Fill shaded patios, window boxes, and garden edges with rose-like blooms all summer. Pink Double Begonia bulbs produce lush, layered flowers in soft pink on tidy plants that shine in containers, hanging baskets, and dappled garden corners. They thrive in part shade to full shade, ask for modest care, and reward you with a continuous, elegant display from early summer to frost.

Plant in rich, well-drained soil and keep the mix evenly moist, never soggy. Set each tuber shallow with the concave (hollow) side facing up and the growing points just below the surface. Morning sun with afternoon shade or bright, indirect light is ideal. Feed lightly during active growth, remove spent blooms to keep flowers coming, and protect foliage from slugs and snails. In cold regions, lift and store tubers for next year.

FAQs

What are Pink Double Begonia “bulbs,” and what makes them different?

They’re tuberous begonias grown from firm, flattened tubers rather than true bulbs. “Double” describes the flower form—full, rose-like petals for a plush, romantic look that stands out in shade.

When and how should I plant the tubers?

Plant in spring after the last frost when soil is at least 60°F. Place each tuber just below the surface with the concave side up, cover lightly, and water to settle. Start indoors 4–6 weeks early if you want a head start, then harden off and move outside once nights are reliably warm.

Do they grow well in containers or indoors?

Yes—containers and hanging baskets are ideal. Use a high-quality potting mix in a pot with drainage and give bright, indirect light. Indoors, they’ll bloom with strong light but usually perform best outside in shaded settings once temperatures are mild.

How do I keep blooms coming all season?

Maintain even moisture, feed every few weeks with a balanced fertilizer, and remove spent flowers. Keep plants out of harsh afternoon sun and protect leaves from slugs and snails for the best display.

How do I overwinter the tubers?

After the first light frost or when growth naturally slows, let foliage yellow, then cut it back. Lift the tubers, brush off soil, and cure in a warm, airy spot for a few days. Store in a cool, dry place (around 45–55°F) in paper bags or dry peat. Replant in spring for another season of color.
