  • A stunning, large-leaved ‘Rex’ Begonia with burgundy coloured foliage and an intriguing ring of Jackson Pollock-esque, pink and white speckles that resemble paint splashes and help to define the leaf shape. Plonk this eye-catching foliage plant on a windowsill with indirect light, or use it as summer bedding, teaming it with a splattering of Erigeron karvinskianus nearby and keep it in pots or hanging baskets on shadier patios.

    We’re proud to support our British growers, and having been raised by one of our trusted UK nurseries, this indoor plant has a low carbon footprint, which makes it perfect for an eco-friendly collection or gift.

  • Home care:
    Rex begonias require special care during the summer months. It's best to keep them in shaded areas and provide ample watering, ensuring proper drainage and maintaining a humid atmosphere around the plants. Avoid wetting the leaves or the crown.

    As winter approaches, reduce the frequency of watering. Allow the compost surface to dry out before watering again. These begonias thrive with a minimum winter temperature of 13°C (55°F) across all varieties.

    For optimal growth, feed them every two weeks from May to September using a high nitrogen fertiliser.
