Mangave
Mangaves are plants formerly given the nothogenus name × ''Mangave''. They are derived from hybridizing species in the genus ''Agave'' and the former genus ''Manfreda''. ''Manfreda'' is now included in ''Agave'', so the scientific name is obsolete. Mangaves are often employed as ornamental plants in dry environments, as they possess traits of durability found in both parents. Around 30–40 cultivars were available . Development The name × ''Mangave'' was first coined in 2005 by Tony Avent of Plant Delights Nursery and Carl Schoenfeld and Wade Roitsch of Yucca Do Nursery to describe two plants growing at Yucca Do Nursery in Hempstead, Texas. The plants originated from seed collected as ''Manfreda'' in the wild in Northern Mexico that were growing adjacent to plants of '' Agave mitis'' (''A. celsii''). Only two seedlings from the original seed batch were hybrids. Another cultivar of the plant, 'Bloodspot', was the product of breeding '' Agave maculata'' (then k ...

Agave
''Agave'' (; ; ) is a genus of monocots native to the hot and arid regions of the Americas and the Caribbean, although some ''Agave'' species are also native to tropical areas of North America, such as Mexico. The genus is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves. ''Agave'' now includes species formerly placed in a number of other genera, such as ''Manfreda'', ×''Mangave'', ''Polianthes'' and ''Prochnyanthes''. Many plants in this genus may be considered perennial, because they require several to many years to mature and flower. However, most ''Agave'' species are more accurately described as monocarpic rosettes or multiannuals, since each individual rosette flowers only once and then dies; a small number of ''Agave'' species are polycarpic. Maguey flowers are considered edible in many indigenous culinary traditions of Mesoamerica. Along with plants from the closely related genera ''Yucca'', ''Hes ...

Micropropagation
Micropropagation or tissue culture is the practice of rapidly multiplying plant stock material to produce many progeny plants, using modern plant tissue culture methods. Micropropagation is used to multiply a wide variety of plants, such as those that have been genetically modified or bred through conventional plant breeding methods. It is also used to provide a sufficient number of plantlets for planting from seedless plants, plants that do not respond well to vegetative reproduction or where micropropagation is the cheaper means of propagating (e.g. Orchids.) Cornell University botanist Frederick Campion Steward discovered and pioneered micropropagation and plant tissue culture in the late 1950s and early 1960s. Steps In short, steps of micropropagation can be divided into 4 stages. # Selection of mother plant # Multiplication # Rooting and acclimatizing # Transfer new plant to soil Selection of mother plant Micropropagation begins with the selection of plant material to b ...

Agavoideae
Agavoideae is a subfamily of monocot flowering plants in the family Asparagaceae, order Asparagales. It has previously been treated as a separate family, Agavaceae. The group includes many well-known desert and dry-zone types, such as the agaves and yuccas (including the Joshua tree). About 640 species are placed in around 23 genera; they are widespread in the tropical, subtropical, and warm temperate regions of the world. Description and uses Species may be succulent or not. In general, Agavoideae leaves occur as rosettes at the end of a woody stem, which may range from extremely short to tree-like heights, as in the Joshua tree. The leaves are parallel-veined, and usually appear long and pointed, often with a hardened spine on the end, and sometimes with additional spines along the margins. ''Agave'' species are used to make ''tequila, pulque,'' and ''mezcal'', while others are valued for their fibers. They are quite popular for xeriscaping, as many have showy flowers. Sy ...

Garden Plants Of North America
A garden is a planned space, usually outdoors, set aside for the cultivation, display, and enjoyment of plants and other forms of nature. The single feature identifying even the wildest wild garden is ''control''. The garden can incorporate both natural and artificial materials. Gardens often have design features including statuary, follies, pergolas, trellises, stumperies, dry creek beds, and water features such as fountains, ponds (with or without fish), waterfalls or creeks. Some gardens are for ornamental purposes only, while others also produce food crops, sometimes in separate areas, or sometimes intermixed with the ornamental plants. Food-producing gardens are distinguished from farms by their smaller scale, more labor-intensive methods, and their purpose (enjoyment of a hobby or self-sustenance rather than producing for sale, as in a market garden). Flower gardens combine plants of different heights, colors, textures, and fragrances to create interest and delight the se ...

Drought-tolerant Plants
Drought tolerance is the ability to which a plant maintains its biomass production during arid or drought conditions. Some plants are naturally adapted to dry conditions'','' surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. Other plants, specifically crops like corn, wheat, and rice, have become increasingly tolerant to drought with new varieties created via genetic engineering. The plants behind drought tolerance are complex and involve many pathways which allows plants to respond to specific sets of conditions at any given time. Some of these interactions include stomatal conductance, carotenoid degradation and anthocyanin accumulation, the intervention of osmoprotectants (such as sucrose, glycine, and proline Proline (symbol Pro or P) is an organic acid classed as a proteinogenic amino acid (used in the biosynthesis of proteins), although it does not contain the amino group but is rather a secondary amine.

