Globe Mallow

Sphaeralcea ambigua

Globe Mallow

A rugged Southwestern native available in a palette of orange, white, pink, and lavender that thrives on neglect.

Hardy in USDA zones 6-11; a semi-evergreen low-desert native that shrugs off frost and extreme heat, thriving across low and mid elevations on rainfall alone.

AMWUA Notes

Skin and eye irritant β€” wear gloves when handling.

Care Guide

πŸ’§Watering

Extremely drought tolerant β€” water every 2-3 weeks in summer and rarely otherwise; it blooms on rainfall and rots in overly wet or poorly drained soil.

βœ‚οΈPruning

Shear the whole plant back by half after the spring bloom to remove spent stalks, tidy the sprawl, and often trigger a lighter second flush; wear gloves, as the foliage hairs irritate skin.

🌱Fertilizing

None needed; it thrives on lean, unimproved desert soil.

πŸ›‘οΈPests

Essentially pest-free; the main issue is a floppy, open habit if overwatered or grown in rich soil.

β˜€οΈSeasonal Notes

Semi-evergreen perennial that peaks in spring, especially after wet winters; short-lived but reseeds prolifically to renew the stand.

Soil, Feeding & Propagation

πŸͺ¨Soil

Lean, rocky, gravelly, fast-draining desert soils; thrives on hot, dry, disturbed ground; rots in rich or overwatered soil.

πŸ’§Drainage

Needs sharp, fast-draining soil.

🌱Nutrient Needs

None β€” thrives in lean desert soil without fertilizer.

🌰Propagation

Seed; reseeds prolifically. The deep taproot makes it difficult to transplant except as young seedlings.

πŸ“Spacing

3 ft

🌳Roots & Placement

Deep taproot resents disturbance; short-lived but reseeds freely into volunteers. Wear gloves, as foliage hairs irritate skin.

Placement Tips

  • β€’Mass in natural and wildflower plantings for a spring sweep of glowing orange or pastel bloom.
  • β€’Give it room to sprawl and reseed; expect volunteers to fill in over time.
  • β€’Site in the hottest, driest, reflected-heat spots where fussier plants fail.
  • β€’Wear gloves when handling or shearing, since the fine leaf hairs can irritate skin and eyes.
