Begonia 'Superba White' is an upright, double-flowered variety with large, fully double blooms in a crisp white hue. Flowers measure 5 to 6 inches across, creating an elegant display from summer until frost. Growing 8 to 12 inches tall, it thrives in partial shade to full shade and prefers rich, well-drained soil with consistent moisture. Its compact growth habit ensures a neat, full appearance, making it ideal for containers, shaded borders, and garden beds. In colder climates, tubers should be lifted and stored indoors before winter to ensure a fresh display the following season.
