Harvest Tips
Miniature begonias are ornamental flowers, not harvested for food. Pinch spent blooms regularly to encourage continuous flowering. For propagation, take 1-2 inch stem cuttings and root in moist potting soil under humidity dome. Begonias can be divided at the rhizome in spring.
Fun Facts
- 🌱 Begonias are named after Michel Bégon, a French botanist and patron of plant exploration in the Caribbean in the 17th century.
- 🌱 Miniature begonias can be propagated from a single leaf—place a healthy leaf on moist soil and new plantlets will form from the leaf veins.
- 🌱 Begonia flowers are asymmetrical (unequal petals), which is why they're classified in their own family, Begoniaceae, rather than grouped with other flowering plants.
