Introduction
There is a unique kind of magic in watching a dahlia grow from a humble, potato-like tuber into a towering plant covered in intricate, colorful blooms. Whether you are dreaming of massive "dinnerplate" flowers the size of a dinner plate or perfectly symmetrical ball dahlias for your cutting garden, the excitement starts long before the first sprout appears. The journey to a spectacular summer display begins with finding a reliable source for your plants.
When you are deciding where to purchase dahlia tubers, the goal is to find high-quality stock that will thrive in your specific garden conditions. At Longfield Gardens, we focus on making this process as simple and rewarding as possible with our dahlia collections. We work closely with experienced growers to ensure you receive healthy tubers that are ready to perform.
In this guide, we will walk you through everything you need to know about sourcing dahlias. We’ll cover what to look for in a quality supplier, when to place your order, and how to choose the best varieties for your landscape. Finding the right source is the most important step in ensuring a season full of vibrant, healthy flowers.
Why the Source of Your Dahlia Tubers Matters
Choosing where to buy your dahlias is about more than just finding the lowest price. A dahlia tuber is a living energy cellar that contains everything the plant needs to get started. Because dahlias are not grown from seed in most home gardens, the health and "viability" of the tuber you purchase dictate the success of your entire season.
A reputable source provides tubers that are "true to name," meaning the flower that blooms in August will actually be the variety you chose in January. High-quality suppliers also ensure their stock is free from disease and has a visible "eye." This eye is the small growth point, similar to the eye on a potato, from which the main stem will emerge. Without a healthy eye, a tuber cannot grow, no matter how large or firm it looks.
By purchasing from specialists who understand the needs of home gardeners, you gain access to a wider range of colors and shapes than you might find at a local big-box store. We take pride in our selection process, trialing varieties in our own gardens to make sure they are vigorous and reliable before we offer them to you.
When to Start Shopping for Dahlia Tubers
Timing is everything when it comes to purchasing dahlias. While these plants don’t go into the ground until the soil is warm in late spring, the "shopping season" actually happens in the middle of winter.
Most online dahlia retailers, including our team here at Longfield Gardens, open their stores for pre-orders in early winter—typically between December and February. This is the best time to purchase because the most popular varieties, such as the creamy-pink Cafe au Lait, often sell out quickly.
The deep purple Thomas Edison can sell out quickly, too.
Key Takeaway: Start browsing dahlia catalogs in mid-winter. Pre-ordering early is the best way to secure rare or highly sought-after varieties before they are gone for the season.
How Shipping Cycles Work
Because dahlias are sensitive to freezing temperatures, they cannot be shipped during the height of winter. When you purchase from us, your shipping date is determined by your USDA hardiness zone. We time our deliveries so the tubers arrive about two weeks before your local planting time. This allows the tubers to arrive in prime condition, ready to be tucked into the warm spring soil.
What to Look for in a Quality Dahlia Tuber
If you are shopping in person or inspecting a shipment that just arrived, it helps to know what a "good" tuber looks like. Dahlia tubers come in all shapes and sizes depending on the variety. Some might be long and thin like a finger, while others are round and chunky like a small potato.
The size of the tuber does not determine the size of the flower. A small tuber from a vigorous variety will often outperform a giant tuber from a less hardy type. Instead of looking for size, look for these three signs of quality:
- Firmness: The tuber should feel solid, like a fresh carrot. It should not feel mushy, shriveled, or hollow.
- A Healthy Neck: The "neck" is the narrow part that connects the tuber to the old stem. This area must be intact, as this is where the eye is located.
- The Eye: Look for a small, slightly raised bump or a tiny green sprout near the neck. This is the sign that the tuber is alive and ready to grow.
It is worth noting that some tubers stay "dormant" longer than others. If you don't see a green sprout immediately upon delivery, don't worry. As long as the tuber is firm and the neck is intact, it will usually "wake up" once it feels the warmth of the soil.
Comparing Online Sources vs. Local Options
When deciding where to purchase dahlia tubers, you generally have three choices: online specialty retailers, local garden centers, or dahlia society sales. Each has its own benefits.
Online Specialty Retailers
Buying online is often the preferred choice for gardeners who want a specific look. We offer a curated selection of dahlias for sale that have been tested for performance. Online shopping allows you to filter by height, flower size, and color, making it much easier to plan a cohesive garden bed. Plus, the convenience of having your plants delivered at exactly the right time for your climate takes the guesswork out of the process.
Local Garden Centers
Local nurseries can be a great place to pick up standard dahlia varieties in the spring. You have the advantage of seeing the product before you buy it. However, the selection is usually much smaller than what you find online, and the tubers may have been sitting in a warm store for several weeks, which can cause them to dry out.
Dahlia Societies and Exchanges
If you have a local chapter of the American Dahlia Society in your area, they often hold tuber sales in the spring. These are excellent sources for "show-quality" dahlias. These sales are usually run by hobbyists who are passionate about specific varieties, though you often have to arrive very early to get the best items.
