The plants in the following three groups have been separated and grouped because of the interesting colour effects of the foliage. The most important factor in selecting plants for the autumn colouration of their foliage is to select material which will provide a succession of colour from early fall to late fall. The colours produced by the foliage of the different types are indicated after each type.
