The plant produces vibrant, golden-yellow flowers that are daisy-like in appearance. The flowers are small, about 1 inch (2.5 cm) in diameter, and are arranged in clusters at the ends of the stems. Mexican Marigold blooms profusely from late summer through fall, attracting pollinators like bees and butterflies with its nectar-rich flowers.
One notable feature of Mexican Marigold is its strong fragrance. The leaves emit a pungent scent when crushed, which is often described as a combination of citrus and spice. This fragrance is believed to repel certain pests, making it a popular choice for natural pest control in gardens.
