We love the selection of bulbs available from A.D.R. The variety is great, the quality is excellent and the price is fair. However, the best part of working with A.D.R is the customer service from Chris, Walter and all of the team. They go out of their way to make sure ours needs are met.

Begonia Superba 'Red' (Ships in Spring)

Begonia

Begonia 'Superba Red' is an upright, double-flowered variety with large, ruffled scarlet-red blooms that create a bold display from midsummer 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 makes it wind-resistant, ensuring long-lasting floral impact in containers 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 'Red' (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.
