Harvest Tips
Semperflorens White is an ornamental flower. Deadhead spent blooms regularly by pinching off faded flowers at the base of the stem to promote continuous flowering throughout the season. Cut stems can be used in small floral arrangements; harvest in morning after dew dries. In warm climates where plants persist year-round, prune back severely in late winter or early spring to rejuvenate growth.
Fun Facts
- 🌱 Semperflorens begonias are named 'semperflorens' which means 'ever-flowering' in Latin, referring to their remarkable ability to produce flowers continuously throughout warm months with minimal deadheading.
- 🌱 Wax begonias have waxy-coated leaves that make them highly resistant to powdery mildew compared to other begonias, and this feature is also why their foliage is attractive and water-resistant.
- 🌱 Unlike their tuberous relatives, Semperflorens begonias are fibrous-rooted and can be easily propagated from stem cuttings in water, making them ideal for sharing with gardeners and creating new plants throughout the season.
