Dahlias for Summer Blooms

One of the most popular choices for summer flowering plants is dahlias, known for their large, vibrant flowers that add a touch of elegance to any garden. Dahlias come in various sizes and shapes, making them perfect additions to gardens with different styles.

Dinnerplate Dahlias for Impressive Size

Dinnerplate dahlias, as the name suggests, can measure up to 12 inches in diameter and are sure to impress anyone who sees them. These showy flowers bloom throughout the summer months and thrive best in full sun conditions with regular watering. I order all of my Dahlia bulbs from Eden Brothers. 

Pom-Pom Dahlias for Charming Appeal

If you’re looking for something smaller but equally eye-catching, consider planting pom-pom dahlias. These miniature beauties grow beautiful round-shaped blooms that resemble pom-poms. They also require full sun exposure and well-drained soil during their growing season from late spring through early fall.

  • Pro Tip: To ensure your dahlias produce bright yellow flowers or other stunning colors all summer long, make sure they receive at least six hours of sunlight daily.

Dahlias are not the only summer flowers that bloom all season long. Other perennial flowers that can add beauty to your garden include:

  • Stella de Oro Daylily: This plant grows beautiful showy flowers with dark green foliage. It is drought-tolerant and blooms from early summer through late fall.
  • Black-Eyed Susan: This plant produces beautiful bright yellow flowers with dark centers and can grow up to three feet tall. It is an annual flower that blooms from early summer through late fall.
  • Salvia: This plant grows beautiful tiny purple, pink, or blue flowers and is a favorite among gardeners. It is drought-tolerant and blooms from early summer through late fall.
  • Butterfly Bush: This plant produces beautiful fragrant flowers that attract butterflies and hummingbirds. It requires full sun exposure and regular watering during its growing season from early spring through late fall.

When choosing summer flowering plants, it’s important to consider the growing conditions in your area. Some plants thrive in full sun, while others prefer partial shade. Additionally, some plants are drought-tolerant, while others require regular watering. By choosing the right plants for your garden, you can enjoy beautiful blooms all summer long. Dahlias are a great choice for bringing vibrant color to your garden during the summer months. A broad range of sizes and hues make dahlias a great option for adding life to your garden throughout the year. Now let’s take a look at how you can incorporate other perennials into your outdoor space for year-round beauty.

Whether you prefer annual flowers or perennial flowers, there are plenty of options to choose from. Just make sure to plant them in the right growing conditions, such as full sun or partial shade, and provide regular watering and care.

Tropical Flair with Bougainvilleas and Zinnias

Add a tropical flair to your garden by planting bougainvilleas, vibrant vines perfect for outdoor areas. These summer flowering plants are known for their showy flowers that come in a variety of colors, including bright yellow and white. To ensure healthy growth, plant bougainvilleas in well-draining soil and provide them with plenty of sunlight. Zinnias also make an excellent addition to any garden during the growing season. They require full sun exposure and come in almost every color except blue, making them versatile choices for any gardener looking to brighten up their space during the hot season. Some popular varieties include:

  • Giant Dahlia Flowered Zinnias: Known for their large blooms resembling dahlias.
  • Lilliput Mix Zinnias: Compact plants producing small pom-pom-like blooms.
  • Cactus Flowered Mix Zinnias: Unique quilled petals create a cactus-like appearance.

To grow zinnias successfully, sow seeds directly into the ground after the last frost or start indoors about six weeks before transplanting outdoors. They prefer well-drained soil and regular watering throughout the summer months but can tolerate some drought conditions once established. For a summer-long display of beautiful flowers, consider planting perennial flowers such as the Stella de Oro Daylily. This plant grows well in full sun to partial shade and moist soil and produces fragrant, bright yellow flowers throughout the summer months. Another option is to plant annual flowers such as cosmos or marigolds, which bloom all summer long and come in a variety of colors, including white, pink, and orange. If you’re looking for drought-tolerant plants, consider sedums or lavender. Sedums are low-maintenance plants that come in a variety of colors and bloom in late spring to early summer. Lavender, on the other hand, produces showy flowers in late spring to early summer and has dark green foliage that looks great all season long. Both plants are drought-tolerant and require minimal watering once established. Attract butterflies to your garden by planting black-eyed susans or butterfly bushes. Black-eyed susans produce bright yellow flowers with dark centers and bloom from early summer to late fall. Butterfly bushes produce fragrant flowers in shades of pink, purple, and white and attract butterflies and hummingbirds to your garden. With these summer flowering plants, you can enjoy a beautiful garden all season long. Remember to provide regular watering and care to ensure healthy growth and vibrant blooms through late summer. Bougainvilleas and Zinnias add a tropical flair to any garden, but for an extra special touch, Foxgloves and Carnations can take it up another level. With their unique care requirements and variety of colors available, these showy flowers are sure to brighten your summer days.

Summer Flowering Plants: Foxgloves and Carnations

Add elegance to your garden with foxgloves and carnations, two beautiful summer flowering plants that will bloom all summer long.


Foxgloves can reach heights of up to six feet tall when given ample sunlight and well-drained soil.
