The Bromeliaceae (the bromeliads) is a family of monocot flowering plants of 75 genera and around 3590 known species native mainly to the tropical Americas, with a few species found in the American subtropics and one in tropical west Africa, Pitcairnia feliciana. Bromeliads are plants that are adapted to various climates. Foliage takes different shapes, from needle-thin to broad and flat, symmetrical to irregular, spiky to soft. The foliage, which usually grows in a rosette, is widely patterned and colored. Leaf colors range from maroon, through shades of green, to gold. Varieties may have leaves with red, yellow, white and cream variations. Others may be spotted with purple, red, or cream, while others have different colors on the tops and botttoms, and species Tillandsia cyanea have a fragrance resembling that of clove spice. The pineapple (Ananas comosus) is a tropical plant with an edible fruit and the most economically significant plant in the family Bromeliaceae.
