Ambassador Bicolor Dwarf Begonia

Ambassador Bicolor is a compact, green-leaved wax begonia with large flowers in a two-tone pattern. This bedding annual flowers early and has enough vigor for massed color in beds, edging, and seasonal displays; its moderate size also suits mixed containers where consistent foliage and a long flowering window are useful. ## Cultivar and growing conditions The [Sakata Ornamentals Ambassador profile](https://sakataornamentals.com/plantname/ambassador/) identifies Begonia semperflorens as the series species and lists Bicolor as a color option. Sakata describes a green-leaved, early series with large flowers on compact 12-inch plants, about 10 inches wide, and identifies spring-to-summer production. [NParks' wax begonia group profile](https://www.nparks.gov.sg/florafaunaweb/flora/5/6/5614) describes Begonia semperflorens-cultorum as a compact bedding group with green through reddish foliage and single or bicolored flowers. It notes full sun suitability in subtropical or temperate climates, but recommends semi-shade in tropical lowlands. ## Seasonal care Plant after frost danger has passed in a sheltered site with fertile, well-drained soil. Keep the root zone evenly moist during active growth, especially in containers, but provide airflow and avoid persistently wet foliage. The [RHS begonia guide](https://www.rhs.org.uk/plants/begonias/outdoors) similarly recommends regular watering in dry weather and planting outdoors after frost risk. ## Maintenance Water during dry spells and remove spent or damaged blooms to keep the bedding display tidy. Replace plants when frost ends the season, or protect them in a warm frost-free space if retaining them is practical.
