Description

Orange Globe Mallow (Sphaeralcea munroana) is a welcome sight in midsummer when the heat has driven most other flowers out of bloom. Sphaeralcea's long wands of orange flowers resemble miniature hollyhocks. A deep-rooted wildflower native to the western U.S., Orange Globe Mallow is not the least bit picky about its soil and thrives in heavy clay. Cut last year's stems back to ground level each spring for best appearance. Plant amongst Callirhoe, another clay lover, for a great summer color combination. 36-42" tall x 24" wide (seed propagated).

Flat of 18 plants will cover 36 square feet when planted together

Planting & Care

Sphaeralcea munroana (Orange Globe Mallow) - native to arid areas of the Great Basin in western North America. Very resistant to browsing deer and rabbits.

Preferred growing conditions

  • Plant in most soil types, including dry clay. Position in a full sun location.
  • Mulch with gravel.
  • Water regularly the first growing season to establish the plant. Thereafter, only occasional deep watering is needed when conditions are dry in the heat of summer.
  • Deadheading will not extend flowering. But, Sphaeralcea likes to re-seed itself, so deadheading will reduce unwanted seedling volunteers.
  • Fertilize lightly in the fall with Yum Yum

Special comments

  • Leave standing over the winter. Cut back to just above ground level in mid-spring. Pinch the tips of new stem growth to thicken the plant with more stems and flowers later in the growing season.
  • Plants will sometimes sucker and spread too widely for their space. Dig suckers in early to mid-spring and discard.
  • Some people are sensitive to minute, prickly hairs on stems and leaves; if so, use gloves when working with these plants.

Reviews

very zeric

"bought one of these several years ago. The original plant did not survive but a few seedlings did. I now have many of these in my dry rock garden, never watered after the first year. This plant is a vigorous seeder and takes a lot of space when mature. Seedlings can be transplanted but are difficult to establish. It absolutely does not need water after establishment. In our 16 inch per year climate it thrives. Don't water these truly zeric plants and they'll look better and live longer."

The specimen that arrived was

"The specimen that arrived was healthy and with stood the transfer from pot to the ground here in the southwest desert. It seems to be thriving and has grown a couple of inches since planting two weeks ago."

Great plant for truly dry, tough conditions

"I have these planted on a steep hill that faces south and is pounded with full sun and no shade at all in hot Utah summers. High winds too. The hill is pure sand and rocks. . . I would barely even call it "soil" and there is zero irrigation back there. I do hit these with a hose about once a week in the summer the first year to establish. Fantastic plants for a western garden if you truly have lots of sun and low fertility, dry soil. Will live where most others will not. However, when I tried these in my front yard where we have clay, they initially did nicely but did not come back. . . they grow much faster and seem happier in the windy, hot, dry hill of sand and rocks. Long flowering season and it's nice to have some orange, since for some reason it seems that so many deep-rooted high desert plants are purple. I have these planted next to Russian Sage and Wild 4 O'Clock that also do nicely on the dry, rocky hill, and the contrast of orange and purple is lovely. However, I took these photos in April when the Globe Mallow is already blooming, while the purple plants won't start blooming for another month or two. When they're all going together, it's fairly spectacular for such a difficult site. After the first year when established, I only give them a little water from the hose maybe once every couple weeks. . . barely any, and they're happy. The first two photos show the globe mallow in its third spring. . . it is almost 3 feet tall and wide now. The third photo is one I planted last year, so this is it's second spring, and it's about half the size. These just started blooming so they're not even really going yet."

Died.

"I bought one to test it in the sidewalk step in front of my Portland Oregon home. Brutally hot and dry in the summer. But, like the rest of Portland, WET in the winter. I planted it in early October. I dug out the clay under the plant and replaced with a mix of sand, clay and compost to give better drainage. But it did not come back this spring. Test failed."

Something eats them

"I really wish that I could grow these without cages! I've tried about 6 so far over three years and I'm going to give up. Something eats them to the ground, probably rabbits. (though deer and skunks could also be culprits)."

— Hiker (3/5)

Survived a wild fire

"Planted on a rocky hillside in Ruidoso NM where we had our second home that was completely destroyed by the wild fires last summer. Took a trip to Ruidoso to put our cleared lot on the market and lo and behold I find this globe mallow that somehow survived the wild fires. This is one tough dude!"

— Desert R. (5/5)

This plant is growing

"My reviews are mixed. Over the years I have limited myself to plants that will grow in clay soil. This globe mallow is growing."

— Hotspringlover (4/5)

Yes

"Plants arrived in good condition, planted in landscape, doing well after three weeks."

— Andrew (5/5)

Globe Mallow Went Crazy Beautiful

"I planted the globe mallow in a rock border because the area looked bare and the soil is heavy clay. I read that it's very waterwise and hearty, so I selected this plant since it's outside our sprinkler zone and needs to be water manually. It grew like crazy with little care. It has pretty little orange flowers and berries that are fragrant, although heads-up--lots of berries end up on the ground. It is now about 4 feet tall and 7-8 feet wide. I love it so much that I would like another! I hope they come back into stock soon."

— Vic (5/5)

Happy-Ish

"Have tried to grow three of these in northern Michigan. This is not their ideal environment so it is my own fault for trying to make something work that I know isn't best suited. One of the three is still alive and growing but it isn't terribly happy. Ultimately, this isn't a knock on the quality of the plant as sold but hoping to add awareness that this plant is a little less adaptable to different environments than some other plants."

— Michigan G. (3/5)