Celsius
The degree Celsius is the unit of temperature on the Celsius scale (originally known as the centigrade scale outside Sweden), one of two temperature scales used in the International System of Units (SI), the other being the Kelvin scale. The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale or a unit to indicate a difference or range between two temperatures. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale in 1742. Before being renamed in 1948 to honour Anders Celsius, the unit was called ''centigrade'', from the Latin ''centum'', which means 100, and ''gradus'', which means steps. Most major countries use this scale; the other major scale, Fahrenheit, is still used in the United States, some island territories, and Liberia. The Kelvin scale is of use in the sciences, with representing absolute zero. Since 1743 the Celsius scale has been based on 0 °C for the freezing ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Succulent Plant
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulent plants may store water in various structures, such as leaf, leaves and Plant stem, stems. The water content of some succulent organs can get up to 90–95%, such as ''Glottiphyllum semicyllindricum'' and ''Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in Alpine climate, alpine ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agave Macroacantha
''Agave macroacantha'', the black-spined agave or large-thorned agave, is a species of succulent flowering plant in the family Asparagaceae naturally occurring in Oaxaca and also near the town of Tehuacan in the State of Puebla, Mexico. Description ''Agave macroacantha'' produces a medium-sized leaf rosette that can be basal or can grow on a very short stem. Leaves are succulent, greyish green and up to 1.8 feet long at a maximum, ending in sharp black spines that are up to 1.2 inches long at the tips. Flowers are small, grey and red, growing in bunches on sturdy stems of up to 3 m (10 feet) in height. Cultivation The plant prefers a dry, sunny and hot location for summer and from early autumn onwards a cooler, well-lit space. It likes regular watering in summer and only minimum watering in winter, and will fare well in a large pot with sparse, gravelly soil. In the UK this plant has gained the Royal Horticultural Society The Royal Horticultural Society (RHS), founded i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid Name
In botanical nomenclature, a hybrid may be given a hybrid name, which is a special kind of botanical name, but there is no requirement that a hybrid name should be created for plants that are believed to be of hybrid origin. The '' International Code of Nomenclature for algae, fungi, and plants'' (ICNafp) provides the following options in dealing with a hybrid: * A hybrid may get a name; this will usually be the option of choice for naturally occurring hybrids. * A hybrid may also be indicated by a formula listing the parents. Such a formula uses the multiplication sign "×" to link the parents. ** "It is usually preferable to place the names or epithets in a formula in alphabetical order. The direction of a cross may be indicated by including the sexual symbols (♀: female; ♂: male) in the formula, or by placing the female parent first. If a non-alphabetical sequence is used, its basis should be clearly indicated." (H.2A.1) * Grex names can be given to orchid hybrids. A hybrid ...

Agave Maculata
''Agave maculata'' ( synonym ''Manfreda maculosa''), commonly known as the Texas tuberose or spice lily, is a species of ''Agave'' that is endemic to southern Texas and northeastern Mexico. Description The Texas tuberose is acaulescent, meaning the stem is extremely short. The fleshy silvery-green leaves are covered with purple spots and in low light situations may lay flat on the ground. In a drought, the leaves may wither, leaving little or nothing visible above ground. Sufficient precipitation yields an inflorescence tall in the period April–September. The new flower stalks (inflorescences) are fed on by small mammals, javelina, deer, and feral pigs, which can end the flowering effort for that season. The leaves are fed on by these as well, especially during droughts, weakening and killing the plants. The flowers open and change colors over 3–4 days of life, from white to pink to dark red. The inferior ovaries turn from green to purple to black as they mature as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agave Mitis
''Agave mitis'' is a plant species native to the Mexican states of Hidalgo, Tamaulipas Tamaulipas (), officially the Free and Sovereign State of Tamaulipas ( es, Estado Libre y Soberano de Tamaulipas), is a state in the northeast region of Mexico; one of the 31 states which, along with Mexico City, comprise the 32 Federal Entiti ... and San Luis Potosí, referred to as ''Agave celsii'' in many publications. ''Agave mitis'' forms rosettes of blue-green to yellow-green, fleshy leaves up to 60 cm (2 feet) long. The leaves have soft brown spines not nearly as imposing as those of other agaves. The flowering stalk is up to 2.5 m (8 feet) tall, with the flowers closely appressed against the stem forming a narrow column much more compact than most other species of the genus. Flowers are green, each up to 60 mm (2.4 inches) long. Because the species is widespread and grows in several protected areas, it is not considered by the IUCN to be threatened. References F ...
