marigold

Marigold is a common name for several flowering plants in the Asteraceae family, most notably the genera Tagetes and Calendula. In horticulture, Tagetes erecta (African marigold) and Tagetes patula (French marigold) are the forms most often referred to as marigolds, while Calendula officinalis is usually called pot marigold or calendula.

Marigolds are annuals or short‑lived perennials with showy composite flowers. Colors range from pale yellow to deep orange, and some cultivars display bi‑color blooms. The flower heads consist of ray florets surrounding a central disk; leaves are often aromatic and can be finely divided in Tagetes species.

Growing requirements vary by species, but most marigolds prefer full sun and well‑drained soil. They are typically tolerant of heat and drought, bloom from late spring to autumn, and benefit from deadheading. Plant Tagetes from seed in spring; calendula is often grown from seed sown in early spring or started indoors.

Uses include ornamental bedding and borders. Calendula petals are edible and used as a garnish or in herbal preparations; calendula and related extracts are used in cosmetics and skin care. Tagetes are valued in companion planting for pest deterrence, though they are not generally eaten. Culturally, marigolds hold symbolic significance in several traditions, including Día de los Muertos in parts of Latin America. Some individuals may experience skin irritation from contact with certain marigold varieties; as with many ornamental plants, keep pets away from ingestion unless advised otherwise.
