Mount Lemmon Marigold is an evergreen, perennial shrub that reaches about 3 feet in height with a spread of up to 6 feet. Because T. lemmonii is found in abundance near Mt. Lemmon in the Santa Catalina Mountains east of Tucson, many people assume it was named for that area. Actually it was named after John Gill Lemmon and his wife Sara, who discovered it growing in southeastern Arizona in the late 1800s. In Phoenix, this plant blooms from late winter through early fall.
