Begonia Superba 'White' (Ships in Spring)

Begonia

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.

Growing and Maintenance Tips for Begonia Superba 'White' (Ships in Spring)

Planting: Use a light, well-draining potting mix rich in organic matter. Plant tubers just below the surface with the concave side facing up.
Location: Prefers bright, indirect light or partial shade. Protect from intense midday sun to prevent leaf scorch.
Soil: Slightly acidic to neutral (pH 6.0–7.0), enriched with compost or peat moss.
Watering: Keep soil evenly moist but not soggy. Allow the top inch to dry slightly between waterings.
Humidity: Enjoys moderate to high humidity. Mist occasionally or use a humidity tray if grown indoors.
Temperature: Thrives between 60–75°F. Not frost-tolerant—bring indoors or lift tubers before first frost.
Fertilization: Feed every 2–4 weeks during the growing season with a balanced, diluted fertilizer.
Pruning: Remove spent blooms and yellowing leaves to encourage continuous flowering.
Pest & Disease: Watch for powdery mildew, botrytis, and pests like aphids or thrips. Ensure good air circulation and avoid overhead watering.
Overwintering: In colder zones, lift and store tubers in a cool, dry place once foliage dies back.
