Introduction
There is nothing quite like the excitement of seeing your first dinnerplate dahlias of the season begin to unfurl its petals. These spectacular flowers are famous for their incredible variety of shapes and colors, making them a favorite for gardeners who want high-impact blooms from midsummer through the first frost. Whether you are looking for dinnerplate-sized blossoms or charming little pompons, finding the right source for your plants is the essential first step toward a successful growing season.
At Longfield Gardens, we enjoy helping gardeners discover the perfect varieties to match their style and local conditions. This guide is designed to help you navigate your options, from browsing our dahlia collection to visiting your neighborhood nursery. We will cover what to look for in a healthy plant, the best time to start shopping, and how to ensure you are getting the best value for your garden.
By understanding where to buy dahlia plants and tubers, you can make informed choices that lead to a vibrant, flower-filled landscape all summer long. Choosing a reliable source ensures that you receive healthy, vigorous plants that are ready to thrive in your garden. If you are not sure when to plant, start by checking your USDA hardiness zone map.
Online vs. Local: Where to Find Your Dahlias
When you start searching for dahlias, you will quickly notice that they are available in two primary forms: dormant tubers and actively growing potted plants. Your choice of where to shop often depends on which of these forms you prefer. Both options have their benefits, and many gardeners find that a combination of both works best for their needs.
Buying Dahlias Online
The most popular way to purchase dahlias is through online retailers. When you shop online, you are typically buying dahlia tubers. These are the thick, underground storage roots of the plant. They look a bit like a bunch of small potatoes or carrots and are the most efficient way to ship dahlias over long distances.
Shopping online offers the widest possible selection of varieties. While a local store might carry five or ten different types, online catalogs often feature hundreds of options. You can filter by height, color, bloom size, and even flower shape, including single dahlias. This makes it easy to find a specific variety you may have seen in a magazine or at a flower show.
We take great care to ensure that our tubers are healthy and true to their variety names. When you order online, you can often place your order during the winter months to reserve your favorite colors before they sell out. The tubers are then shipped directly to your door at the ideal time for planting in your specific climate. For a broader look at the range of plants we carry, browse our curated dahlia collections.
Buying Dahlias at Local Garden Centers
If you prefer to see a green plant before you buy it, local garden centers and nurseries are excellent resources. In the late spring and early summer, these shops often sell dahlias that have already been started in pots. These are "ready-to-go" plants that already have leaves and sometimes even a few early flower buds.
Buying locally offers instant gratification. You don’t have to wait for a shipment or wait for a tuber to sprout. It is also a great way to support businesses in your community. However, keep in mind that local shops usually have a more limited selection. They tend to carry the most popular or "proven" varieties that grow well in your general area.
Specialized Flower Farms and Societies
For those looking for rare or exhibition-quality varieties, specialized flower farms and local dahlia societies are wonderful places to explore. These sources are often run by enthusiasts who have a deep passion for the genus. Many flower farms hold tuber sales in the spring, and dahlia societies often host plant sales where members share divisions from their own prize-winning collections. These sales are great opportunities to find unique varieties that you won’t see in big-box stores.
What to do next:
- Decide if you want the massive variety found online or the "ready-to-plant" convenience of a local nursery.
- Check your USDA hardiness zone so you know when it is safe to plant.
- Make a list of your favorite colors and flower shapes to help narrow down your choices.
Choosing the Right Dahlia Types for Your Garden
Before you finalize your purchase, it helps to know which types of dahlias will work best for your space. Dahlias are classified by the shape and size of their blooms. Knowing these categories makes it much easier to shop for exactly what you need.
Dinnerplate Dahlias
If you want flowers that make people stop and stare, dinnerplate dahlias are the way to go. These varieties produce massive blooms that can reach 8 to 12 inches in diameter. Because the flowers are so large and heavy, these plants usually require sturdy staking to keep the stems from snapping. They are perfect for the back of a flower border where their height and size can be fully appreciated.
Decorative and Ball Dahlias
Decorative dahlias are perhaps the most versatile. They have broad, flat-tipped petals and come in a vast array of colors. Ball and Pompon dahlias have a more structured, spherical shape with petals that curve inward. These types are incredibly popular for cutting because their blooms are very durable and look beautiful in vases. If you enjoy making floral arrangements, PomPon dahlias are excellent choices to add to your shopping list.
