Harvest Tips

Begonias are ornamental flowers; deadhead spent blooms regularly by pinching them off at the base to encourage continuous flowering. Pinch back stems in early growth to shape the plant and promote bushiness. In fall, before frost, take cuttings for propagation by rooting 3-4 inch stems in water or moist soil.

Fun Facts

🌱 Red begonias were first bred in the 1960s from the crossing of Begonia semperflorens and Begonia coccinea, creating the popular wax begonia varieties we know today.
🌱 Begonias are named after Michel Bégon, a 17th-century French colonial administrator and plant enthusiast, as a tribute to his contributions to botany.
🌱 The 'wax begonia' common name refers to the glossy, waxy appearance of the leaves, which helps protect them from moisture loss in humid tropical conditions.
