The President's Garden

Prior to 1902, there were extensive stables, housing horses and coaches, located on the grounds of the present-day Oval Office, Cabinet Room, and Rose Garden. During the 1902 Roosevelt renovation, First Lady Edith Rooseelt insisted on a proper colonial garden to help replace the conservatory rose house that had stood here. The Rose Garden is based on a traditional 18th century American garden. The current design of the garden dates to the Kennedy Administration. President and Mrs. Kennedy were interested in having horticultural features that followed the traditions of Presidents Washington and Jefferson. The West Garden has been called the Rose Garden since 1913 when Mrs. Ellen Wilson replaced the existing colonial garden with a formal rose garden. The Rose Garden features a rectangular grass panel surrounded by flower beds and crabapple trees. The garden is steps from the Oval Office and is the stage for numerous receptions, bill signings and media events annually. More than 30 different types of tulips and grape hyacinth are planted in the flower beds that are framed and crisscrossed with boxwood. Lavender cotton, planted in the shape of diamonds, surrounds the crabapple trees. The Rose Garden was once a formal flower garden, but it was eventually converted to a broad lawn surrounded by flower and shrub plantings so that presidents could hold press conferences out in the sunny, open area with the West Wing colonnade as a backdrop.

Ornamental plants

Main article: Garden roses The majority of ornamental roses are hybrids that were bred for their flowers. A few, mostly species roses are grown for attractive or scented foliage (such as Rosa glauca and Rosa rubiginosa), ornamental thorns (such as Rosa sericea) or for their showy fruit (such as Rosa moyesii). Hybrid Tea cultivar 'Mrs. Herbert Stevens' Ornamental roses have been cultivated for millennia, with the earliest known cultivation known to date from at least 500 BC in Mediterranean countries, Persia, and China.[5] Many thousands of rose hybrids and cultivars have been bred and selected for garden use as flowering plants. Most are double-flowered with many or all of the stamens having mutated into additional petals. In the early 19th century the Empress Josephine of France patronized the development of rose breeding at her gardens at Malmaison. As long ago as 1840 a collection numbering over one thousand different cultivars, varieties and species was possible when a rosarium was planted by Loddiges nursery for Abney Park Cemetery, an early Victorian garden cemetery and arboretum in England. A few species and hybrids are grown for non-floral ornamental use. Among these are those grown for prominent hips, such as the flagon shaped hips of Rosa moyesii. Sometimes even the thorns can be treated as an attraction or curiosity, such as with Rosa sericea. Cut flowers Bouquet of pink roses Roses are a popular crop for both domestic and commercial cut flowers. Generally they are harvested and cut when in bud, and held in refrigerated conditions until ready for display at their point of sale. In temperate climates, cut roses are often grown in glasshouses, and in warmer countries they may also be grown under cover in order to ensure that the flowers are not damaged by weather and that pests and disease control can be carried out effectively. Significant quantities are grown in some tropical countries, and these are shipped by air to markets across the world.[6] Perfume Main articles: Rose oil, Attar of roses, and Rose water Rose perfumes are made from attar of roses or rose oil, which is a mixture of volatile essential oils obtained by steam distilling the crushed petals of roses. An associated product is rose water which is used for cooking, cosmetics, medicine and in religious practices. The production technique originated in Persia then spread through Arabia and India, and more recently into eastern Europe. In Bulgaria, Iran and Germany, damask roses (Rosa damascena 'Trigintipetala') are used. In other parts of the world Rosa centifolia is commonly used. The oil is transparent pale yellow or yellow-grey in colour. 'Rose Absolute' is solvent-extracted with hexane and produces a darker oil, dark yellow to orange in colour. The weight of oil extracted is about one three-thousandth to one six-thousandth of the weight of the flowers; for example, about two thousand flowers are required to produce one gram of oil. Geraniol (C10H18O) The main constituents of attar of roses are the fragrant alcohols geraniol and l-citronellol; and rose camphor, an odourless paraffin. β-Damascenone is also a significant contributor to the scent. Rose water, made as a byproduct of rose oil production, is widely used in Asian and Middle Eastern cuisine. In France there is much use of rose syrup, most commonly made from an extract of rose petals. In the United States, this French rose syrup is used to make rose scones and marshmallows. Rose hips The rose hip, the fruit of some species, is used as a minor source of Vitamin C. Rosa canina hips Rose hips are occasionally made into jam, jelly, and marmalade, or are brewed for tea, primarily for their high vitamin C content. They are also pressed and filtered to make rose hip syrup. Rose hips are also used to produce Rose hip seed oil, which is used in skin products and some makeup products. Medicine The fruits of many species have significant levels of vitamins and have been used as a food supplement (see previous section). Many roses have been used in herbal and folk medicines. Rosa chinensis has long been used in Chinese traditional medicine. This and other species have been used for stomach problems, and are being investigated for controlling cancer growth.[7] Culture Art Roses are a favored subject in art and therefore used in various artistic disciplines. They appear in portraits, illustrations, on stamps, as ornaments or as architectural elements. The Luxembourg born Belgian artist and botanist Pierre-Joseph Redouté is known for his detailed watercolours of flowers, particularly roses. Renoir's painting of cabbage roses, Roses in a vase Henri Fantin-Latour was also a prolific painter of still life, particularly flowers including roses. The Rose 'Fantin-Latour' was named after the artist. Other impressionists including Claude Monet, Paul Cézanne and Pierre-Auguste Renoir have paintings of roses among their works.
