Additional comments: This is a great high desert native xeriscape accent perennial shrub that struggles a bit in low desert locations becase of the intense heat. Mount Lemon marigold is named after John G. Lemmon (1832-1908) who first collected this plant for cultivation in 1882 from the Huachuca Mountains in Cochise County in Arizona. Mount Lemon marigold is often confused with Tagetes lucida (Mexican tarragon).
