Cocktail begonias are a series of hybrid begonias that work well in hanging baskets, patio containers or as mass plantings in flower beds. The plants, which grow between 6 and 8 inches tall, are dependable summer bloomers.
Cocktail begonias are tender perennials that return year after year in the mild climates of U.S. Department of Agriculture hardiness zones 10 and above. In cooler climates, cocktail begonias are grown as annuals.
Cocktail begonias are available in a variety of colors, including pink, rose-pink, white with red edges, scarlet and white. The foliage of cocktail begonias is a coppery bronze shade.
Cocktail begonias do well in well-drained soil and full to partial sunlight. Cocktail begonias, a type of wax begonia, benefit from afternoon shade in hot climates. Soil should be allowed to dry slightly between waterings. A 2- to 3-inch layer of mulch will keep the soil moist and cool.
