Dahlias are a standout favorite in backyard gardens thanks to their bold blooms, wide range of colors, and long flowering season. From midsummer until the first frost, dahlias produce eye-catching flowers in shapes ranging from simple and elegant to full and dramatic.
They grow well in garden beds and containers and are easy to customize to any space with the right variety. From classic garden staples to compact options, these are the most popular varieties of dahlias to grow in your backyard.
1. Decorative Dahlias
Decorative dahlias are one of the most popular dahlia types for backyard gardens. They feature large, fully double blooms with broad petals that create a full, layered look. These dahlias come in many colors and sizes and grow well in garden beds where they can be staked for support.
2. Dinnerplate Dahlias
Dinnerplate dahlias are known for their massive flowers, which can reach 8 to 12 inches across. They make a dramatic statement in the garden and are often grown as focal plants. Because of their size, these dahlias need sturdy staking and plenty of sun to perform well.
3. Ball Dahlias
Ball dahlias produce perfectly rounded blooms with tightly packed petals. They are popular for their neat appearance and strong stems that hold up well in wind and rain. These dahlias are excellent for both garden displays and cut flower arrangements.
4. Pompon Dahlias
Pompon dahlias are similar to ball dahlias but smaller and more compact. Their perfectly shaped, globe-like flowers add texture and charm to garden beds. These dahlias are easy to grow and are especially popular in smaller gardens and cutting gardens.
5. Cactus Dahlias
Cactus dahlias are known for their long, narrow petals that give the flowers a spiky, dramatic appearance. They bloom continuously through the season and add visual interest to mixed flower beds. This variety is a favorite for gardeners who want bold texture and movement.
6. Semi-Cactus Dahlias
Semi-cactus dahlias have pointed petals like cactus dahlias, but with a slightly fuller and softer appearance. They offer a nice balance between dramatic texture and classic form. These dahlias bloom heavily throughout the season and do well in sunny garden beds with proper staking.
7. Single-Flowered Dahlias
Single-flowered dahlias have one row of petals surrounding an open center, making them especially attractive to pollinators. They are easy to grow and require less staking than larger varieties. These dahlias work well in natural-style gardens and mixed borders.
8. Collarette Dahlias
Collarette dahlias feature a single row of outer petals with a smaller ring of contrasting petals around the center. This unique flower form adds visual interest without being overly large. They are great for backyard gardens where pollinators and color variety are a priority.
9. Anemone Dahlias
Anemone dahlias have a raised center made up of tubular petals, giving them a soft, cushion-like appearance. They bloom consistently and are less top-heavy than larger dahlia types. These dahlias are a good choice for gardeners who want distinctive blooms with easier maintenance.
10. Waterlily Dahlias
Waterlily dahlias have flat, broad petals arranged in layers that resemble waterlilies. They offer a more relaxed, elegant look compared to highly structured varieties. These dahlias are well suited to garden beds and are easy to mix with other flowering plants.
11. Bishop Series Dahlias
Bishop series dahlias are known for their dark, almost black foliage paired with bright, open blooms. They are compact plants that don’t usually require staking and are excellent for borders and smaller garden spaces. Their open flower centers also make them great for pollinators.
12. Karma Series Dahlias
Karma series dahlias are bred for strong stems, vibrant colors, and excellent cut flower performance. They produce uniform blooms and hold up well in the garden. These dahlias are popular with home gardeners who want long-lasting flowers for both outdoor display and indoor arrangements.
13. Gallery Series Dahlias
Gallery series dahlias are compact, bushy plants designed for containers and small garden beds. They produce large blooms relative to their size and bloom early in the season. These dahlias are ideal for patios, balconies, and limited backyard spaces.
14. Border Dahlias
Border dahlias are medium-height plants that fit perfectly between tall dahlias and low-growing flowers. They provide plenty of blooms without overwhelming nearby plants. This type is great for creating layered garden designs in backyard beds.
15. Miniature & Dwarf Dahlias
Miniature and dwarf dahlias stay small but still produce vibrant, colorful flowers. They are easy to manage and require little to no staking. These dahlias are perfect for containers, raised beds, and beginner gardeners.
