Begonia Pandora is a striking rex begonia grown for its dramatic foliage rather than its flowers. It has broad, slightly spiralled leaves with a rich mix of deep green, silver and burgundy tones. The centre of each leaf often appears almost metallic silver, fading into darker green edges with a reddish-purple underside. Fine veining and a lightly textured surface give the plant an almost painted appearance.

Begonia Pandora forms a compact, bushy mound, making it ideal for shelves, desks, terrariums or as part of a houseplant display. Mature plants usually reach around 20–30cm tall and slightly wider over time. Although it may produce small pale pink flowers, these are secondary to the beautiful foliage.

Like many rex begonias, Begonia Pandora has a luxurious, almost velvety look which works especially well alongside darker plants or silver-toned foliage in your collections. It is particularly effective when paired with plants from your darker and pink-toned collections, as the silver and burgundy shades complement both beautifully.

Detailed Care Guide

Light

Begonia Pandora prefers bright, indirect light. A spot near an east or north-facing window is ideal, or slightly back from a brighter south or west-facing window.

Avoid direct sun, especially during the middle of the day, as this can scorch and fade the leaves. Too little light may cause the colours to become dull and the plant to grow more slowly.

Watering

Keep the compost lightly moist but never wet.

• Water when the top 2–3cm of compost feels dry
• Reduce watering slightly in winter
• Never allow the plant to sit in water

Begonia Pandora dislikes both drought and overwatering. If the compost stays too wet, the stems and roots can quickly rot. It is usually better to let it dry slightly between waterings than to keep it constantly wet.

Try to water around the base of the plant rather than directly onto the leaves, as wet foliage can sometimes encourage mildew or spotting.

Humidity

This begonia prefers moderate to high humidity, ideally around 50–70%.

If your home is dry, particularly in winter, you can increase humidity by:

• Placing it near other houseplants
• Using a pebble tray with water beneath the pot
• Using a humidifier nearby

Avoid misting directly onto the leaves, as rex begonias can be prone to leaf spotting when water sits on the foliage.

Temperature

Begonia Pandora prefers warm indoor temperatures between 18–24°C.

Keep it away from:

• Cold draughts
• Radiators
• Open windows in winter
• Temperatures below 15°C

Sudden changes in temperature can cause leaf drop or crispy edges.

Compost

Use a light, airy, well-draining compost mix. A good blend would be:

• 2 parts houseplant compost
• 1 part perlite
• 1 part orchid bark or coco chips

This helps retain a little moisture whilst still allowing excess water to drain away.

Feeding

Feed once every 2–4 weeks during spring and summer with a balanced liquid houseplant fertiliser at half strength.

Do not overfeed, as too much fertiliser can damage the roots and cause the leaf edges to brown. Feeding is usually not needed during autumn and winter.

Repotting

Begonia Pandora prefers to be slightly snug in its pot, so it does not need frequent repotting.

Repot every 1–2 years in spring if:

• Roots are growing out of the drainage holes
• The compost is drying out very quickly
• The plant has become too large for its pot

Only move it into a pot one size larger.

Common Problems

• Crispy brown edges: Usually caused by low humidity, dry compost or too much direct sun
• Yellow leaves: Most often from overwatering
• Limp or mushy stems: Usually root rot caused by soggy compost
• Faded leaf colour: Not enough light
• Brown patches on leaves: Sun scorch or water sitting on the leaves

Pet Safety

Begonia Pandora is considered toxic if eaten and should be kept away from pets and young children. The leaves and stems can irritate the mouth and stomach if consumed.
