Finding the perfect dahlia tubers is the first step toward a garden filled with spectacular, jewel-toned blooms that last from midsummer until the first frost.

At Longfield Gardens, we know that starting with healthy, vigorous tubers is the most important part of the process. This guide is for any gardener, from the first-timer to the seasoned pro, who wants to know exactly where to find the best plants for their space. We will cover the different types of retailers, what to look for in a healthy tuber, and how to time your purchase for the best results. By the end of this article, you will feel confident choosing the right sources to build your dream dahlia collection.
The Best Places to Buy Dahlia Tubers
When you start searching for where to get dahlia tubers, you will find several different options. Each source has its own set of benefits, depending on whether you value variety, convenience, or the ability to see the tubers in person before buying.
Online Retailers and Specialists
Online retailers are often the most popular choice for home gardeners because they offer the widest selection. When you shop online, you can browse hundreds of varieties that you simply won't find in a local shop. Most online companies, including us at Longfield Gardens, work directly with expert growers in regions like Holland to ensure the tubers are high quality and true to their variety name.
For example, Longfield Gardens offers Cafe Au Lait for gardeners who love a classic dinnerplate bloom.
The main advantage of online shopping is the ability to plan your garden well in advance. Most online stores open their pre-orders in late winter or early spring. This allows you to claim your favorite colors and shapes before they sell out. The tubers are then kept in climate-controlled storage and shipped to you exactly when it is time to plant in your specific area.
Local Independent Nurseries
Visiting a local garden center is a wonderful way to support businesses in your community. These shops often carry a curated selection of dahlias that are known to grow well in your local climate. The staff at independent nurseries are usually very knowledgeable and can offer advice on which varieties have performed best in nearby gardens.
The benefit of buying locally is that you can physically inspect the tubers. You can look for firm, plump tubers and check for visible "eyes" or early sprouts. However, keep in mind that local shops have limited shelf space, so the variety may be much smaller than what you find online.
Big Box Stores and Home Centers
Large home improvement stores often carry dahlia tubers in their seasonal garden aisles. These are usually the most budget-friendly options and are very convenient if you are already out running errands. They typically sell tubers in pre-packaged bags with colorful labels.
While these are great for a quick garden addition, the selection is usually limited to the most common varieties. If you are looking for a specific, rare dahlia or a particular award-winning cultivar, a specialist retailer is a more reliable bet.
Flower Farms and Collector Societies
For those looking for rare or "boutique" varieties, local flower farms and dahlia societies are excellent resources. Many small-scale flower farmers sell their surplus tubers in the spring. These are often varieties chosen specifically for their beauty as cut flowers.
Dahlia societies often hold tuber sales or swaps. This is a fantastic way to meet other enthusiasts and find unique plants that have been lovingly cared for by hobbyists. It is a more community-focused way to expand your garden.
Key Takeaway: For the best selection and the convenience of home delivery, online retailers are the top choice. For a hands-on experience and local advice, check your neighborhood nurseries.
What to Look for When Buying Dahlias
No matter where you choose to shop, knowing how to spot a good tuber will help you get the best results. A dahlia tuber is a starch-filled root that holds the energy the plant needs to start growing in the spring.
Identifying a Healthy Tuber
A healthy tuber should feel firm, much like a fresh potato. It should not feel mushy, hollow, or brittle. While some surface wrinkling is normal—as the tuber loses a little moisture during storage—it should still have some "give" without crumbling.
Don't worry if the tuber looks a bit dusty or has some dried soil on it. This is perfectly normal. What you want to avoid are tubers that show signs of mold or significant soft spots. If you are buying in person, give the tuber a gentle squeeze to ensure it is solid. For a closer look at tuber structure, see Dahlia Tubers: What You Need to Know.
Understanding the "Eye"
The "eye" is the most important part of a dahlia tuber. This is the small bump or growth point located at the "neck" of the tuber, where it connects to the old stem. This is where the new sprout will emerge.
If you are buying early in the season, the eyes might be "sleeping" and hard to see. As the weather warms up, they become more prominent and may even start to show a tiny green or pink sprout. A tuber without an eye will not grow, so reputable sellers ensure that every tuber or clump they ship has at least one viable eye.
Size and Shape Variations
Dahlia tubers come in all shapes and sizes. Some varieties produce large, thick tubers, while others produce long, skinny ones. The size of the tuber does not necessarily dictate the size of the flower. A small, healthy tuber from a "Dinnerplate" variety will still produce massive blooms, while a huge tuber from a "Pompon" variety will still produce small, round flowers.
Focus on the health and firmness of the tuber rather than its physical size. As long as there is a healthy neck and a visible eye, the plant has everything it needs to thrive.
Choosing Varieties Based on Your Garden Style
When you are deciding where to get dahlia tubers, it helps to know which types you are looking for. Dahlias are categorized by their flower shape and size.
Dinnerplate Dahlias
These are the giants of the dahlia world. Their blooms can reach 8 to 10 inches in diameter, or even larger. They make a massive statement in the back of a flower bed and are sure to be a conversation starter. Because the flowers are so heavy, these Dinnerplate Dahlias almost always need staking to keep the stems upright.
Decorative and Ball Dahlias
Decorative dahlias have broad, flat-tipped petals and come in a vast array of colors. Decorative dahlias are incredibly sturdy and are among the best choices for cut flower arrangements because they have a long vase life.
Cactus and Fimbriated Dahlias
If you want something unique, look for Cactus & Semi-Cactus Dahlias. They have long, narrow petals that roll inward, giving them a spiky, starburst appearance. Fimbriated varieties take this a step further with "fringed" petal tips that look like they have been snipped with scissors. These add wonderful texture to a garden border.
