How to identify African marigold (Tagetes erecta)
African marigold, also known as Flower of the dead, Mexican marigold
African marigold is characterized by its vibrant, large flowerheads that demand attention in any garden setting. This robust herbaceous annual typically grows vertically with a sturdy stature. Its stems, which can reach heights of up to 10 to 18 inches (25 to 46 cm), often require staking to support the considerable weight of the blossoms. The blooms exhibit a generous size, ranging from 2 to 3 inches (5 to 7.6 cm) in diameter, showcasing a range of warm colors that brighten outdoor spaces through the summer months.