Cactus and Semi-Cactus Dahlias
For a more exotic look, consider cactus dahlias. Their petals are long and narrow, often curving or spiking outward, giving the flower a "spiny" appearance. They add a wonderful texture to the garden and are often more resistant to heavy rain because water slips through the narrow petals rather than weighing the flower down.
Border and Gallery Dahlias
Not every dahlia needs to be a giant. If you have a small garden or prefer to grow flowers in containers, look for border dahlias. These plants stay compact, usually reaching only 12 to 18 inches in height. They produce plenty of flowers but don't require the heavy staking that taller varieties need. They are a great "low-maintenance" entry point for new gardeners.
How to Spot High-Quality Dahlia Tubers and Plants
Regardless of where you choose to buy your dahlias, quality is the most important factor for success. Healthy starting material leads to vigorous plants and more flowers. Here is what to look for when you are evaluating your purchase.
Inspecting Tubers
If you are buying tubers in a store or receiving them in the mail, they should feel firm to the touch, similar to a fresh potato. It is normal for them to have a little bit of surface dust or peat moss on them, but they should not feel mushy or hollow.
The most important part of a dahlia tuber is the "eye." This is the small bump or growing point located on the neck of the tuber, where it connects to the old stem. In early spring, the eye might be hard to see, but as it gets closer to planting time, it may begin to sprout a tiny green or pink shoot. A tuber must have at least one viable eye to grow into a plant.
Evaluating Potted Plants
When shopping for potted dahlias at a nursery, look for plants with deep green, healthy foliage. Avoid plants that have yellowing leaves or signs of pests like aphids or spider mites. Check the bottom of the pot to see if roots are growing out of the drainage holes; while a few roots are fine, a plant that is extremely "root-bound" may take longer to establish itself in your garden soil.
The Importance of Variety Labeling
Trustworthy sellers will always clearly label their dahlias with the variety name. This is important because different varieties have different heights and bloom times. Knowing exactly what you are buying allows you to plan your garden layout effectively. If a seller only labels plants by color (e.g., "Pink Dahlia"), you won't know if that plant will grow to be two feet tall or five feet tall. For a broader overview of dahlia planting and care, see our All About Dahlias guide.
Key Takeaway: High-quality dahlias should be firm and well-labeled. Whether you are buying a dormant tuber or a green plant, starting with healthy stock is the best way to ensure a summer full of blooms.
The Best Time to Buy Dahlias
Timing is everything when it comes to gardening. Because dahlias are warm-weather plants, the window for buying them is closely tied to the seasons.
Winter and Early Spring (January - March)
This is the best time to shop online. Many retailers open their stores for pre-orders during these months. Even though it is too cold to plant, buying early ensures you get the specific varieties you want before they sell out. Most online sellers, including us at Longfield Gardens, will hold your order and ship it once the weather in your area is warm enough for safe transport. You can find the details on our shipping information page.
Mid to Late Spring (April - May)
This is the peak time for buying dahlia tubers in retail stores and for seeing the first potted plants arrive at garden centers. If you live in a region with a short growing season, this is also a good time to "pre-start" your tubers indoors in pots. This gives the plants a head start so they begin blooming earlier in the summer.
Early Summer (June)
By June, most gardeners have already planted their dahlias, but you can still find potted plants at nurseries. This is a great time to pick up a few extra plants to fill in any gaps in your flower beds. Dahlias planted in June will still have plenty of time to grow and bloom before the autumn frost.
What to Expect When Your Dahlias Arrive
If you choose to buy your dahlias online, receiving your package is an exciting moment. Understanding the shipping process helps set realistic expectations for your gardening journey.
Most dahlia tubers are shipped in bags filled with peat moss or vermiculite. This material helps regulate moisture and protects the tubers during transit. When you open your package, do not be alarmed if the tubers look a bit "shriveled" or dusty. As long as they are firm and have a visible eye or the potential for one, they are healthy and ready to grow.
At Longfield Gardens, we time our shipments based on your USDA hardiness zone. We typically aim to have your tubers arrive about two weeks before the ideal planting time for your area. This ensures the tubers don't sit in a cold warehouse or a hot delivery truck for too long.
