Globe Mallow: A Resilient Desert Beauty for Gardens

Globe mallow (Sphaeralcea ambigua) is a stunning perennial that feels equally at home in an English-style cottage garden or along a rugged desert roadside. Like many native desert perennials, its delicate appearance is deceiving—this is one remarkably tough plant that thrives in harsh conditions while adding vibrant color to the landscape.

Distinguishing Traits

At first glance, globe mallow appears rather unassuming with its gray-green lobed leaves. But once it blooms, it transforms into a landscape star. Flowers resembling small hollyhocks appear in spring, covering the plant in color.

The delightful surprise of globe mallow is that you often can't predict the flower color of a particular plant until it blooms. Most produce orange flowers, but red, rose, pink, and white forms also exist.

Ensuring Your Desired Flower Color

• Purchase plants from a nursery when they are already flowering.
• Take a cutting from a globe mallow with the flower color you prefer.
• For reliable red flowers, seek out the cultivar 'Louis Hamilton'.

If you enjoy surprises, simply plant a globe mallow and let it reveal its color when it blooms.

Landscape Uses

The delicate, hollyhock-like flowers make globe mallow an excellent addition to perennial beds for a cottage garden look. It also works well as a foundation planting, around swimming pools, and in containers.

Pair it with other native desert perennials for a cohesive, low-water landscape:

• Blackfoot daisy (Melampodium leucanthum)
• Desert marigold (Baileya multiradiata)
• Goodding's verbena (Glandularia gooddingii)
• Parry's penstemon (Penstemon parryi)

For striking texture and color contrast, combine globe mallow with dark green succulents like cow's horn agave (Agave bovicornuta).

Because globe mallow grows readily from seed, it's also valuable for revegetating bare areas.

Planting and Care Notes

This attractive perennial has few requirements. Plant in well-drained soil in full sun. For best appearance, water every other week in summer and once a month in winter (if no rain).

Maintenance is minimal: simply shear the plant back to about 1 foot after flowering finishes to stimulate another flush of blooms.
