A native of Mexico, marigolds have been grown in gardens throughout the world for hundreds of years. Today, they are one of the most popular bedding plants in the United States.
Marigolds are easy to grow, bloom reliably all summer, and have few insect and disease problems.
There are numerous marigold varieties available to home gardeners. Many of the commonly grown marigolds are varieties of African and French marigolds. Less known are the triploid hybrids and the signet marigolds. Flowers may measure up to 5 inches across. Plant height varies from 10 to 36 inches.
