By Amy Deemer ; Updated September 21, 2017

Annuals are flowers that complete their life cycle in one year. Sun-loving annuals are among the easiest plants gardeners can grow. They come in a wide range of colors and are used in flower beds, containers and window boxes, or as a garden border. Annuals produce a beautiful variety of cutting flowers as well. Growing sun-loving annuals is a pleasurable experience for both experienced and novice gardeners.

These plants do best in fertile, moist, but well-drained, soil with full sun exposure; although, they can tolerate some shade. Water plants regularly, especially in drier climates. Cockscomb grow to be about 36 inches tall. They have red, pink, yellow, cream and orange flowers. Cockscomb are prone to spider mites and leaf spots.
