Sphaeralcea ambigua-Globe Mallow

Celebrate spring with a rainbow of colors by establishing a population of Globe mallow in your garden! This native perennial has a relaxed, sprawling form that mixes well with other desert plants. Although a light orange flower color is the most common, other color selections have been made from wild populations, ranging from white to lavender to pink to red. So far, one cutting-grown clone is available, Louis Hamilton™, which has large watermelon-red blossoms. Our blocks of regular Sphaeralcea ambigua contain a mix of several lovely flower colors. Globe mallow starts to look rangy after flowering, and should be cut back to about six inches tall in the early fall. Soon after, it will generate many fresh herbaceous stems from the woody base, quickly reaching a height and width of three feet in one growing season. The small, grayish-green, three lobed leaves are covered with tiny hairs that can be quite irritating. Be sure to wear gloves and long sleeves when pruning this plant! Globe mallow is hardy to 0º F, and is extremely drought tolerant. It performs best in full sun and reflected heat exposures. USDA Zone 7.
