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.
The Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic.
Aeonium, the tree houseleeks, is a genus of about 35 species of succulent, subtropical plants of the family Crassulaceae. Many species are popular in horticulture. The genus name comes from the ancient Greek "αιώνιος"/"aionios" (ageless). While most of them are native to the Canary Islands, some are found in Madeira, Cape Verde, Morocco, in East Africa and Yemen.
Sedum is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species, subsequently reduced to 400–500. They are leaf succulents found primarily in the Northern Hemisphere, but extending into the southern hemisphere in Africa and South America. The plants vary from annual and creeping herbs to shrubs. The plants have water-storing leaves. The flowers usually have five petals, seldom four or six. There are typically twice as many stamens as petals. Various species formerly classified as Sedum are now in the segregate genera Hylotelephium and Rhodiola.
Aeonium arboreum, the tree aeonium, tree houseleek, or Irish rose, is a succulent, subtropical subshrub in the flowering plant family Crassulaceae.
Aeonium nobile is a succulent, subtropical flowering plant in the family Crassulaceae. It is native to the island of La Palma in the Canary Islands, where it grows on dry slopes and cliffs at altitudes up to 800m. The inflorescences are large and spreading with bright red flowers.
Trillium cuneatum, the little sweet Betsy, also known as whip-poor-will flower, large toadshade, purple toadshade, and bloody butcher, is a species of flowering plant in the family Melanthiaceae. It is native to the southeastern United States but is especially common in a region that extends from southern Kentucky through central Tennessee to northern Alabama. In its native habitat, this perennial plant flowers from early March to late April. It is the largest of the eastern sessile trilliums.
Aeonium haworthii, also known as Haworth's aeonium or pinwheel, is a species of succulent flowering plant in the family Crassulaceae. It is grown as a houseplant in temperate regions. It has gained the Royal Horticultural Society's Award of Garden Merit, as has the cultivar ‘Variegatum’.
Aeonium undulatum is a succulent, evergreen flowering plant in the family Crassulaceae. It is a subshrub, one of the larger species of Aeonium with an 8–12 inches (200–300 mm) rosette of bright, glossy green leaves often over a metre from the ground on a single, unbranched stem. Other rosettes do not branch off this stem (normally) but grow from the bottom, unlike most aeoniums. The plant is monocarpic so the flowering stem will die when after producing its yellow inflorescence, which is normally after about 5 years.
Aeonium leucoblepharum is a succulent flowering plant in the family Crassulaceae. The pointed leaves have a strong central stripe, and they may develops pinkish colour on exposure to strong sunlight. There are variants with less pointed leaves but still with the central stripe. The flowers are yellow, 7- to 10-merous, with petals 6 – 8 x 1.8 – 2.5 mm. The species is native to mountains in Yemen and north-eastern Africa, from Ethiopia and Somalia to Kenya and Uganda. It is also known as Sempervivum leucoblepharum and Sempervivum chrysanthum.
Aeonium glutinosum is a species of flowering plant in the family Crassulaceae endemic to Madeira, Portugal. It has fairly thick leaves and its appearance varies depending on its growing conditions. One characteristic is the very sticky stem of the inflorescence. The main flower is shown but small stalks with flowers continue to appear for several months.
Aeonium hierrense is a species of succulent flowering plant in the family Crassulaceae that is endemic to the island of El Hierro in the Canary islands. It has whorls of strongly ciliate leaves borne on a stem up to 1m in height. The leaves takes on an attractive purple colour during the summer, being quite green in the winter. It produces whitish pink flowers that have 8-fold symmetry.
Aeonium tabuliforme, the flat-topped aeonium or saucer plant, is a species of succulent plant in the family Crassulaceae, native and endemic to Tenerife in the Canary Islands. It is low-growing, typically reaching about 5 cm high but up to 45 cm in diameter. It grows on moist, north-facing cliffs and ledges at low altitude. A mass of fleshy, hairy, bright green leaves in flat rosettes is produced on short unbranched stems, often on vertical surfaces. This species is short-lived and dies after flowering. Plants often take 3-4 years to flower, at which point they produce a tall raceme of yellow flowers.
Aeonium canariense is a species of flowering plant in the family Crassulaceae. It is endemic to the island of Tenerife in the Canary Islands, where it grows on dry slopes and cliffs in the north of the island from sea level to about 1300m. It forms large rosettes of leaves close to the ground but the spikes of yellow flowers stand up to 70 cm tall.
Rhododendron cuneatum (楔叶杜鹃) is a rhododendron species native to northern and western Yunnan and southwestern Sichuan in China, where it grows at altitudes of 2,700–4,300 m (8,900–14,100 ft). It is an erect evergreen shrub that grows 4–6 ft (1.2–1.8 m) in height, with leaves that are narrowly to broadly elliptic or oblong-lanceolate, 1–7 × 0.5–2.8 cm in size. The flowers are usually a deep rose colour.
Aeonium sedifolium is a perennial flowering plant in the stonecrop family Crassulaceae. The plant is native to the western Canary Islands of Tenerife, La Gomera and La Palma.
Conospermum amoenum, commonly known as blue smokebush, is a shrub endemic to Western Australia
Aeonium balsamiferum is a species of tropical flowering plant in the family Crassulaceae. The species is endemic in the Canary Islands.
Aeonium aureum is a species of flowering plant in the family Crassulaceae, native to the Canary Islands. It has very short stems, usually with several leaf rosettes. The grey-green leaves are tightly packed and fleshy. The bright yellow flowers are produced on leafy stems, and are up to 25 mm (1 in) across.
Aeonium dodrantale is a species of tree houseleek in the family Crassulaceae.
