Lilies can be divided into many groups, but the most widely known are Asiatic and Oriental hybrids. The flowers come in nodding, upright and trumpet forms. Asiatic hybrids are easy to grow but are unscented. On the other hand, Oriental hybrids are bold, colourful, and highly scented but require acidic soil to grow.
They are available in a dazzling array of colours, from white and pink to red, yellow, and orange and the petals often have markings like spots or brush strokes.
