Crocus, a genus of plants belonging to the iris family. The flowers look as if they grow directly from the ground. Their six segments may be white, lavender, lilac, rose-purple, or yellow. Some varieties are striped, spotted, or tinged with several colors. Crocuses grow from bulblike corms (underground stems) that multiply, producing more crocus plants. A food flavoring is obtained from the dried stigmas (flower parts that receive pollen) of the saffron, a European crocus. The common crocus, which reaches a height of about five inches (13 cm), is one of the first flowers to bloom in the spring.
Crocuses belong to the family Iridaceae. The common crocus is Crocus vernus .The cloth of gold crocus blooms in the spring and has a bright orange-yellow flower.
