Desert Globemallow

Sphaeralcea ambigua

A burst of spring color in cup-shaped flowers of apricot orange, pink, or white

Highlights

Imagine a burst of tiny apricot-colored teacups bringing all the buzz to your yard every spring. That’s what you get with desert globemallow (Sphaeralcea ambigua). In return, it asks for just a few things: full sun, rocky or sandy soil, and a gardener who forgets the hose. Spring is the big show, with flowers off and on through November. The plant reseeds, so one clump can become a whole patch. Seedlings sometimes bloom in a different color than their parent, which makes for a nice surprise! If the strip along your driveway has beaten every other plant, start here.

It’s the first guest at an empty party, and it brings bees.

Why globemallow matters

Bees are the headline here. Globemallow’s many flowers give a steady supply of pollen and nectar to honeybees and other insects, with special value to native bees. The common checkered skipper butterfly visits too.

It also feeds bigger visitors. Desert tortoises eat it, and it’s a top pick for tortoise gardens. Bighorn sheep and other grazing animals browse it. Hummingbirds, moths, and butterflies may visit as well. It’s also on a short list of top native plants for Sonoran Desert insects, birds, and pollinators.

Out in the desert it shows up early on burned or disturbed ground and can crowd out invasive weeds. It’s the first guest at an empty party, and it brings bees.

Globemallow through the seasons

Spring

This is the main show in warm deserts. Bowl-shaped apricot flowers open in clusters along the stems, and bloom is heaviest now. After a very wet winter, plants can shoot up to 5 feet tall, so leave them elbow room.

Summer

In the hottest time of year, flowers get sparse and patchy, but a good rain can set off another round. In cooler gardens, bloom comes later, from July through September. When the flowers fade, brown, globe-shaped seed capsules take over.

Fall

Flowers keep turning up through November, so bees still have something to visit. Fall is also the time to sow seed. Seedlings from your patch may bloom in colors that differ from their parents, so every year can bring a small surprise.

Winter

Seed sown in fall usually sprouts over winter and grows fast in spring, so the work happens before you see it. The plant is hardy to -10°F, so most cold snaps are no problem. In mild deserts, a few flowers can show up in any month when there’s enough moisture

Where globemallow shines in your yard

How to grow globemallow

Where to plant

Pick a spot with full sun and fast-draining soil, like the gravel edge of a driveway or a sunny bank. Rocky or sandy is just right. Choose with care, because you only get one shot. This plant hates being moved. Its roots can reach 3 feet to the side, and a damaged root can kill it.

When to plant

Plant in fall. Sow untreated seed about ¼ inch deep, walk away, and let winter do the work. Seeds sprout over the cooler months, and by spring you’ve got a head start. If you miss fall, early spring works too.

Spacing

Give each plant 2 to 3 feet, because a mature clump grows 2 to 3 feet wide. Leave a little extra if you can. It reseeds and spreads, so new plants will crowd in sooner than you expect.

Watering

Keep the soil surface damp while seedlings get started so it doesn’t crust over. After that, put the hose away and let the rain handle it. A little extra water means more flowers, but that’s a bonus, not a requirement.

Drought-tolerant Deer-resistant Host plant

What to plant with globemallow

All of these like full sun and dry, well-drained soil. Orange pairs well with yellow, white, and pink.

Where can I buy globemallow?

Buy it from a native plant nursery near you, and check the botanical name on the tag, because several globemallows look alike and are easy to mix up. Buy a plant you can set in its final spot the first time, since it doesn’t like being moved.

Potential challenges

Deer, rabbits, and other nibblers. Deer usually leave it alone, though deer resistant doesn’t mean deer proof. Rabbits rarely bother it in gardens, but jackrabbits do eat globemallow in the wild, and bighorn sheep browse it. If a few leaves go missing, don’t worry: it reseeds, and the patch fills back in on its own.

Spreading and reseeding. It reseeds and spreads by underground stems, so it can take over garden spaces. You’ll see it coming; pull the suckers you don’t want. Seedlings may bloom in a different color, so expect a few surprises.

Itchy leaves. Tiny hairs on the leaves can irritate eyes, which is how it got the nickname “sore eye poppy.” Keep your hands away from your face while you work around it

A short life. Individual plants don’t last long, but the patch keeps going by dropping seed.

A note on cultivars and relatives

Desert globemallow is usually apricot orange, but some plants have pink, lavender, or white flowers (sometimes called Parish mallow). Several globemallows are near twins, including Emory’s globemallow (S. emoryi) and caliche globemallow (S. laxa). Only a close look at the seeds under a microscope reliably separates desert globemallow from S. laxa, so check the botanical name on the tag.

FAQs

Is globe mallow invasive?

Desert globemallow is native to the desert Southwest, but it can reseed and spread enough to crowd out neighbors in a garden. Expect to pull suckers, and know it can turn weedy in some regions. Plant it where it has room to roam.

Where is the best place to plant a mallow plant?

Plant desert globemallow in full sun, in dry, well-drained rocky or sandy soil. The gravel edge of a driveway, a sunny roadside strip, or a rocky slope is its kind of place. Pick the spot with care, because it doesn’t like being moved.

Do hummingbirds like globe mallow?

Maybe, but hummingbird visits are less documented than bee visits. Bees are the sure bet, with native bees, honeybees, and butterflies all stopping by.

Does mallow grow back every year?

Yes, desert globemallow is a perennial, though each plant is fairly short-lived. It keeps the patch going by dropping seed, so the patch keeps filling in.

Will deer or rabbits eat desert globemallow?

Deer and rabbits rarely damage it, though jackrabbits do eat globemallow in the wild. Deer resistant doesn’t mean deer proof, but a nibble here and there won’t wipe out a plant that reseeds.

When does desert globemallow bloom?

It blooms mostly in spring in warm deserts and later in cooler gardens, with flowers on and off into fall. A good rain can set off another round of blooms.

How much water does desert globemallow need?

Globemallow needs very little water: once settled, natural rainfall can be enough. Extra water means more flowers though, so a little help is a bonus, not a rule.

Plant nerd fact

The sore eye plant

The Spanish name mal de ojo means “sore eye,” and the plant’s name in O’odham means the same thing. The star-shaped hairs on the leaves can irritate eyes, and they probably evolved to discourage grazers. It’s also called “sore eye poppy.” Oddly, the Shoshoni made an eyewash from globemallow, though it’s unclear which species they used. The Yavapai used the stems to make trays for drying saguaro fruit and slabs of pounded mescal.

If you’ve been staring at the gravel strip by your driveway, wondering what could possibly live there, this is your answer. Scatter seed in fall, and by spring you could have apricot flowers and a line of bees at the curb. Give it room, go easy on the hose, and let it fill in. Next year’s plants may pop up where you didn’t plan them, and some will bloom in a different color than their parents. If it wanders farther than you like, pull the suckers you don’t want.
