Description

The Indian mallow is native to the dry foothill slopes and desert washes of California and Arizona where it grows with variable amounts of winter rainfall and long periods of drought. Its pale gray-green foliage helps reflect hot sun and reduce moisture stress. It commonly grows into a mounding shrub and can eventually reach 5-8 ft. tall and 4-5 ft. wide. Bright lemon-yellow flowers occur in late spring and can occur intermittently throughout the year. Seeds from these plants easily germinate in ornamental gardens.

Indian mallow is widely adapted to garden and landscape conditions throughout the Inland Empire. It thrives in full sun and with low amounts of supplemental water in the summer. As a California native, it has proven to be one of the easiest to grow and is highly tolerant of summer water. Plants receiving more water will grow faster and larger; it responds well to pruning in late fall through winter to manage its size. It combines well with other plants of the Southwest and many California native perennial species.

Water Needs

The Indian mallow is highly adaptable to varying moisture and irrigation practices in ornamental gardens. 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 growing season and larger sizes.
