Superstition Mallow
Abutilon palmeri
A subtropical shrub with velvety leaves and orange-yellow flowers that attract bees and butterflies throughout the warm season.
Hardy in USDA zones 9-11; root-hardy through low-desert winters, it may suffer top frost damage below about 25F but recovers, and it thrives in extreme summer heat.
AMWUA Notes
Sonoran native that tolerates reflected heat but rewards supplemental irrigation with a fuller canopy and longer bloom.
Care Guide
Despite being a desert native, this species performs best with regular deep soaks every 5-7 days in summer heat; taper to every 2-3 weeks in winter to keep the velvety foliage full.
Tip-prune lightly to shape and cut back by about one-third in late winter to renew growth; never shear into a formal ball, which ruins its soft natural form and reduces bloom.
A single light application of balanced or slow-release fertilizer in early spring is plenty; over-feeding produces leggy, floppy growth.
Watch for whiteflies and spider mites during the hottest months, especially on drought-stressed plants; a strong hose spray usually knocks them back.
May defoliate or freeze back in a hard frost below the mid-20s but reliably resprouts from the base in spring; blooms heaviest from spring through fall.
Soil, Feeding & Propagation
Adaptable to rocky, sandy, or decomposed-granite desert soils; tolerates caliche and alkaline pH 7.5-8.5 given good drainage.
Needs well-drained soil.
Low feeder.
Grown readily from seed; softwood cuttings root in warm weather.
4 ft
Shallow, non-aggressive roots; safe near walls, pools, and hardscape.
Placement Tips
- •Give it a 4 ft footprint and space plants about 4 ft apart for a soft, informal massing along a border.
- •Site it where it receives afternoon relief or filtered light in the hottest yards; its higher water need makes it a poor fit for pure gravel xeriscape.
- •Use as a mounding filler in front of taller screening shrubs where its long bloom season reads all season.
- •Keep back from pool coping since the soft leaves and spent flowers can drop into the water.
