Rosa 'Général Jacqueminot'
''Rosa'' 'Général Jacqueminot' (pronounced: zhay-nay RHAL zhock-mee-NOH), also called 'General Jack' or 'Jack Rose', is an early Hybrid Perpetual rose cultivar, developed by Roussel, an amateur from Meudon, and introduced by the gardener Rousselet in 1853. The flower was named in honor of Jean-François Jacqueminot (1787-1865), a French general of the Napoleonic Wars. Its parentage is unclear, but 'Gloire des Rosomanes' and 'Géant des Batailles' are considered probable ancestors. The large, double flowers are extremely fragrant. Their colour is clear red to deep pink, displaying darker purple hues as they age, The reverse is paler with occasional white streaking. The bloom form is globular and high-centered, with 24 to 30 broad petals with wavy edges, and an average diameter of . The flowers develop from pointed, bright scarlet-crimson buds and appear in small clusters of 2 to 3 on long stems in a spring and autumn flush and scattered blooms in between. The vigorous shrub ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rose
A rose is either a woody perennial flowering plant of the genus ''Rosa'' (), in the family Rosaceae (), or the flower it bears. There are over three hundred species and tens of thousands of cultivars. They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp prickles. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses. Etymology The name ''rose'' comes from ...

USDA Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

Phi Kappa Psi
Phi Kappa Psi (), commonly known as Phi Psi, is an American collegiate social fraternity that was founded by William Henry Letterman and Charles Page Thomas Moore in Widow Letterman's home on the campus of Jefferson College in Canonsburg, Pennsylvania on February 19, 1852. There are over 90 chapters and colonies at accredited four year colleges and universities throughout the United States. More than 179,000 men have been initiated into Phi Kappa Psi since its founding. Phi Kappa Psi and Phi Gamma Delta, both founded at the same college, form the Jefferson Duo. History In the winter of 1850, a typhoid fever epidemic hit Jefferson College in Canonsburg, Pennsylvania. Many students left school. Among those who remained were William Henry Letterman and Charles Page Thomas Moore. They chose to care for their classmates who were stricken with the contagious disease, and a strong bond was formed. In the following school year, Letterman and Moore decided to found a fraternity b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sport (botany)
In botany, a sport or bud sport, traditionally called ''lusus'', is a part of a plant that shows morphological differences from the rest of the plant. Sports may differ by foliage shape or color, flowers, fruit, or branch structure. The cause is generally thought to be a chance genetic mutation. Sports with desirable characteristics are often propagated vegetatively to form new cultivars A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture ... that retain the characteristics of the new morphology. Such selections are often prone to "reversion", meaning that part or all of the plant reverts to its original form. An example of a bud sport is the nectarine, at least some of which developed as a bud sport from peaches. Other common fruits resulting from a sport mutation are the red Anjou ...

Mildew
Mildew is a form of fungus. It is distinguished from its closely related counterpart, mould, largely by its colour: moulds appear in shades of black, blue, red, and green, whereas mildew is white. It appears as a thin, superficial growth consisting of minute hyphae ( fungal filaments) produced especially on living plants or organic matter such as wood, paper or leather. Both mould and mildew produce distinct offensive odours, and both have been identified as the cause of certain human ailments. In horticulture, mildew is either species of fungus in the order Erysiphales, or fungus-like organisms in the family '' Peronosporaceae''. It is also used more generally to mean mould growth. In Old English, mildew meant honeydew (a substance secreted by aphids on leaves, formerly thought to distill from the air like dew), and later came to mean mould or fungus. Mildew grows on damp cloth, leather, or on plants, and growing on leaves can damage the plant. Household varieties The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rust (fungus)
Rusts are plant diseases caused by pathogen In biology, a pathogen ( el, πάθος, "suffering", "passion" and , "producer of") in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a ger ...ic fungus, fungi of the order Pucciniales (previously known as Uredinales). An estimated 168 rust genera and approximately 7,000 species, more than half of which belong to the genus ''Puccinia'', are currently accepted. Rust fungi are highly specialized plant pathogens with several unique features. Taken as a group, rust fungi are diverse and affect many kinds of plants. However, each species has a very narrow range of hosts and cannot be transmitted to non-host plants. In addition, most rust fungi cannot be grown easily in pure culture. A single species of rust fungi may be able to infect two different plant hosts in different stages of its life cycle, and may produce up to five Morpholog ...

Prickle (botany)
In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called ''spinose teeth'' or ''spinose apical processes''), are hard, rigid extensions or modifications of leaves, roots, stems or buds with sharp, stiff ends, and generally serve the same function: physically deterring animals from eating the plant material. Description In common language the terms are used more or less interchangeably, but in botanical terms, thorns are derived shoots (so that they may or may not be branched, they may or may not have leaves, and they may or may not arise from a bud),Simpson, M.

Hybrid Perpetual
Garden roses are predominantly hybrid roses that are grown as ornamental plants in private or public gardens. They are one of the most popular and widely cultivated groups of flowering plants, especially in temperate climates. An enormous number of garden cultivars have been produced, especially over the last two centuries, though roses have been known in the garden for millennia beforehand. While most garden roses are grown for their flowers, often in dedicated rose gardens, some are also valued for other reasons, such as having ornamental fruit, providing ground cover, or for hedging. The cultivars are classified in a number of different and overlapping ways, generally without much reference to strict botanical principles. Taking overall size and shape, the most common type is the bush rose, a rounded plant from 2 foot up to about 7 foot tall, above which height roses generally fall into the "'climbing and rambling'" class, the latter spreading wider; support is needed for th ...

Petal
Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as '' Aloe'' and '' Tulipa''. Conversely, genera such as ''Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Since they include Liliales, an alte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
