Begonia Seeds: How to Grow Stunning Flower Seeds for Containers, Hanging Baskets & Landscapes

Begonia seeds are among the most versatile and rewarding flower seeds you can grow, offering nonstop color for containers, hanging baskets, shaded landscapes, and greenhouse production. From compact bedding begonias to trailing varieties ideal for baskets, begonias grown from seed allow gardeners and growers to access more varieties, better uniformity, and healthier plants than transplants alone.

At Garden Starts Nursery, we specialize in high-quality begonia seeds for home gardeners, cut-flower growers, and commercial producers alike. Whether you’re planting small quantities for containers or sourcing bulk begonia seed packs for greenhouse production, growing begonias from seed gives you unmatched flexibility and control.

Why Grow Begonias From Seed?

Growing begonias from seed opens the door to hundreds of varieties that are rarely available as plugs or finished plants. Seed-grown begonias are also:

  • More economical than transplants

  • Easier to scale for mass planting

  • Healthier and disease-free when started properly

  • Available in a wider range of colors and habits

For gardeners focused on performance, begonias consistently rank among the best flower seeds for reliable blooms in partial shade, filtered sun, and containers.

Types of Begonia Seeds

Begonia seeds come in several growth habits, each suited for different garden uses.

Trailing Begonia Seeds

Trailing begonias are ideal for hanging baskets, window boxes, and elevated containers. Their cascading habit creates dramatic color displays that last all season.

How to Grow Begonia Seeds Successfully

Begonia seeds are very small, but with proper technique they are highly reliable.

1. Start Indoors

Begonias are slow starters. Begin seeds 10–14 weeks before last frost for best results.

2. Use a Fine Seed-Starting Mix

A light, sterile mix allows tiny roots to establish easily. Do not bury the seeds.

3. Surface Sow

Begonia seeds need light to germinate. Press gently onto moist soil but leave uncovered.

4. Maintain Warmth & Humidity

Ideal germination temperature: 70–75°F
Use a humidity dome or mist lightly to keep seeds from drying out.

5. Be Patient

Germination usually takes 10–20 days. Growth is slow at first, but once established, begonias grow steadily.

Begonias are prized for their versatility across many garden styles:

  • Hanging baskets with nonstop blooms

  • Patio containers and porch planters

  • Shade gardens and woodland borders
