Fun Facts

- 🌱 Acalypha wilkesiana is native to the South Pacific (Fiji, New Guinea, and nearby regions) and was introduced to cultivation in Hawaii and other tropical regions in the 1800s, where it became a beloved ornamental.
- 🌱 The genus name Acalypha comes from the Greek word for 'nettle,' and some species in this genus have stinging hairs, though A. wilkesiana 'Margined' is harmless and grown purely for its spectacular foliage display.
