Wax begonias are one of those easy-going summer annuals in the Pacific NW, tolerating sun or partial shade, are drought tolerant, and bloom all summer long. Forming dense mounds of succulent-like leaves about a foot tall and wide, this variety is perfect for borders, mass plantings, container planters and hanging baskets. 'Ambassador Mix' includes white flowers and a range of pink and red blooms, all with yellow eyes.