Border and Gallery Dahlias
Not every dahlia needs to be tall. If you have a small garden or want to grow flowers in containers, gallery dahlias produce a profusion of smaller blooms. They are excellent for the front of a flower bed or for adding color to a sunny patio.
What to Do Next:
- Decide where you want to plant your dahlias (containers vs. garden beds).
- Choose 2–3 different flower shapes to add visual interest.
- Look for a mix of colors that complement your existing landscape.
- Check the mature height of each variety to plan your spacing.
Timing Your Purchase for Success
Timing is everything when it comes to buying and planting dahlias. Because they are tropical plants native to Mexico and Central America, they love the heat and cannot tolerate frost.
When to Order
The best time to start looking for tubers is in January and February. This is when most online retailers, including us at Longfield Gardens, open their stores for the season. Ordering early ensures you get the varieties you want before they sell out. See our Shipping Information for more on how orders are timed by zone.
Even though you order in the winter, the tubers will not be shipped immediately. They are held in temperature-controlled warehouses until the weather in your area is safe for shipping. This prevents the tubers from freezing during transit.
Shipping and Arrival
We coordinate our shipping schedules based on USDA hardiness zones. This means your tubers will arrive about two weeks before the ideal planting time for your specific region. This gives you a little time to prepare your garden beds or gather your pots.
When your package arrives, open it immediately. Check the tubers to make sure they are firm and healthy. If you aren't ready to plant right away, keep them in a cool, dark, and dry place—like a basement or a garage—until the soil outside has warmed up.
Planting Windows
A simple rule of thumb is to plant your dahlia tubers around the same time you would plant your tomatoes. The soil needs to be warm, ideally around 60°F. In most parts of the United States, this happens between late April and early June. For a closer look at timing, see When Should I Plant Dahlia Tubers?.
If you plant them too early in cold, wet soil, the tubers may struggle to get started. Waiting for the right temperature leads to faster, healthier growth.
Why Source Quality Matters
It can be tempting to buy the cheapest tubers you find, but investing in quality stock pays off in the long run. High-quality tubers are more likely to be true to their variety. There is nothing more disappointing than waiting all summer for a "Cafe au Lait" dahlia only to have it bloom as a plain yellow flower.
At Longfield Gardens, we maintain a trial garden to evaluate how different varieties perform. This allows us to select only the best-performing plants for our customers. We also stand behind the quality of our plants with our 100% Quality Guarantee. Starting with healthy stock from a trusted source is the easiest way to ensure a successful growing season.
Sourcing for Different Garden Sizes
Where you get your tubers might also depend on how many you need.
Small Gardens and Patios
If you only have space for three or four plants, you might prefer to buy individual tubers from a local nursery or a specialty online shop. This allows you to pick a few "showstopper" varieties without having to buy in bulk. Look for varieties labeled "good for containers" if you are limited to a balcony or deck.
Large Landscapes and Cutting Gardens
If you are planning to fill a large border or want to grow enough flowers to make bouquets every week, look for retailers that offer "collections" or "mixes." These are often more economical and provide a coordinated color palette. We offer several curated dahlia collections that take the guesswork out of color matching.
Preparing for Your Delivery
Once you have decided where to get your dahlia tubers and placed your order, you can start getting ready for their arrival. Preparing ahead of time makes the planting process smooth and enjoyable.
- Choose a Sunny Spot: Dahlias need at least six to eight hours of direct sunlight every day to produce the most blooms.
- Check Your Soil Drainage: Dahlias like moisture, but they don't like to sit in soggy soil. If your soil is heavy clay, consider adding some compost to improve drainage.
- Gather Your Tools: You will need a simple trowel or a shovel. If you are planting tall varieties, have your stakes or cages ready to go at planting time.
- Clear the Area: Remove any weeds or debris from your planting site so the new sprouts don't have to compete for nutrients.
Key Takeaway: Preparation is the secret to a stress-free planting day. Having your site ready and your tools handy allows you to get your tubers in the ground quickly and correctly.
Conclusion
Finding where to get dahlia tubers is the start of a rewarding gardening adventure. Whether you choose the massive selection of an online retailer like Longfield Gardens or the local charm of a neighborhood nursery, the key is to look for firm, healthy tubers with visible eyes. By choosing a variety of shapes and sizes and timing your purchase with the spring warming, you set yourself up for a summer filled with incredible color.
- Shop online for the best variety and the convenience of zone-based shipping.

- Look for firm tubers with a healthy "eye" at the neck.
- Wait until the soil is warm and the threat of frost has passed before planting.
Gardening is one of the most rewarding ways to connect with nature and beautify your home. With a little planning and the right source for your plants, you can grow a dahlia garden that brings joy to you and your neighbors all season long.
FAQ
When is the best time to buy dahlia tubers?
The best time to buy is in late winter or early spring, typically between January and March. Most retailers open their pre-orders during this time, which gives you the best chance to secure popular varieties before they sell out for the season.
How do I know if a dahlia tuber is still good?
A healthy tuber should feel firm to the touch, similar to a fresh potato or a carrot. It should not be mushy, extremely shriveled, or show signs of rot. If you see a small bump or sprout near the neck (the eye), that is a great sign that the tuber is ready to grow.
Can I buy dahlia tubers in the fall?
Most retailers do not sell or ship dahlia tubers in the fall because they are frost-sensitive and difficult to ship during cold winter months. It is much better to buy them in the spring when they are ready to be planted and the weather is safe for transit.
Why should I buy from a specialist like Longfield Gardens?
Buying from a specialist ensures you receive high-quality tubers that are true to variety and have been stored in professional, climate-controlled conditions. We also provide support through planting guides and a quality guarantee, which gives you peace of mind as you start your garden.
