Trillium is a genus of about fifty flowering plant species in the family Melanthiaceae. Trillium species are native to temperate regions of North America and Asia, with the greatest diversity of species found in the southern Appalachian Mountains in the southeastern United States.
Trillium erectum, the red trillium, also known as wake robin, purple trillium, bethroot, or stinking benjamin, is a species of flowering plant in the family Melanthiaceae. The plant takes its common name "wake robin" by analogy with the European robin, which has a red breast heralding spring. Likewise Trillium erectum is a spring ephemeral plant whose life-cycle is synchronized with that of the forests in which it lives. It is native to the eastern United States and eastern Canada from northern Georgia to Quebec and New Brunswick.
Primula is a genus of herbaceous flowering plants in the family Primulaceae. They include the primrose, a familiar wildflower of banks and verges. Other common species are P. auricula (auricula), P. veris (cowslip), and P. elatior (oxlip). These species and many others are valued for their ornamental flowers. They have been extensively cultivated and hybridised. Primula are native to the temperate Northern Hemisphere, south into tropical mountains in Ethiopia, Indonesia, and New Guinea, and in temperate southern South America. Almost half of the known species are from the Himalayas.
The Primulaceae, commonly known as the primrose family, are a family of herbaceous and woody flowering plants including some favourite garden plants and wildflowers. Most are perennial though some species, such as scarlet pimpernel, are annuals.
Hepatica is a genus of herbaceous perennials in the buttercup family, native to central and northern Europe, Asia and eastern North America. Some botanists include Hepatica within a wider interpretation of Anemone.
Persicaria maculosa is an annual plant in the buckwheat family, Polygonaceae. Common names include lady's thumb, spotted lady's thumb, Jesusplant, and redshank. It is widespread across Eurasia from Iceland south to Portugal and east to Japan. It is also present as an introduced and invasive species in North America, where it was first noted in the Great Lakes region in 1843 and has now spread through most of the continent.
Androsace, commonly known as rock jasmine, is a genus of flowering plants in the family Primulaceae, second only to Primula in the number of species. It is predominantly Arctic–alpine, with many species in the Himalayas, the mountains of central Asia, the Caucasus, and the southern and central European mountain systems, particularly the Alps and the Pyrenees.
Pseudotrillium is a monotypic genus of flowering plant in the family Melanthiaceae. Its sole species, Pseudotrillium rivale, is commonly known as the brook wakerobin. It is endemic to the Siskiyou Mountains of southern Oregon and northern California. The Latin specific epithet rivale means “growing by streams”, with reference to a preferred habitat.
Tiarella, the foamflowers, is a genus of flowering plants in the family Saxifragaceae. The generic name Tiarella means "little turban", which suggests the shape of the seed capsules. Worldwide there are seven species, one each in eastern Asia and western North America, plus five species in eastern North America. As of October 2022, the taxonomy of Tiarella in eastern North America is in flux.
Tiarella trifoliata, the three-leaf foamflower, is a species of flowering plant in the family Saxifragaceae. The specific name trifoliata means "having three leaflets", a characteristic of two of the three recognized varieties. Also known as the laceflower or sugar-scoop, the species is found in shaded, moist woods in western North America.
Paracryphia is a genus of a single species, Paracryphia alticola, a small tree or shrub endemic to New Caledonia in the family Paracryphiaceae. Its closest relative is Sphenostemon.
Pomatosace is a genus of flowering plant in the family Primulaceae, with only one species, Pomatosace filicula, endemic to the Qinghai–Tibetan Plateau in China.
Androsace albana is a species of flowering plant in the primrose family, Primulaceae. It is native to Iran, the Transcaucasus and Turkey. It was first described by Christian von Steven in 1812.
Androsace vitaliana is a species of plant in the primrose family, Primulaceae. It was previously known by the synonym Vitaliana primuliflora. Native to the high mountains of Europe, it is cultivated as an alpine garden plant, being considered easy to grow in well drained soil in a sunny position.
Androsace americana, synonym Douglasia arctica, known as the Mackenzie River dwarf primrose, is a species of flowering plant in the primrose family, Primulaceae. It is native to subarctic North America.
Primula frenchii, French's shootingstar, is a species of flowering plant in the family Primulaceae. It is native to the central and southern United States, in southern Illinois, Indiana, Kentucky, Arkansas, and Alabama. It grows in moist, shady areas such as ledges near streams and under sandstone cliffs.
Symphyotrichum potosinum is a species of flowering plant in the family Asteraceae native to Mexico and the U.S. state of Arizona. Commonly known as Santa Rita Mountain aster, it is a perennial, herbaceous plant that may reach heights of 15 to 45 centimeters.
Lysimachia × commixta is a hybrid of flowering plants in the primrose family Primulaceae. It is native to eastern North America, from eastern Canada across the Great Lakes region west to Minnesota. The hybrid specific epithet commixta means "mixed together, mixed up", which presumably refers to the genetic mixing of two species. Indeed, the hybrid is sometimes referred to as the mixed loosestrife or the commingling loosestrife.
Trillium hibbersonii is a species of flowering plant in the bunchflower family Melanthiaceae. The specific epithet hibbersonii honors the English Canadian surveyor John Arthur Hibberson (1881–1955) who first collected this plant in 1938 on Vancouver Island in British Columbia. Hibberson and his son propagated the trilliums, selling them to buyers in England and other European countries. In 1968, Leonard Wiley coined the Latin name Trillium hibbersonii, a name that has since been used by horticulturists without reservation.
Androsace nivalis is a species of flowering plant in the primrose family Primulaceae with the common name snow dwarf-primrose. It was previously placed in the genus Douglasia, which is now known to be nested within Androsace.
