Begonia (Tuberous types)

Tuberous Begonias

Tuberous begonias are the showstoppers of the shade garden. Known for their extravagant blooms and velvety foliage, these species and hybrids form from underground tubers that store energy through dormancy and erupt into color in the growing season. Native to the Andes and subtropical regions of South America, they offer a dazzling variety of flower forms—ruffled, rose-like, fringed, or cascading—with petals in nearly every shade but true blue.

Grown primarily for their flowers, tuberous begonias bloom for months and do best in cool, filtered light. Their soft, succulent leaves are often asymmetrical and textured, adding another layer of beauty even when not in bloom.

Care Guide

• Light: Bright, indirect light or dappled shade. Avoid harsh sun, which can scorch leaves.

• Water: Keep soil consistently moist but not soggy. Allow the top inch to dry slightly between waterings. Never let the tuber sit in standing water.

• Humidity: Prefers moderate humidity (40–60%). Good airflow helps prevent mildew.

• Temperature: Thrives in 60–75°F. Sensitive to frost—bring indoors or store dormant tubers if temps drop.

• Soil: A loose, well-draining mix with peat, perlite, or compost. Avoid heavy soils.

• Fertilizer: During active growth (spring through summer), feed every 2–3 weeks with a balanced, diluted fertilizer.

Dormancy Note

In fall, as the days shorten, the plant will begin to yellow and fade. This is normal. Stop watering, let the foliage die back, and store the tuber in a cool, dry, dark place until spring. Repot and resume watering when new growth appears.

Why We Love It

There’s no substitute for the sheer glamour of a tuberous begonia in full bloom. Whether upright in pots or trailing from hanging baskets, their lush flowers and soft textures bring a romantic, almost painterly quality to shady patios, windowsills, and bright interiors.
