Exploring Florida’s Natives: Marigold

Marigolds (Tagetes spp.) have long been beloved for their rich coloring and ability to suppress plant – parasitic nematodes. This is true, however, simply planting marigolds in your garden or landscape, or intercropping, will not reduce nematode populations. Let’s explore the origins and growing conditions of the marigold.

Origins of the Marigold

Marigolds are native to the Americas, with species originating from both North and South America. In their natural habitats, they grow in open, sunny fields and meadows. Read more about the cultural significance of marigolds here.

Growing Conditions and Characteristics

Marigolds thrive in USDA Hardiness Zones 2 to 11, making them an excellent choice for the diverse climates of Central Florida. They typically reach a height of 1 – 3 feet tall, depending on the variety, and have a spread of 6 to 12 inches. This annual plant is a great option for the summer season and prefers well-drained soil and requires a minimum of 6 hours of full sun. For best results, place them a foot apart and plant them in large numbers.

These hardy flowers are known to withstand the heat, making them well suited to Florida’s climate. Marigolds are generally low maintenance, requiring only moderate watering and occasional deadheading to prolong their blooming period. They can be used in several garden settings, including flower beds, borders, and container gardens. Their bright yellow, orange, or golden flowers can add a pop of color and attract pollinators and beneficial insects to your garden. Learn more about marigolds here.

Why Plant Native Species?

While native and non-invasive exotic plants can enhance local ecosystems, invasive exotic species pose a threat to native flora and disrupt ecological balance. In Florida, invasive species like the Mexican petunia and Brazilian peppertree jeopardize native habitats, making it crucial to select appropriate plants for your landscape. Choosing native plants like the marigold supports Central Florida’s local ecology by providing food and habitat for native wildlife while requiring minimal maintenance.
