Pre-flowering
2-3 weeksPlant reaches mature size with dense foliage; flower buds begin to form at branch tips
Continue pinching if fuller form desired, reduce nitrogen fertilizer, increase phosphorus to promote flowering, maintain bright conditions
Flowering

Fun Facts
- 🌱 Begonias are named after Michel Bégon, a French governor and botanist from the 17th century, and were discovered by French botanist Charles Plumier in the Caribbean.
- 🌱 White begonia flowers are asymmetrical—they have unequal petals and sepals, which is a defining characteristic of the entire Begoniaceae family and quite unique among flowering plants.
- 🌱 Begonias can be propagated from leaf cuttings; a single leaf can generate an entire new plant, making them one of the easiest plants to multiply at home.
