Botanical nameBegonia × tuberhybrida
White Double Camelia begonia (Begonia × tuberhybrida ‘White’) forms a compact plant crowned with large, fully double white flowers whose overlapping petals resemble camellia blooms. The Van Noort size 6/+ tuber is sold individually and produces fleshy green foliage that emphasizes the clean colour of each flower. Reaching approximately 30 cm tall, this begonia creates a luminous focal point in sheltered places where darker colours need relief. Its generous summer display is particularly effective in pots, urns, and borders viewed at close range, where the layered texture and balanced shape can be appreciated.
Start the tuber in spring in fresh, rich, porous potting mix with its hollow side facing upward. Cover it lightly, keep the medium warm and barely moist, then increase watering after shoots appear. Once frost danger has passed, acclimate the plant and place it in partial shade protected from intense sun, wind, and driving rain. Water at soil level when the surface dries and let surplus escape. Regular diluted fertilizer supports buds without producing soft stems. Remove spotted flowers promptly to preserve the crisp white presentation and keep decaying petals away from leaves.
Use White Double Camelia begonia to brighten a covered porch, shaded patio, or the front of a protected border. Pair its white blooms with burgundy, silver, or deep green foliage while leaving enough room for air circulation. The plant is strictly ornamental and its tissues must not be eaten. Before the first frost, bring the pot indoors or lift the tuber when foliage yellows. Let it dry, clean it gently, and store it in a cool, dry, dark, ventilated place until spring. Label the tuber clearly so the white selection remains identifiable among stored begonias.

Growing method
Start the tubers indoors in spring in a light, well-draining substrate, with the concave side facing upwards. Water sparingly before shoots appear and ensure no water collects in the hollow. Keep young plants frost-free until conditions allow them to be moved outdoors. Choose a bright location protected from scorching sun and strong winds. If potting, ensure drainage holes are clear and adjust watering to foliage development. Gradually acclimate plants to outdoor conditions, allowing them to adapt to wind and light without shocking new growth. During growth, maintain consistent moisture without waterlogging the soil. Water at the base and remove damaged or faded flowers to keep the plant tidy. Stems and leaves are fragile: handle containers with care and avoid crowding the plant with more vigorous neighbors. In Quebec, protect tubers from frost for storage. When foliage becomes dormant, reduce watering and allow aerial parts to wither before removing them. Store healthy tubers in a dry, airy, frost-free place during winter, with their labels, then check their condition before replanting.
