They bloom best with short days and cool temperatures, and will often bloom for up to six months.
Do begonias bloom all year long?
Once begonias start flowering, they bloom continuously from summer to frost. There are several different types of begonias. Wax begonias and angel-wing begonias are usually grown as outdoor annuals or indoor houseplants. Both grow from a clump of roots and are winter hardy in growing zones 9-11.
What months do begonias bloom?
Begonias grow in moist, shady gardens where they have well-drained soil, wind protection and filtered or indirect sunlight. A typical blooming season starts in June and ends with the first frost. They are so easy to grow that a broken stem or leaf stalk stuck in soil often roots as a new plant.
