Fun Facts
- 🌱 Begonias are named after Michel Bégon, a French botanist and governor of French Canada in the 17th century, making them living botanical tributes.
- 🌱 Wax begonias are called 'wax' begonias because their leaves have a distinctive waxy coating (epicuticular wax) that gives them a shiny, polished appearance and helps them retain moisture.
- 🌱 These begonias are nearly pest-resistant marvels due to their foliage chemistry—some studies suggest their leaves contain compounds that naturally deter certain insect pests.
