Desert Garden Conservatory
The Desert Garden Conservatory is a large botanical greenhouse and part of the Huntington Library, Art Collections and Botanical Gardens, in San Marino, California. It was constructed in 1985. The Desert Garden Conservatory is adjacent to the Huntington Desert Garden itself. The garden houses one of the most important collections of cacti and other succulent plants in the world, including a large number of rare and endangered species. The Desert Garden Conservatory serves The Huntington and public communities as a conservation facility, research resource and genetic diversity preserve. John N. Trager is the Desert Collection curator. There are an estimated 10,000 succulents worldwide, about 1,500 of them classified as cacti. The Huntington Desert Garden Conservatory now contains more than 2,200 accessions, representing more than 43 plant families, 1,261 different species and subspecies, and 246 genera. The plant collection contains examples from the world's major dese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cactus Garden
A cactarium or cactuario (from Latin, ''cactarium'') is a garden dedicated to the planting of cacti. While they generally specialize in collecting cacti, they can also include other desert plants such as sabla, agaves or Crassulaceae, although this would better be termed "xeriscaping''"''. Cacti are succulent plants native to the American continent, typical of arid environments. They require dry conditions and therefore, in many countries, the collections are kept in greenhouses that protect from rain. Due to their low need for water, they are a sustainable landscaping option. Cactariums also tend to host plants from other botanical families, native to the desert regions of the world. History A cactus garden is a garden for the cultivation and display with many types of cacti. Cacti, due to their unusual appearance for Europeans, attracted the attention of the first European colonizers of Americas and were brought to Europe as ornamental plants already in the 16th century. ...

Echinocereus Viereckii
''Echinocereus'' is a genus of ribbed, usually small to medium-sized, cylindrical shaped cacti, comprising about 70 species native to the southern United States and Mexico in very sunny, rocky places. Usually the flowers are large and the fruit edible. The name comes from the Ancient Greek ἐχῖνος (''echinos''), meaning "hedgehog", and the Latin ''cereus'' meaning "candle". They are sometimes known as hedgehog cacti, a term also used for the ''Pediocactus'' and ''Echinopsis''. Description The species of the genus Echinocereus grow solitary or branching with prostrate to erect shoots that are spherical to cylindrical. The roots are fibrous or bulbous. The plants reach heights of growth between 1 and 60 centimeters. On the tips of the 4 to 26 ribs, which are mostly clear and only rarely resolved into humps, are the areoles, from which differently shaped spines can arise. The small to large, funnel-shaped flowers arise at the top of an areole or break through the epidermis. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astrophytum Capricorne
''Astrophytum capricorne'', the goat's horn cactus, is a species of flowering plant in the cactus family Cactaceae, that is native to the Coahuila regions of Northern Mexico. Growing to tall by wide in a ball or oval shape, it is grey-green in colour with 7 to 9 prominent ribs, very long twisted spines and yellow flowers with a red centre in summer. The common name of goat's horn cactus corresponds to the species identifier ''capricorne'' (''capri'' meaning “goat” and ''corne'' meaning “horn”) referring to the curved spines that are said to resemble a goat's horns. This species is designated as of "least concern" by the IUCN as it is widely distributed in the Chihuahuan desert. Cultivation This species is grown, typically from seed, as an ornamental plant as it produces large, attractive yellow flowers with red central regions. Some cultivars bear white flecking on the plant body while others lack this feature. Though tolerant of cold temperatures, it must be grown in ...

Lithops
''Lithops'' is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words () 'stone' and () 'face', referring to the stone-like appearance of the plants. They avoid being eaten by blending in with surrounding rocks and are often known as pebble plants or living stones. The formation of the name from the Ancient Greek ''-ops'' means that even a single plant is called a Lithops. Description Individual ''Lithops'' plants consist of one or more pairs of bulbous, almost fused leaves opposite to each other and hardly any stem. The slit between the leaves contains the meristem and produces flowers and new leaves. The leaves of ''Lithops'' are mostly buried below the surface of the soil, with a partially or completely translucent top surface known as a leaf window which allows light to enter the interior of the leaves for photosynthesis. During winter a new leaf pair, or occa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echeveria
''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. Description Plants may be evergreen or deciduous. Flowers on short stalks (cymes) arise from compact rosettes of succulent fleshy, often brightly coloured leaves. Species are polycarpic, meaning that they may flower and set seed many times over the course of their lifetimes. Often numerous offsets are produced, and are commonly known as "hen and chicks", which can also refer to other genera, such as ''Sempervivum'', that are significantly different from ''Echeveria''. Many species of ''Echeveria'' serve important environmental roles, such as those of host plants for butterflies. For example, the butterfly ''Callophrys xami'' uses several species of ''Echeveria'', such as ''Echevelia gibbiflora'', for suitable host plants. Even more, these plants are integral to the oviposition process of ''C. xami'' and some other b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cultivars
A cultivar is a type of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and when Plant propagation, propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human genetic engineering, manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''#Formal definition, Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seedling
A seedling is a young sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves). The two classes of flowering plants (angiosperms) are distinguished by their numbers of seed leaves: monocotyledons (monocots) have one blade-shaped cotyledon, whereas dicotyledons (dicots) possess two round cotyledons. Gymnosperms are more varied. For example, pine seedlings have up to eight cotyledons. The seedlings of some flowering plants have no cotyledons at all. These are said to be acotyledons. The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule does not occur until the cotyledons have grown ab ...

Cutting
Cutting is the separation or opening of a physical object, into two or more portions, through the application of an acutely directed force. Implements commonly used for wikt:cut, cutting are the knife and saw, or in medicine and science the scalpel and microtome. However, any sufficiently sharp object is capable of cutting if it has a hardness sufficiently larger than the object being cut, and if it is applied with sufficient force. Even liquids can be used to cut things when applied with sufficient force (see water jet cutter). Cutting is a compression (physical), compressive and shearing (physics), shearing phenomenon, and occurs only when the total stress (physics), stress generated by the cutting implement exceeds the ultimate Strength of materials, strength of the material of the object being cut. The simplest applicable equation is: \text = or \tau=\frac The stress generated by a cutting implement is directly proportional to the force with which it is applied, and in ...
