About California Copperleaf (Acalypha californica) The flowering shrub Acalypha californica is known as the California copperleaf, and sometimes by the older name Pringle three-seeded mercury. It is the only Acalypha species native to California, where it is found from the Peninsular range foothills hills into the lower desert of San Diego County. It is a member of the chaparral plant community and most often grows in crumbling granite rocks, ledges and cliff faces, though it occasionally grows in sand washes. The plant bears beautiful light green serrated leaves with wavy hairy edges. Younger leaves tend to have pink or red edges. Older leaves turn pinkish or copper-colored in summer months. Stems are white, pink or red. Flowers appear as bumpy pinkish red spikes, sometimes with white speckles, growing out from the base of the leaf stems. It typically grows in a rounded mounding form. Beautiful plant but difficult to find in nurseries. It can be easily grown from winter cuttings though. Larger woody cuttings work best.
