Our "Bloom or Bust" Promise

Tuberous begonias were created by Victorian-era breeders who crossed several South American species to achieve the huge, camellia-like blooms we know today, turning them into classic conservatory and patio plants.

Begonia 'Double White' produces pure white, rose-like double blooms for a bright, elegant display, bringing rich colour and a soft, petal-packed look to summer containers and sheltered borders from early summer onwards.

Forming a compact, upright growth, this tuberous begonia typically reaches an established height of around 30–50 cm in a single season, with repeat-flowering stems that keep the display fresh when you remove faded blooms.

Start tubers in a frost-free place in spring, then plant outside once all risk of frost has passed. Choose humus-rich, well-drained soil and a sheltered spot with bright shade or gentle morning sun, as strong midday sun can scorch leaves and flowers.

Water carefully until growth is established, then keep the compost evenly moist (never waterlogged). Feed every two to three weeks through the growing season for stronger flowering, and protect plants from heavy rain and wind to prevent damage to the blooms.

Ideal for patio pots, window boxes and shaded beds, these begonias provide long-lasting colour and are easy to overwinter: lift the tubers after the first frost, dry them off, and store in a cool, frost-free place until spring.

Where to Plant:

Begonia 'Double White' does best in bright, sheltered shade or gentle morning sun, in fertile, well-drained soil or quality compost. Begonias are excellent for pots, window boxes and the front of shaded borders where they provide reliable summer colour.

How to Plant:

Start tubers indoors from March or April in moist, free-draining compost. Set the tuber with the hollow side facing upwards, just 1–2cm below the surface. Move outside in May once frosts have passed, spacing plants around 20–30cm apart.

Aftercare:

Water sparingly until shoots appear, then keep the compost evenly moist without letting plants sit in water. Feed every two to three weeks during active growth and remove spent flowers to encourage more blooms. In autumn, lift and dry tubers after the first frost, then store them cool and frost-free until spring.
