About Mexican marigold
Tagetes lemmonii, commonly known as Mexican Marigold or Lemmon's Marigold, is a fragrant perennial shrub from the Asteraceae family, valued for its deeply lobed foliage and vibrant yellow flowers that bloom from late summer into winter. Its distinctive citrusy and pungent aroma makes it ideal for fragrance gardens, mixed borders, or as an accent plant near pathways. It can grow up to 1.5 meters (5 feet) tall and wide, forming a dense, rounded shrub.
Native range
Northwestern Mexico and the southwestern United States (Arizona and New Mexico)
Care tips
It requires full sun for optimal flowering and compact growth, though it can tolerate some partial shade in very hot climates. Watering should be moderate once established, allowing the substrate to dry out slightly between waterings; it is quite drought-tolerant. It prefers well-drained, fertile soils, and a common mistake is overwatering, which can lead to root rot. Light pruning after flowering helps maintain its shape and encourages new growth.
