Picking the perfect dahlia isn’t just about aesthetics; it’s a blend of practicality, creativity, and a touch of intuition. With a dazzling array of forms and colors to choose from, there’s a dahlia for every grower. Whether you’re after show-stopping blooms, reliable cut flowers, or a vibrant garden display, here’s how to make a thoughtful choice.
Know Your Purpose
Why are you growing dahlias? The answer will guide your selection.
- Cut Flowers - Look for varieties with long, sturdy stems and good vase life. Florists love options like ‘Thomas Edison’ and ‘Breakout’ for their straight, elegant stems that make arranging a breeze.
- Garden Display - Choose prolific bloomers with eye-catching colors. Varieties like ‘Cornel’ and ‘Sylvia’ shine here, combining beauty with disease resistance.
- Exhibitions - For competitions, prioritize symmetry and size. Varieties bred for the show bench, like ball and decorative forms, are your best bet.
Match Your Climate
Dahlias respond differently to varying environments. Consider these factors.
- Heat - In hot climates, go for varieties with smaller blooms or darker foliage that handle heat better.
- Cold - If you have a short growing season, early bloomers ensure you'll enjoy flowers before the frost.
- Rain - Sturdy varieties with good drainage, like 'Franz Kafka' and 'Zundert Mystery Fox,' are less prone to fungal problems, thanks to their upright growth and compact blooms.
Choose the Right Size and Shape
Dahlias range from tiny to towering, so think about what fits your space.
- Small Blooms - Pompon dahlias, like ‘Rocco,’ are durable and long-lasting, making them great for bouquets.
- Medium Blooms -Versatile and manageable, these work well in gardens and vases alike
- Giant Blooms - Dinner plate varieties such as ‘Islander’ make a bold statement but need staking to support their heavy heads.
Think About Color
Color is key, especially if you’re designing for specific purposes.
- Pastels - Soft shades like blush and cream are perfect for weddings.
- Bold Colors -Bright reds, oranges, and yellows add drama to gardens and bouquets.
- Sunlight Considerations - Deep reds and purples may fade in intense sunlight, while lighter colors can appear washed out in shade.
Consider Maintenance
Some dahlias are more hands-on than others.
- Low Maintenance - Single-flowered varieties dry quickly and require less deadheading.
- High Maintenance - Intricate forms, like cactus dahlias, may need extra attention to keep their shape intact.
Look for Disease Resistance
Varieties with tightly packed petals and upright growth are often the most resilient to pests and diseases. Their structure helps keep earwigs out and sheds water quickly, reducing the risk of fungal infections. Many ball dahlias, such as ‘Jowey Winnie’ and ‘Downham Royal’ excel in these conditions, offering both beauty and practicality.
Understand Growth Habits
The way a dahlia grows can impact how it fits into your garden.
-
Compact or dwarf varieties - Perfect for containers or small gardens, these stay neat and manageable.
- Tall - Ideal as focal points or back-of-border plants, though they may need staking for support.
Start with Quality Tubers
Healthy tubers are the foundation of a successful dahlia season. Source from reputable growers to ensure you’re getting high-quality stock. Heirloom varieties offer unique charm, while modern hybrids often boast improved resilience and performance.
Experiment and Learn
Part of the joy of growing dahlias is finding what works best for you. Experiment with a few new varieties each year, and keep notes on how they perform in your conditions. Over time, you’ll develop a collection that reflects your preferences and environment.
Trust Your Instincts
At the end of the day, grow what you love. Whether it’s the creamy, romantic blooms of ‘Café au Lait’ or the bold energy of a fiery orange variety, your personal connection to a flower is what makes it special.
Endless Possibilities
Dahlias offer something for everyone, whether you’re a seasoned grower or just getting started. By blending practical considerations with personal taste, you can create a garden or business full of beauty and joy. Happy planting!
