They arguably captivate the human imagination more than any other plant species on the planet. With exotic names like the Butterfly, Sharry Baby, Dancing Lady, Oncidium Twinkles, Ghost and Slipper Orchid, orchids are available in a stunning range of colours with fragrances that are unrivalled in nature. The exquisite flower is ranked the second most popular potted plant in the United States and could soon replace the Poinsettia as number one. - Chris Loft