Selecting the Right Varieties for Your Garden
One of the joys of purchasing dahlia tubers is the incredible diversity of flower forms. Before you buy, think about how you want to use the flowers. This will help you narrow down where to purchase and which types to choose.
For Large, Dramatic Displays
If you want flowers that will stop traffic, look for Dinnerplate dahlias.
Varieties like Kelvin Floodlight (bright yellow) or Emory Paul (pinkish-purple) produce massive blooms that can reach 10 inches in diameter. These are perfect for the back of a garden border where they can tower over other plants.
For Cutting and Flower Arrangements
Ball dahlias have a tight, rounded structure that holds up exceptionally well after being cut.
PomPon dahlias are another excellent choice for cutting, as they were specifically bred for the floral industry to have long, sturdy stems and a long vase life.
For Pollinators and Borders
Single dahlias and "Mignon" types have open centers that make it easy for bees and butterflies to reach the nectar. These varieties are often shorter, making them a great choice for the front of a flower bed or for growing in containers on a patio.
What to Do Next:
- Measure your garden space to see how many dahlias you can fit (leave 18–24 inches between plants).
- Decide on a color palette—do you want bold "hot" colors or soft pastels?
- Check your USDA zone to see when your last frost date typically occurs.
- Place your pre-order early in the year to ensure variety availability.
Understanding the Buying and Shipping Process
When you purchase from Longfield Gardens, we aim to make the transaction as transparent as possible. Because we are shipping live plants, our process is a bit different than ordering a set of garden tools.
The Order Confirmation
Once you complete your purchase, you will receive an email confirmation. This is your receipt and your guarantee that your chosen varieties are reserved for you. We keep these tubers in a professional, temperature-controlled environment in our Lakewood, New Jersey facility until it is time to ship.
Tracking and Delivery
When the weather warms up and your shipping window opens, we carefully pack your tubers in breathable material to keep them safe during transit. You will receive a tracking number the moment your package is picked up by the carrier. We recommend opening your box as soon as it arrives to let the tubers breathe.
Our Quality Guarantee
We stand behind the quality of every plant we ship. Our 100% quality guarantee ensures that your items are true to variety and arrive in prime condition. If you notice any damage or quality issues upon delivery, we ask that you contact our customer service team promptly. We want you to feel confident that your investment in your garden is protected.
How to Handle Your Tubers After Purchase
Once you have decided where to purchase dahlia tubers and your order has arrived, there is often a short waiting period before they can go into the ground. Dahlias are tropical plants and cannot tolerate frost or cold, wet soil.
If your tubers arrive before the soil is at least 60°F, you can store them in a cool, dark, and dry place. A basement or a closet is usually perfect. Keep them in the packaging they arrived in, or place them in a box with some slightly damp peat moss or vermiculite to prevent them from drying out completely.
If you are eager to get a head start, you can "start" your tubers indoors in pots about 4 to 6 weeks before the last frost. This gives the plants a few weeks of growth in a protected environment, leading to earlier blooms once they are moved outside. This is a great "win" for gardeners in northern climates with shorter growing seasons.
Making Gardening Simple and Rewarding
Gardening shouldn't feel like a series of complicated rules and stressful decisions. Most of the success in growing dahlias comes from getting the basics right: starting with a healthy tuber, planting it in a sunny spot with good drainage, and waiting for the soil to warm up.
For more practical guidance, How to Grow Great Dahlias covers pinching, staking, and cutting blooms.

FAQ
When is the best time of year to buy dahlia tubers?
The best time to buy is during the winter months, typically from January through March. While you won't plant them until spring, most online retailers open their stores early so gardeners can reserve the most popular varieties before they sell out. Ordering early ensures you get the specific colors and shapes you want for your garden design.
Should I buy dahlia tubers online or at a local store?
Purchasing online generally offers a much larger selection of unique varieties and flower forms that aren't available in local shops. Additionally, reputable online suppliers like Longfield Gardens store tubers in professional, climate-controlled facilities until the exact right time for planting in your area. Local stores are convenient for last-minute purchases, but the selection is often limited to a few common types.
What should I look for to make sure a dahlia tuber is healthy?
A healthy tuber should feel firm to the touch, similar to a fresh potato or carrot. Avoid any that feel mushy, brittle, or shriveled. Most importantly, check for an "eye"—a small growth point or bump near the neck of the tuber. This eye is essential because it is the only place from which a new plant can grow.
How are dahlia tubers shipped, and will they survive the mail?
Dahlia tubers are quite hardy and travel well when packed correctly. We ship them in breathable packaging to prevent moisture buildup and time the shipments based on your USDA hardiness zone to avoid extreme cold. Once your package arrives, simply open it and store the tubers in a cool, dark place until your garden soil is warm enough for planting.
