Sabatia angularis, commonly called rosepink, [3] rose pink, [4] square-stem rose pink [1] or rose gentain [5] is a biennial flowering plant in the Gentianaceae (gentain) family. It is native to central and eastern North America.
S. angularis grows 0.8–0.9 metres (2.5–3 ft) tall, although in the first year this biennial plant appears only as a low rosette of leaves. In the second year, one or more stems rise from the basal leaves. The stems are 4-sided, appearing as a square in cross section, and glabrous, with flexible, thin wings on the edges. The lower part of the main stem is unbranched, with branches growing primarily from leaf nodes on the upper part. The leaves are opposite, simple, entire (without teeth), glabrous, ovate to ovate-lanceolate, and measure up to about 3.8 centimetres (1.5 in) long and 2.5 centimetres (1 in) wide. [4] [6]
The plant blooms from June to September with fragrant pink (occasionally white) flowers that are up to 2.5 centimetres (1 in) across. [7] The flowers have 5 petal-like obovate lobes. Yellowish triangular markings on the inner edge of the lobes give the appearance of a star in the middle of the flower. [4] After the flowers fade, the plant produces seed capsules that contain numerous tiny seeds. Seeds are spread by the wind, and the plant will reseed itself.
The genus name honors Liberato Sabbati, an 18th century Italian botanist. The specific epithet is Latin for "angular", referring to the square stems. [7]
It is geographically widespread in the United States, in the southern U.S. from Arizona in the west all the way to the east coast, and in the northern U.S. from Illinois in the west to Massachusetts in the east. It is native to Ontario but it is believed to be extirpated. [8]
S. angularis is found in a variety of habitats, in glades, along roadsides, in fields, and along the margins of woods. [7]
Campsis radicans, the trumpet vine, yellow trumpet vine, or trumpet creeper, is a species of flowering plant in the family Bignoniaceae, native to eastern North America, and naturalized elsewhere. Growing to 10 metres, it is a vigorous, deciduous woody vine, notable for its showy trumpet-shaped flowers. It inhabits woodlands and riverbanks, and is also a popular garden plant.
Sabatia campestris is a species of Sabatia, native to the south-central United States, from Texas east to Mississippi and north to Iowa and Illinois. It is also locally naturalized in New England.
Hibiscus laevis, the halberd-leaf rosemallow, is a herbaceous perennial flower native to central and eastern North America. Their showy, creamy-white or pink flowers are large, up to 15 centimetres (6 in) across, and are hard to miss. These flowers require exposure to sunlight to open up properly, and then last only a single day.
Mertensia virginica is a spring ephemeral plant in the Boraginaceae (borage) family with bell-shaped sky-blue flowers, native to eastern North America.
Cunila origanoides, with the common names stone mint, frost mint, dittany, and American dittany, is a perennial late-summer-flowering subshrub with small purple flowers that is native to the central and eastern United States. It belongs to the Lamiaceae (mint) family and is the only species in the Cunila genus native to the United States. It grows in habitats such as dry forests and the thin soil around rock outcrops. This species has historically been cultivated for use as a medicinal herb, tea, and ornamental plant.
Sabatia stellaris, with the common names rose of Plymouth, marsh pink, salt-marsh pink, and sea-pink; is a species of Sabatia. It has the synonym Sabatia maculata (Benth.) Benth. & Hook.f., Sabatia palmeri Gray, Sabatia purpusii Brandeg., Sabatia simulata Britt.).
Echinacea atrorubens, called the Topeka purple coneflower, is a North American species of flowering plant in the family Asteraceae. It is native to eastern Kansas, Oklahoma, and eastern Texas in the south-central United States. It is found growing in dry soils around limestone or sandstone outcroppings and prairies.
Echinacea simulata, commonly called wavy leaf purple coneflower, glade coneflower, or prairie purple coneflower, is a species of perennial flowering plant in the family Asteraceae. It is native to the east-central states of the United States. Its natural habitat is dry, calcareous, open areas such as barrens and woodlands.
Sabatia, the rose gentians, is a genus of about 20 species of flowering plants in the family Gentianaceae, native to eastern and central North America, Central America, and the Caribbean.
Artemisia biennis is a species of sagebrush known by the common name biennial wormwood. It is a common and widely distributed weed, so well established in many places that its region of origin is difficult to ascertain. This species is most likely native to northwestern North America and naturalized in Western Europe, and eastern and southern North America.
Tradescantia ozarkana, the Ozark spiderwort, is a species of Tradescantia. It is part of the Commelinaceae family, native to the States of Missouri, Arkansas, and Oklahoma in the south-central United States. It flowers from April to May and can be found in rich, rocky areas, including woods and bluff ledges.
Prunus rivularis, known variously by the common names creek plum, hog plum, or wild-goose plum is a thicket-forming shrub. It prefers calcareous clay soil or limestone-based woodland soils. This deciduous plant belongs to the rose family, Rosaceae, and is found mainly in the central United States. It is a shrub consisting of slender stems with umbel clusters of white blossoms. The fruit is a drupe that resembles a large berry; though it has a bitter taste, it serves as a source of food for birds and other wildlife. "Prunus" is Latin for plum, whereas "rivularis" means being near a stream.
Asclepias quadrifolia, commonly called four-leaved milkweed or fourleaf milkweed, is a species of milkweed in the Apocynaceae (dogbane) family. It is sometimes referred to as whorled milkweed, but it should not be confused with Asclepias verticillata. A. quadrifolia occurs in the eastern United States and Canada.
Mimulus alatus, the sharpwing monkeyflower, is an herbaceous eudicot perennial that has no floral scent. It is native to North America and its blooming season is from June to September. The flowering plant has green foliage and blue to violet flowers. It has a short life span compared to most other plants and a rapid growth rate. Like other monkey-flowers of the genus Mimulus, M. alatus grows best in wet to moist conditions and has a bilabiate corolla, meaning it is two-lipped. The arrangement of the upper and lower lip petals suggests a monkey’s face. The winged stems together with the monkey face give the plant its common name.
Monarda bradburiana, the eastern beebalm or Bradbury's beebalm, is a species of perennial flowering plant in the mint family, Lamiaceae, that is native to much of the southeastern United States.
