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.
Lilium lancifolium is an Asian species of lily, native to China, Japan, Korea, and the Russian Far East. It is widely planted as an ornamental because of its showy orange-and-black flowers, and sporadically occurs as a garden escapee in North America, particularly the eastern United States including New England, and has made incursions into some southern states such as Georgia.
Lilium is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers. They are the true lilies. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the northern hemisphere and their range is temperate climates and extends into the subtropics. Many other plants have "lily" in their common names, but do not belong to the same genus and are therefore not true lilies.
The lily family, Liliaceae, consists of about 15 genera and 610 species of flowering plants within the order Liliales. They are monocotyledonous, perennial, herbaceous, often bulbous geophytes. Plants in this family have evolved with a fair amount of morphological diversity despite genetic similarity. Common characteristics include large flowers with parts arranged in threes: with six colored or patterned petaloid tepals arranged in two whorls, six stamens and a superior ovary. The leaves are linear in shape, with their veins usually arranged parallel to the edges, single and arranged alternating on the stem, or in a rosette at the base. Most species are grown from bulbs, although some have rhizomes. First described in 1789, the lily family became a paraphyletic "catch-all" (wastebasket) group of petaloid monocots that did not fit into other families and included a great number of genera now included in other families and in some cases in other orders. Consequently, many sources and descriptions labelled "Liliaceae" deal with the broader sense of the family.
Lilium martagon, the martagon lily or Turk's cap lily, is a Eurasian species of lily. It has a widespread native region extending from Portugal east through Europe and Asia as far east as Mongolia.
Lilium speciosum is an East Asian species of plants in the lily family. It is native to southern Japan and southern China, where it can be found at elevations of 600–900 metres (2,000–3,000 ft). It is sometimes called the Japanese lily though there are other species with this common name.
Lilium ledebourii is a rare Asian species of plants in the lily family. It was named for German-Estonian botanist Carl Friedrich von Ledebour (1786-1851). Its native range is the Talish region of Azerbaijan, and Damasch in the Amarlu region of Iran.
Hemerocallis fulva, the orange day-lily, tawny daylily, corn lily, tiger daylily, fulvous daylily, ditch lily or Fourth of July lily, is a species of daylily native to Asia. It is very widely grown as an ornamental plant in temperate climates for its showy flowers and ease of cultivation. It is not a true lily in the genus Lilium, but gets its name from the superficial similarity of its flowers to Lilium and from the fact that each flower lasts only one day.
Trillium rugelii, also known as the southern nodding trillium or illscented wakerobin, is a species of flowering plant in the family Melanthiaceae. It is native to parts of the southeastern United States. It is found in the Great Smoky Mountains, Fernbank Forest, Steven's Creek Heritage Preserve, and other places of the Piedmont and southern Appalachian Mountains in Alabama, Georgia, South Carolina, North Carolina and Tennessee. It prefers to grow near streams in humus-rich soil under the shade of deciduous trees.
Allium cernuum, known as nodding onion or lady's leek, is a perennial plant in the genus Allium. It grows in dry woods, rock outcroppings, and prairies. It has been reported from much of the United States, Canada and Mexico including in the Appalachian Mountains from Alabama to New York State, the Great Lakes Region, the Ohio and Tennessee River Valleys, the Ozarks of Arkansas and Missouri, and the Rocky and Cascade Mountains of the West, from Mexico to Washington. It has not been reported from California, Nevada, Florida, Louisiana, Mississippi, New Jersey, Delaware, New England, or much of the Great Plains. In Canada, it grows from Ontario to British Columbia.
Trillium cernuum is a species of flowering plant in the bunchflower family Melanthiaceae. The specific epithet cernuum means "drooping, curving forwards, facing downwards", a distinctive habit of its flower. It is commonly called nodding trillium or nodding wakerobin since the flower is invariably found nodding beneath the leaves. It is sometimes referred to as the northern nodding trillium to distinguish from Trillium rugelii, a similar nodding species native to the southern Appalachian Mountains. It is also called the whip-poor-will flower since presumably its bloom coincides with the spring arrival of the migrating bird with the same name.
Lilium pumilum is an Asian species of bulbous plants native to Mongolia, Siberia, the Russian Far East, Korea and northern China.
Lilium monadelphum is a bulbous plant native to Crimea and to North and South Caucasus.
Lilium pensylvanicum is an Asian plant species of the family Liliaceae. Sometimes called the Siberian lily, it is native to a cold climate and needs frost in the winter. It is found in the wild form in Siberia, the Russian Far East, Mongolia, northeast China, Korea and Hokkaidō.
Lilium hansonii, known as Hanson's lily and Japanese turk's-cap lily, is an East Asian species of plants in the lily family. It is native to Korea, Japan, and to Jilin Province in northeastern China, as well as being widely cultivated as an ornamental.
Lilium distichum is an Asian species herbaceous plant of the lily family which is native to northeastern China, Korea, and eastern Russia.
Lilium debile is a herbaceous plant of the lily family, native to the Russian Far East. It is related to the taller and more widespread species Lilium medeoloides.
Lilium concolor is a species of flowering plant in the lily family which occurs naturally in China, Japan, Korea and Russia. Its relationship with other species is not clear, although it has some similarities to Lilium pumilum.
Lilium polyphyllum is a species of lily endemic to montane environments in central Asia.
