Discussion

Acalypha wilkesiana is not known in the wild, but presumably originated in the southwestern Pacific Islands (Bismarck Archipelago east to Fiji). The species is commonly cultivated as an ornamental for its leaves that may be various shades of green, purple, red, orange, and yellow (sometimes variegated), and sometimes contorted into unusual shapes. Despite low seed set, it occasionally becomes naturalized in tropical and subtropical areas. Naturalized plants often lack the distinctive leaf coloration found in cultivated plants. Although sometimes treated as A. amentacea subsp. wilkesiana, DNA sequence data show that A. wilkesiana and A. amentacea are distinct species (V. G. Sagun et al. 2010).
