The Palmer’s 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 approximately 4 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.  Flowers are cup-shaped (5 petals), approximately one inch in size. It produces a small fruit which is round, capsular, multi-parted and covered with silky fine hair similar to foliage. Branches and stems are also hairy with a red-brown coloring to the twigs. Bark ranges from green to brown. It is widely adapted to garden and landscape conditions. It thrives in full sun and with low amounts of supplemental water in the summer. As a Southwestern 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 other Arizona natives as well.
