eastern North America. It occurs in the eastern United States, primarily in the Appalachian Mountains, though it is also present in southeastern Canada, but only in about 25 populations in the provinces of Ontario and Quebec. In the U.S. it is abundant and common, but in Canada it is considered threatened due to its restricted distribution. It has been introduced to a number of countries in Europe. It can be found in dry open woods as well as along wood-edges and clearings. The species is distinguished by its flower heads that have yellow centers and white rays that are arranged in flat-topped corymbiform arrays, emerging in the late summer through fall. Other distinguishing characteristics include its serpentine stems and sharply serrated narrow heart-shaped leaves. The white wood aster is sometimes used in cultivation in both North America and Europe due to it being quite tough and for its showy flowers.
Eurybia is a genus of plants in the family Asteraceae that were previously included in the genus Aster. Most species are native to North America, although one is also present in northern Eurasia. There are 23 species in the genus, including 1 natural hybrid. The name was first applied by Alexandre de Cassini in 1820. The name is derived from Ancient Greek εὐρύς (eurús), meaning "wide", and βαιός (baiós), meaning "few", perhaps in reference to the small number of relatively wide ray florets.
Eurybia schreberi, commonly called Schreber's aster or nettle-leaved Michaelmas-daisy, is a perennial herb in the family Asteraceae. It is native to eastern North America, where it is present in Canada and the United States. The flower heads emerge in the late summer or early fall to show white ray florets and yellow disc florets. It is listed as endangered in Indiana and Iowa, of special concern in Tennessee and possibly extirpated in Maine.
Eurybia surculosa, commonly known as the creeping aster, is an herbaceous perennial in the family Asteraceae that was previously treated in the genus Aster. It is native to the eastern United States where it is found in sandy soils along the coastal plain, though when E. compacta is also present, it exists farther inland in the southern Appalachian Mountains and the Cumberland Plateau. Although the species is not seriously threatened, it is locally endangered in Virginia and Alabama. The flowers, which have bluish violet ray florets and pale yellow disc florets that eventually turn purplish, emerge in summer and persist into the fall.
Eurybia spectabilis, commonly known as the eastern showy aster, simply showy aster or purple wood aster, is an herbaceous perennial native to the eastern United States. It is present along the coastal plain of the U.S. where it is most often found growing in dry, sandy soils. Although it is not considered threatened due to its extensive range, it is locally endangered in many states. The flowers appear in the fall and show ray florets that are a violet-purple and yellow disc florets. It is one of the parent species of the hybrid Eurybia × herveyi.
Eurybia sibirica, commonly known as the Siberian aster or arctic aster, is an herbaceous perennial native to north western North America and northern Eurasia. It is found largely in open areas of subarctic boreal forests, though it is also found in a wide variety of habitats in the region. It is similar in appearance to Eurybia merita, but their ranges overlap only near the border between the US and Canada, where E. sibirica is generally found at higher elevations.
Eurybia paludosa, commonly known as the southern swamp aster, is an herbaceous perennial in the family Asteraceae. It is native to the southeastern United States where it is confined to the Carolinas and the states of Georgia and Florida. It is generally confined to moist soils, though it can occasionally be found on sand hills along the coastal plain. The southern swamp aster is often confused with the closely related southern prairie aster, though they do not occur in the same habitats or geographical areas. Its flower heads emerge in the late summer through fall and show deep lavender to purple rays with yellow centres.
Eutrochium maculatum, the spotted joe-pyeweed, is a North American species of flowering plant in the family Asteraceae. It is widespread through much of the United States and Canada. It is the only species of the genus Eutrochium found west of the Great Plains.
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.
Symphyotrichum pilosum is a perennial, herbaceous, flowering plant in the Asteraceae family native to central and eastern North America. It is commonly called hairy white oldfield aster, frost aster, white heath aster, heath aster, hairy aster, common old field aster, old field aster, awl aster, nailrod, and steelweed. There are two varieties: Symphyotrichumpilosum var.pilosum, known by the common names previously listed, and Symphyotrichumpilosum var.pringlei, known as Pringle's aster. Both varieties are conservationally secure globally and in most provinces and states where they are native.
Solidago rugosa, commonly called the wrinkleleaf goldenrod or rough-stemmed goldenrod, is a species of flowering plant in the family Asteraceae. It is native to North America, where it is widespread across eastern and central Canada and the eastern and central United States. It is usually found in wet to mesic habitats.
Symphyotrichum lanceolatum is a species of flowering plant in the family Asteraceae native to North America. Common names include panicled aster, lance-leaved aster, and white panicled aster. It is a perennial, herbaceous plant that may reach 1.5 meters tall or more, sometimes approaching 2 m. The lance-shaped leaves are generally hairless but may feel slightly rough to the touch on the top because of tiny bristles. The flowers grow in clusters and branch in panicles. They have 16–50 white ray florets that are up to 14 millimeters long and sometimes tinged pink or purple. The flower centers consist of disk florets that begin as yellow and become purple as they mature.
Vaccinium oxycoccos is a species of flowering plant in the heath family. It is known as small cranberry, marshberry, bog cranberry, swamp cranberry, or, particularly in Britain, just cranberry. It is widespread throughout the cool temperate northern hemisphere, including northern Europe, northern Asia and northern North America.
