Description

The Desert marigold is a small and colorful herbaceous perennial with a low and spreading habit, growing 12-18 in. tall, 24-30 in. across. Silvery gray-green foliage is comprised of small deeply lobed leaves that are covered with fine woolly hairs. Bright and colorful daisy-like deep yellow flowers grow on tall stems and occur from late winter and intermittently through summer.

Desert marigold is native to arid regions of northern Mexico and the southwest United States where it is noted in seasonal wildflower displays. It commonly grows along washes, roadsides and on rocky slopes, and does best where moisture from seasonal rainfall collects. In Inland Empire gardens it is a colorful flowering accent plant that is used southwestern style gardens along walkways, around rocks and in wildflower plantings. It is adapted to full sun, heat and aridity, and grows best for 3-5 years.

Water Needs

The Desert marigold easily adapts to warm and sunny climate conditions of the Inland Empire. Established plants grow well with very little and infrequent summer water. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water; more supplemental water commonly results in a longer flowering season and larger sizes.
