Begonia × tuberhybrida Copper - Double grandiflora orange begonia

Begonia Grandiflora Copper is a tuberous begonia that offers large double flowers in coppery orange tones, ideal for flowering shaded areas of the garden, terraces and balconies. Compact and very floriferous from summer to autumn, it is easily grown in pots, planters and borders where it brings a warm colour. This plant is not frost hardy and is grown as a seasonal perennial whose tubers are overwintered dry.

Belonging to the Begoniaceae family, Begonia Grandiflora is a selection of Begonia × tuberhybrida (or tuberous begonia) that is not trailing, with large upright flowers. "Copper" refers to a coppery colour, not a registered cultivar. The plant has a bushy, upright, even slightly spreading habit. It most often reaches 25–30 cm in height and 30–35 cm in width within a season. Its stems are fleshy, brittle, green to reddish. They bear compound foliage formed of asymmetrical, heart-shaped to ovate leaves, 10 to 15 cm long, medium to dark green, glossy, with a finely toothed margin. They are deciduous in winter, as the plant goes dormant.
The long flowering lasts from June to October. The double flowers, shaped like an open rose, measure 8 to 10 cm in diameter; the "copper" hue ranges from burnt orange to coppery apricot depending on exposure and temperature. The plant grows from a flattened tuber that should be stored dormant, dry, protected from frost, at 5/8 °C, after the foliage yellows.

Place this double coppery begonia in your pots and planters in partial shade, under an awning or in a sheltered flower bed. Pair it with anise green or bronze foliage, for example, Heuchera ‘Kassandra’, Hosta 'Limey Lisa' or Carex oshimensis ‘Everillo’. A Hardy Fuchsia ‘Mrs Popple’ will lighten the whole. You can also mix several varieties of Grandiflora begonias of different colours: the coppery tones blend perfectly with orange and red.

Belgian Flanders is an important area of tuberous begonia production, with massive tuber export; the commercial name "Copper" is common among specialised wholesalers.
