The Crassulaceae, also known as the crassulas, the stonecrops or the orpine family, are a diverse family of dicotyledon angiosperms primarily characterized by succulent leaves and a form of photosynthesis known as crassulacean acid metabolism (CAM), in which plants photosynthesize in the daytime and exchange gases during the cooler temperatures of the night. The blossoms of crassulas generally have five floral parts. Crassulaceae are usually herbaceous, though there are some subshrubs, and relatively few trees or aquatic plants.
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.
Echeveria is a large genus of flowering plants in the family Crassulaceae, native to semi-desert areas of Central America, Mexico and northwestern South America.
Dudleya, commonly known as liveforevers, is a genus of rosette-forming succulent plants in the stonecrop family, Crassulaceae, consisting of about 68 taxa in southwestern North America and Guadalupe Island. The species come in many forms, some large and evergreen, others geophytic and deciduous. Yet, despite their dramatic variations in appearance, most species readily hybridize. The flowers of Dudleya have parts numbered in fives, with the petals arranged in tubular, star-shaped, and bell-shaped forms and, when fruiting, are filled with tiny, ovoid-crescent-shaped seeds.
Sedum morganianum, the donkey tail or burro's tail, is a species of flowering plant in the family Crassulaceae, native to southern Mexico. It is a succulent perennial producing trailing stems up to 60 cm (24 in) long, with fleshy blue-green leaves and terminal pink to red flowers in summer. S. morganianum has been found wild in two ravines at Tenampa county, in central Veracruz, in eastern Mexico and on vertical cliffs of igneous rock in the Tropical Deciduous Forest zone. Due to its restricted geographic distribution, it should be regarded as a micro-endemic species.
Dudleya farinosa is a species of succulent plant in the family Crassulaceae known by several common names, including bluff lettuce, powdery liveforever, and powdery dudleya. A coastal plant of northern California and southern Oregon, it is typically found on ocean bluffs just directly above the reach of the waves, and sometimes inland. Its appearance is characterized by lotus-like rosettes of beveled leaves, and in summer the plant erects a tall pink to red peduncle densely covered in bracts, topped with branches of pale yellow flowers. The green or white rosettes of this plant can be seen covering stretches of rocky coast and nearby islets.
Dudleya greenei is a perennial species of succulent plant known by the common names Greene's liveforever, or Greene's dudleya. It is endemic to the Channel Islands of California, where it grows along the cliffs of four of the eight islands. It is a highly variable plant, presenting with multiple forms and varying levels of ploidy. Taxonomically, this species is an insular segregate of Dudleya caespitosa, and was placed as a stopgap taxon by Reid Moran in his 1951 thesis on the genus. It is characterized by white or green leaf rosettes, loomed over by inflorescences bearing pale yellow to white flowers. It is a member of the subgenus Dudleya, as it cannot be propagated from leaf cuttings, does not grow from a corm, and has tight petals.
Echeveria setosa, the Mexican fire cracker, is a species of flowering plant in the family Crassulaceae, native to semi-desert areas of Mexico and common throughout Puebla.
Echeveria elegans, the Mexican snow ball, God's Throne, Mexican gem or white Mexican rose is a species of flowering plant in the family Crassulaceae, native to semi-desert habitats in Mexico.
Echeveria agavoides, or 'lipstick' echeveria, is a species of succulent flowering plant of the stonecrop (sedum) family Crassulaceae, native to the rocky canyons and arid hillsides of Central Mexico. It is primarily known from the states of Aguascalientes, Durango, Guanajuato, Hidalgo, Jalisco, Querétaro, San Luis Potosí and Zacatecas, though it has been sighted as far north as Coahuila and as far south as Oaxaca.
Echeveria runyonii is a species of flowering plant in the family Crassulaceae, that is native to the state of Tamaulipas in Mexico. Several cultivars have been described and cultivated.
Echeveria desmetiana, incorrectly known as Echeveria peacockii, is a succulent plant in the family Crassulaceae. L. de Smet was the first grower of this plant.
Echeveria derenbergii, the painted-lady, is a species of flowering plant in the family Crassulaceae, endemic to Mexico.
Echeveria nodulosa, the 'painted echeveria', is a species of succulent flowering plant in the Crassulaceae (stonecrop) family. Fairly popular in cultivation, it is native to Mexico, where it is widely-distributed, and rather common, in northern Oaxaca and southern Puebla. It is known for its striped, purplish leaves, its "knobby" stems, and its seasonal display of flowers.
Echeveria gibbiflora is a species of flowering plant in the family Crassulaceae. It was described by Swiss botanist Augustin Pyramus de Candolle in 1828. It occurs in Mexico and Guatemala.
Echeveria colorata, is a species of flowering plant in the family Crassulaceae, endemic to Mexico.
Echeveria amoena is a species of succulent plant in the family Crassulaceae, endemic to semi-arid areas of the Mexican states of Puebla, Tlaxcala, and Veracruz.
Echeveria xichuensis is a succulent species of flowering plant in the family Crassulaceae, endemic to Xichú, Guanajuato, Mexico.
Echeveria minima, the miniatureecheveria, is a species of succulent flowering plant in the stonecrop (sedum) family,Crassulaceae, native to northeastern Mexico. Among the many Echeveria species and cultivars, Echeveria minima, in particular, has rather small and diminutive, light-teal blue rosettes edged with pink leaf margins. The attractive, "artichoke"-like rosettes eventually produce enough offsets that they grow into a small colony, forming a low mound. Echeveria minima readily produces yellow, bell-shaped flowers on vertical inflorescences in the spring. A highly collectible succulent, it has gained the Royal Horticultural Society's Award of Garden Merit.
Dudleya cymosasubsp. cymosa is a subspecies of succulent perennial plant in the family Crassulaceae endemic to California. It is the autonymous subspecies for Dudleya cymosa, and is known by the common name canyon liveforever. It is native to the California Coast Ranges, the Sierra Nevada and the Santa Monica Mountains. It is characterized by bright-yellow, orange or red flowers and broad, wide leaves. This plant is commonly found growing on rocky outcrops, talus slopes, and in shaded canyons.
