Marigolds (Tagetes spp.) are popular, easy-to-grow annuals known for vibrant orange, yellow, and red, pom-pom-like blooms. They thrive in full sun, well-draining soil, and hot, dry conditions, making them ideal for summer gardens, borders, and containers. Renowned for their pungent, pest-repelling scent, they act as companion plants that deter insects, including nematodes, while attracting pollinators.
