White Wax Begonias Wax begonias are tender perennials in Zones 8-11 but I grow them as a flower suitable for edging beds in light shade. It has waxy leaves and produces clusters of single or double white flowers. Wax begonias bloom non-stop throughout the entire season until first frost. It looks great with another annual, Purple Angelonia, as I planted here.