When your tubers arrive, it is a good idea to open the bags and check them. If you aren't ready to plant immediately, store them in a cool, dark, and dry place. A basement or a cool closet works well. Avoid spots that are too humid, which can cause rot, or too dry, which can cause the tubers to wither.
Why Quality and Service Matter
When you are deciding where to buy your plants, consider the support and guarantees offered by the seller. Gardening is a rewarding hobby, but nature can sometimes be unpredictable. Choosing a supplier that stands behind their products adds an extra layer of confidence to your experience.
We provide a 100% quality guarantee on our items. This means we ensure that your dahlias arrive in prime condition and are true to the variety you ordered. If you encounter a problem with the quality or performance of your plants during their first growing season, we are here to help with replacements or credits.
Beyond the plants themselves, look for a source that provides practical advice. A good seller wants you to succeed and will offer guides on planting depth, spacing, and care. This support is especially helpful for beginners who are just starting their first dahlia garden.
What to do next:
- Open your dahlia package as soon as it arrives to inspect the tubers.
- Store them in a cool, dark place if you aren't planting them the same day.
- Review the planting instructions provided by the seller to get off to a great start.
Planning Your Dahlia Garden Layout
Once you know where you are buying your plants, the next step is planning where they will go. This stage of the process is where your creativity can really shine. Thinking about height, color, and sunlight will help you get the most out of your purchase.
Sunlight and Drainage
Regardless of where you bought your dahlias, they all have the same basic needs. They thrive in full sun, which means at least six to eight hours of direct sunlight every day. They also need well-draining soil. "Drainage" simply refers to how quickly water moves through the soil. Dahlias do not like to have "wet feet," so avoid planting them in low spots where water puddles after a rainstorm.
Spacing for Success
It is tempting to plant your dahlias close together to create a dense wall of color, but they need room to breathe. Proper spacing allows for good air circulation, which helps keep the plants healthy and prevents issues like powdery mildew. If you want more detail, see how far apart to grow dahlias.
- Large varieties: Space them about 2 to 3 feet apart.
- Medium varieties: Space them about 1.5 to 2 feet apart.
- Small/Border varieties: Space them about 12 inches apart.
Staking and Support
If you have purchased tall decorative or dinnerplate varieties, plan for support early. It is much easier to put a stake in the ground at the time of planting than it is to try and support a five-foot-tall plant that is already leaning. Wooden stakes, bamboo poles, or sturdy tomato cages all work well to keep your dahlias upright and looking their best. For step-by-step help, read how to stake dahlia tubers.
Success Is Just a Choice Away
Finding the best place to buy dahlia plants is the first step in a journey that ends with a garden full of stunning, colorful blooms. Whether you choose the vast variety of an online catalog or the convenience of a local nursery, focusing on quality and variety will lead to a more rewarding experience.
Remember that gardening is meant to be an enjoyable and accessible activity. Don't feel pressured to get everything perfect in your first year. Part of the fun is trying new colors and shapes each season to see what works best in your unique space. With a little bit of planning and a reliable source for your plants, you will be well on your way to a spectacular summer display.

FAQ
When is the best time to buy dahlia tubers?
The best time to buy dahlia tubers online is during the winter and early spring, typically from January through March. This is when the selection is at its peak and you can reserve popular varieties before they sell out. If you prefer buying potted plants locally, wait until late spring when the threat of frost has passed in your area.
Should I buy dahlia tubers or potted plants?
Both are great options depending on your goals. Tubers are generally less expensive and offer a much wider variety of colors and shapes, especially when shopping online. Potted plants are ideal if you want a head start on the season or want to see the foliage before you buy, but they are usually only available locally and in limited varieties.
How can I tell if a dahlia tuber is healthy?
A healthy dahlia tuber should feel firm and plump, similar to a fresh root vegetable. Look for a visible "eye" or a small sprout near the neck of the tuber. Avoid any tubers that feel mushy, hollow, or excessively shriveled, as these may not have enough stored energy to sprout successfully.
Does Longfield Gardens ship dahlias to my state?
We ship dahlia tubers to the 48 contiguous United States. Due to agricultural regulations and shipping constraints, we do not ship to Hawaii, Alaska, or US Territories. Our shipments are timed to arrive approximately two weeks before the ideal planting time for your specific USDA hardiness zone.
