Discovering the Desert Globemallow

Sphaeralcea ambigua, a member of the Malvaceae (mallow) family, is a captivating subshrub, exhibiting qualities of both a shrub and a perennial flower. Typically reaching a height and width of about three feet, it forms a pleasing, rounded shape. Its leaves, a soft, grayish-green, vary in shape from lance-like to triangular, depending on the specific plant. However, the true stars of the show are its flowers. These charming, bowl-shaped blooms, most commonly a vibrant apricot-orange, also appear in shades of coral and even pink, as seen in the ‘Papago Pink’ cultivar. These cheerful blossoms grace the desert landscape from spring to fall, providing a welcome splash of color.

Where the Globemallow Calls Home

A true Southwestern native, Sphaeralcea ambigua flourishes in the arid landscapes of the southwestern United States and northwestern Mexico. Deserts, dry washes, and rocky hillsides are its preferred habitats. Remarkably adapted to harsh conditions, it tolerates alkaline soil, intense heat, and prolonged dry spells. Its resilience even extends to USDA Zone 7, suggesting it can withstand light frosts.

Cultivating Your Own Desert Globemallow

Introducing this low-maintenance beauty to your garden is surprisingly simple.

Starting Your Globemallow: Begin your globemallow journey from either seeds or cuttings, both of which are relatively straightforward methods. Spring is generally considered the best time for propagation.
Planting Location: Select a sunny spot with well-drained soil. These plants aren’t picky, tolerating a range of soil types from sandy to clay.
Watering Wisdom: Once established, Sphaeralcea ambigua requires minimal watering. Water deeply but infrequently, allowing the soil to dry out between waterings. This encourages deep root growth and mimics its natural desert environment.
Fertilizing Needs: Supplemental feeding is usually unnecessary. Too much fertilizer can actually hinder flowering.
Pruning Practices: Light pruning to remove dead or damaged branches is typically sufficient. A fall pruning can encourage bushier growth in the following spring.
Pest and Disease Management: Desert globemallow exhibits remarkable resistance to pests. The primary concern is root rot, which can occur in overly wet conditions. Regularly inspect your plant for any signs of pests or diseases.
