You may find desert marigold blooming at almost any time of the year. Its large yellow daisies and almost white foliage make a cheerful addition to any garden and look great near cactus and other succulents. It is a short-lived native perennial that will reseed regularly. Transplant seedlings in fall if you want to spread them around.
Give desert marigold good drainage and full sun. It can survive on natural rainfall. Help it out in the driest years by providing some gravel mulch, by planting it near rocks where the roots can enjoy the cooler, moister soil under the rock, or by getting out your watering can. Faded flowers can be removed any time. If it begins looking ratty, cut off all the upper foliage, leaving about 3 inches of fresh leaves.
Wildlife value: attracts insects, including pollinators.
