Mama used to grow wax begonias in pots, as houseplants. I think they're pretty as bedding plants, blooming non-stop.
In really hot climates, impatiens faint and fall over without constant watering. Wax Begonias enjoy water, but they can skip some of those waterings without withering. Begonias cuttings root easily. The colors range from white to red. The leaves may be bright green or a pretty bronze.
