The delicate beauty of the yellow daisy-like flowers belies the ability of desert marigold to thrive in inhospitable conditions. Rocky soil, reflected sun and little water don’t bother this tough perennial once it is established.

During the warm season, its sunny flowers can be seen along roadsides, in wildflower gardens and alongside cacti in both residential and commercial landscapes.

Desert marigold is short lived, but it does reseed easily, ensuring new plants. Bright yellow flowers are borne above foliage covered in tiny, white hairs, giving it a gray-green appearance.

While desert marigold can often survive on natural rainfall once established, it does appreciate supplemental water once or twice a month when rainfall is absent. Avoid overwatering, which can kill it. Noelle Johnson Landscape Consulting How to use it. Because desert marigold reseeds readily, it is more suitable for landscapes with a natural desert theme or wildflower gardens than formal landscapes, where it can be viewed more as a weed.

Desert marigold is a popular component of many wildflower seed mixes, so be sure to include it in your favorite wild seed mixture when sowing seeds in the fall.

Pair it with blackfoot daisy (Melampodium leucanthum), firecracker penstemon (Penstemon eatonii), globe mallow (Sphaeralcea ambigua) and verbena (Glandularia species) for an informal desert flower garden.

You can also use it to add color and soft texture in landscapes filled with cacti such as cholla, ocotillo and Santa-Rita prickly pear.

When the flowers start to fade or the foliage becomes dry and straggly, shear desert marigold to 6 inches to rejuvenate it. Noelle Johnson Landscape Consulting Planting notes. While desert marigold often grows from seed in recently disturbed areas such as roadsides, it can also be transplanted from containers.

Select an area that receives full sun and has well-drained soil. Be careful to keep desert marigold away from areas that are frequently watered, or it will become straggly and won’t produce flowers.

If you plant it from seed, water it every few days until the seed has germinated. Thereafter water twice a week for the first month and then once a week until it can survive on its own — typically three months after planting.

Newly planted transplants require supplemental water until becoming established in the new location. Water twice a week for the first month, then taper off to once a week and then gradually to once a month.
