Sphaeralcea ambigua (Desert Mallow)
Desert Globemallow, Apricot Globe-Mallow, Desert Mallow, Globe Mallow, Apricot Mallow
Sphaeralcea ambigua (Desert Mallow) is an attractive multi-branched perennial shrub boasting a profusion of brilliant orange-red, cup-shaped flowers, 1 in. across (2.5 cm), in spectacular clusters along 2-3 ft. upright stems (60-90 cm). This is, however, quite a variable species, and the flowers may also be pink, lavender, or even white. Blooming profusely in spring, summer, and fall (depending on the geographic area), the flowers provide a rich source of pollen and nectar to honey bees and butterflies. The small, silvery green, three-lobed leaves, 4 in. long (10 cm), are crinkled and quite fuzzy with white hairs on both sides. Desert Mallow is relatively short-lived but delightfully self-seeds, keeping its presence in the garden. An effortless plant in the garden, it is heat and drought-tolerant and usually pest and disease free. It cannot withstand wet winters and is best adapted to desert climates. Perfect for water-wise borders and rock gardens.
- Grows up to 3-4 ft. tall (90-120 cm) and 2-3 ft. wide (60-90 cm).
- Thrives in full sun in sharply-drained, gravel-rich soil. Water maximum once per month in summer after the plant is established. Drought tolerant.
- It is a great candidate for beds and borders, cottage gardens, gravel gardens, or Mediterranean gardens.
- No serious pest or disease issues. Keep an eye out for hollyhock rust.
- Cut back after flowering to rejuvenate the plant.
- Propagate by seed (no treatment).
- Native to California, Nevada, Utah, Arizona, and Mexico.
