Cosmos Overview
Cosmos is a genus of over 40 annual and tuberous perennial or annual species originally from the scrublands and meadows of the Southern USA and Central America. Cosmos is very popular with gardeners and is grown and cultivated extensively for its large, showy, daisy-like blooms that are borne on long stalks in summer. The flowers can be saucer, bowl or cup-shaped and of a wide variety of colours. The leaves, which always appear as opposite pairs, are of different shapes, depending on species or cultivar. Easy to grow, cosmos are most often seen spreading in drifts across sunny flower beds and borders. They like moderately fertile, moist, well-drained soil.
