Bromeliads are a varied group of organisms, adapted to a number of climates. Foliage take different shapes, from needle thin to broad and flat, symmetrical to irregular, spiky and soft. The foliage, which usually grows in a rosette, is the most widely patterned and colored of any plant in the world. Leaf colors range from maroon, through shades of green, to gold. Varieties may have leaves with red, yellow, white and cream variegations. Others may be spotted with purple, red, or cream, while others have different colors on the tops and bottoms of the leaves.
