These are hybrids of B. socotrana and tuberous begonia varieties. Often called winter-blooming begonia, ongoing breeding offers gorgeous new varieties that are available in bloom any time of year.

Begonias are full, bushy, and low-growing. Their thick, reddish stems grow from tuberous roots under the soil.

Big, soft, dark-green leaves create a beautiful backdrop for abundant clusters of delightful flowers that are available in orange, white, yellow, red, and pink.

Tuberous begonias will go dormant after flowering, but you can bring them back into bloom, if you want. See "After-blooming begonia care" below to find out how.

Growing Begonias Year-Round

Keep the soil moist. Allowing it to dry out will leave the plant susceptible to disease. But you don't want soggy soil, either. Overwatering your begonia will cause leaves to wilt and turn yellow. Cut off any affected leaves as soon as you notice them. They're likely to rot and attract botrytis fungus.

Shed some light. Give your begonia plenty of bright light while it's blooming, but keep it out of direct sunlight which can scorch its leaves.

Cut off spent flowers. Prune off dead flowers to keep your plant looking neat and to encourage more blooms.

After-blooming begonia care. They are challenging to maintain and regrow the following season, so they are often treated as temporary house plants. However, it's entirely possible to bring them back into bloom the following year. After flowering, cut back on watering so that the plant is barely moist, but not completely dry. Keep it away from light during this dormant period. In about 6-8 weeks, the foliage will die back. Cut off all the foliage, leaving 3 in (7.5 cm) stems. When new growth appears, remove the stems from the parent plant and pot them in new potting mix. You can discard the parent plant.

Origin: Hybrids of Begonia socotrana (discovered on the island of Socotra, off the coast of East Africa) and tuberous hybrids (with origins from South America)

Height: 12-18 in (30-45 cm)

Light: Bright light

Water: Keep soil evenly moist, not soggy. Allow top inch of soil to dry between waterings.

Humidity: Medium to high. Keep pot on a tray of wet pebbles to increase humidity.

Temperature: Cool nights (55-60°F/13-16°C) and warm days (65-75°F/18-24°C) will trigger flower buds.

Soil: Peat-based soilless mix such as African violet potting mix works well. Use a pot with drainage holes.

Fertilizer: Feed every 3 weeks with a high-phosphorus liquid fertilizer diluted by half while plant is blooming.

Propagation: Take 3-4 in (7-10 cm) stem tip cuttings at the beginning of the growing season and root in fresh potting mix.




Green Thumb Tip

Begonias are prone to powdery mildew -- a powdery white fungus on its leaves.

Spray an affected plant with a fungicide and keep it away from other plants to prevent it from spreading.

Buying Tips

When buying a new plant, it's best to choose one that has good bud color and has just started to bloom.

You'll sometimes find these plants labeled as Elatior or Reiger hybrids, but they include many varieties.
