Desert Marigold

Growing Desert Marigold

About as drought-proof as a flowering plant gets, reseeding across gravel and decomposed granite. Shear it back after a flush to keep it tidy.

Where it belongs

Desert marigold is native to the Southwest, growing in the Sonoran and Chihuahuan deserts on gravel flats, roadsides, washes, and decomposed granite slopes, often in ground that looks incapable of supporting anything.

It is not related to garden marigolds, which are Mexican and Central American tagetes. The shared name is a coincidence of appearance.

The silver-white foliage is dense wool, and it works the way desert plant hair usually does: it reflects light and slows water loss from the leaf surface. That is a good part of why the plant tolerates conditions that kill ordinary perennials.

Growing it

Full sun, dry soil, in sand or rocky ground, zones 7 to 11. Twelve to eighteen inches.

The failure mode is water. Irrigation, rich soil, and mulch all shorten its life or kill it outright. Plant it in gravel, in unamended desert soil, in the part of the yard the sprinklers do not reach.

It is short-lived, functioning as a perennial in good conditions and as a reseeding annual otherwise, and it maintains itself by seeding into open ground. Leave bare gravel around it rather than mulching, or there will be no next generation.

Bloom is close to continuous where winters are mild, running from March into October and picking up after any decent rain. Shearing the plant back after a flush produces fresh growth and another round.

It is easiest from seed sown directly in fall.

What it feeds

The flower is a flat open daisy with an accessible center, which serves a broad range of insects rather than a specialist few.

Native bees are the main visitors, including small desert species active in the brief windows when conditions allow. Butterflies take nectar. Because the bloom season is so long, it feeds insects across periods when most desert plants are dormant and waiting for rain.

Small birds take the seed.

Living with it

Deer and rabbits mostly leave it alone. The plant is toxic to sheep and is avoided by grazing animals generally.

Its main use in a garden is as a filler and self-sowing matrix between structural plants such as agave, apache plume, or flame acanthus, where it supplies color in the gaps without competing for water.

Shear spent growth, leave the ground open for seedlings, and otherwise do nothing.

It’s deer-resistant, drought-tolerant, long-blooming, and showy.
