Often referred to as Lemmon’s Marigold, Copper Canyon Daisy, or Mexican Bush Daisy, Tagetes lemmonii, the Mexican Marigold, is a striking plant that brings a burst of golden color to your garden, especially when many other blooms have faded. While you can choose any of its common names, there’s a certain appeal in calling it Tagetes lemmonii, pronounced TA-je-tees lem-MO-ni-I, as it rolls off the tongue with a botanical elegance.

My first encounter with this gem was at a local nursery specializing in native and Mediterranean plants. Starting from a small 3-inch pot, it astonishingly transformed into a lush, four-foot-tall bush, generously adorned with vibrant yellow-gold flowers right when a splash of color is most welcome in mid-November. This late-season bloomer is a true gift for extending the garden’s beauty into the cooler months.

Bringing cuttings indoors, I was immediately met with its intensely pungent fragrance – some might even describe it as a bit stinky! It’s perhaps best to appreciate its unique scent in the garden, where it can beautifully complement the aromas of Autumn sage, Asters, and Pineapple sage. This potent fragrance is one of its distinctive characteristics.

Initially potted on the patio, I learned quickly that Tagetes lemmonii can be quite demanding of water when container-grown, especially during the heat of August. Daily watering was essential to prevent drooping. Even a slight brush against the leaves would release its startlingly strong scent. Despite enduring a snowfall, these resilient plants bounced right back, their sturdy stems proving their hardiness.

The Mexican Marigold planted directly in the salvia bed, receiving less frequent watering, thrived equally well and bloomed in November. This adaptability makes it versatile for different garden spots. It’s a true sun-loving plant, ideal for bringing brightness to overcast autumn days.
For optimal growth, plant Mexican Marigold in a sunny or partially shaded location with well-drained soil, similar to natural slopes. While drought-tolerant once established, it flourishes with moderate irrigation. Overwatering or insufficient light can lead to leggy growth and reduced blooming. It is frost-tender to hard frosts but demonstrates remarkable resilience, recovering quickly and tolerating temperatures down to at least 18°F, typical in regions around 3000′ elevation. Embrace the vibrant Mexican Marigold for a sunny disposition in your fall garden.
