The Best Summer-Flowering Bulbs for a Stunning Garden

When most people think of planting bulbs, they picture bright tulips and cheerful daffodils welcoming spring. But summer-flowering bulbs bring a whole new level of beauty to the garden, offering months of color and texture with minimal effort. If you want a stunning summer garden, these easy-to-grow bulbs—dahlias, lilies, gladiolus, and begonias—are must-haves. 

 

Dahlias: Bold and Beautiful Blooms 

Dahlias are the showstoppers of the summer garden. Available in a dazzling range of colors, shapes, and sizes, these tuberous bulbs bloom from mid-summer until the first frost. Their intricate, layered petals and sturdy stems make them a favorite for garden beds and cut flower arrangements. 

Growing Tips: 

  • Plant in full sun after the danger of frost has passed. 
  • Ensure well-draining soil enriched with compost. 
  • Support taller varieties with stakes to prevent flopping. 
  • Deadhead spent flowers to encourage continuous blooming. 

 

Summer-Flowering BulbsLilies: Elegant and Fragrant 

Lilies add a touch of elegance to any garden with their graceful, trumpet-shaped blooms and intoxicating fragrance. From classic Asiatic and Oriental lilies to exotic tiger lilies, these bulbs provide long-lasting color and attract pollinators like butterflies and hummingbirds. 

Growing Tips: 

  • Plant in early spring or fall in a sunny or partially shaded spot. 
  • Choose well-draining soil and plant bulbs about 3x their height deep. 
  • Water regularly but avoid soggy conditions. 
  • Mulch to keep roots cool and moist. 

 

 

Gladiolus: Vertical Color Spikes 

If you want to add height and drama to your summer garden, gladiolus is the way to go. These tall, sword-like blooms come in nearly every color and make excellent cut flowers. They bloom in succession, ensuring a steady display of vibrant color throughout the season. 

Growing Tips: 

  • Plant after the last frost in groups for a fuller effect. 
  • Choose a sunny location with loose, well-draining soil. 
  • Stagger plantings every couple of weeks for continuous blooms. 
  • Provide support for taller varieties to prevent bending. 

 

 

Summer-Flowering BulbsBegonias: Shade-Loving Showstoppers 

Unlike the other bulbs on this list, begonias thrive in partial shade, making them perfect for brightening up shady spots. Their lush, ruffled blooms in red, pink, yellow, and white pair beautifully with their rich green or bronze foliage. 

Growing Tips: 

  • Start tubers indoors in early spring or plant directly outside after frost. 
  • Choose well-draining, moisture-retentive soil for best results. 
  • Keep them evenly watered but avoid overwatering. 
  • Remove spent flowers to encourage continuous blooming. 

 

Bonus Tip: Storing Summer Bulbs for Next Year 

Unlike spring-flowering bulbs that stay in the ground over winter, most summer bulbs need to be lifted and stored in colder climates. After the first frost, dig them up, allow them to dry, and store them in a cool, dry place for replanting next year. 

Create a Stunning Summer Garden with These Easy Bulbs 

With the right mix of summer-flowering bulbs, your garden can be a vibrant paradise from June through fall. Whether you’re drawn to the boldness of dahlias, the elegance of lilies, the towering beauty of gladiolus, or the lush charm of begonias, these bulbs will ensure a breathtaking display all season long.
