Fun Facts
- 🌱 Acalypha wilkesiana is commonly called 'Copperleaf' or 'Jacob's Coat' due to its multicolored foliage that resembles a patchwork coat, with names and colors varying by variety.
- 🌱 The plant is native to the South Pacific (Fiji and nearby islands) and requires warm, humid conditions that closely mimic its tropical homeland.
- 🌱 Acalypha's fuzzy flower spikes are technically dense clusters of tiny flowers called catkins, and the plant produces seeds that scatter when ripe, leading to its alternative common name of 'Three-seeded Mercury.'
