A rose is a woody perennial of the genus Rosa, within the family Rosaceae. There are over 100 species and 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. 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 nativeto Europe, North America, and northwest Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. 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.
Believe it or not, orchids make up the planet's largest group of blooming flowers. They grow in every continent but one (sadly, you won't find them in icy Antarctica), and come in hundreds of shapes and sizes. Also, about 99% of orchids today are within reach and available for cultivation, while 1% of tropical varieties still grow in virtually inaccessible habitats and have only been seen a handful of times.
