The dahlia is a diverse flowering plant, celebrated for its wide array of bloom sizes, colors, and petal formations, ranging from compact pompons to dinner-plate giants. Dahlias are purchased either as cut blooms for immediate display or as tubers and plants for cultivation in a garden setting. Understanding the different supply chains for each form is the first step in successfully acquiring the specific dahlia product desired. This guide details where to find both cut stems and planting tubers.
Sources for Cut Dahlia Blooms
The purchase of cut dahlia flowers relies heavily on local seasonal availability. Traditional florists and floral design studios are reliable sources, especially during the peak bloom period. They frequently source stems from regional farms, offering varieties bred for long, sturdy stems and durability in a vase.
For a more direct connection to the grower, local farmers’ markets and roadside flower stands are excellent options from late summer through the first frost. Growers often harvest the blooms fresh that morning. When selecting cut stems, ensure the flower head is nearly or fully open, as dahlia buds rarely open once severed from the plant.
Large grocery store floral departments also carry dahlias, though variety selection may be limited. For large quantities, specialized wholesale florists and online bulk flower companies offer cut stems, sometimes shipping them directly from the farm. Look for stems that are firm and hydrated, avoiding any signs of wilting or bruising.
Locating Local Retailers for Tubers and Plants
The most convenient way for the casual gardener to purchase dahlia planting material is through local retail locations. Large home improvement stores and national garden centers stock dahlia tubers in late winter and early spring. These mass-market retailers often carry popular, easy-to-grow varieties, usually sold in plastic bags or boxes containing dormant tubers.
Independent nurseries and local garden centers provide a more curated selection and often feature potted dahlia plants ready for planting after the danger of frost has passed. Purchasing a potted plant offers the advantage of seeing the foliage and sometimes a bloom, ensuring the correct variety has been selected. Staff at these stores may also provide region-specific planting and care advice.
Another local source is community garden clubs or regional dahlia society sales and auctions, which usually occur in the spring. These events feature tubers from members’ divided stock, often including unique or heirloom varieties not found in commercial stores. When purchasing dormant tubers, inspect them for firmness; they should not be shriveled or soft, and each tuber must possess at least one visible “eye” or growth point.
Specialty Mail-Order and Online Dahlia Suppliers
For gardeners seeking extensive variety, rare cultivars, or certified stock, specialized mail-order and online suppliers are the primary resource. These sources include dedicated dahlia farms, specialized bulb and tuber companies, and national online retailers. Ordering from these specialists provides access to thousands of named varieties, ensuring genetic purity and accurate labeling for specific colors and forms.
Dedicated dahlia farms often grow hundreds of varieties and are actively involved in hybridizing new cultivars, offering the newest stock. These small-scale growers typically open their online sales windows in late fall or early winter, often in December or January, to manage high demand. Gardeners must place pre-orders promptly, as popular varieties often sell out quickly.
Shipping logistics are a significant factor, as mail-order tubers are delicate and susceptible to freezing. Suppliers typically ship dormant tubers in the spring, usually from April to May, once the threat of harsh winter temperatures has passed. Upon arrival, tubers should be immediately inspected and stored in a cool, frost-free environment around 40 to 45 degrees Fahrenheit until soil temperatures are sufficiently warm for planting.
The Role of Seasonal Timing
The availability of dahlias is entirely dependent on seasonal timing, dictating whether to search for a bloom or a tuber. Cut dahlia flowers are a warm-weather product, with peak availability spanning the summer and fall months. The harvest season for fresh stems generally begins in mid-July and continues until the first hard frost, typically in October.
The window for purchasing dahlia tubers for planting is concentrated in late winter and early spring. The pre-ordering period for the widest selection from specialty growers begins as early as December or January. This early purchasing allows growers to plan stock and ensures customers secure desired varieties before they sell out.
Retail stores and garden centers stock tubers from approximately February through May, coinciding with the typical planting season. Searching for dormant tubers in the summer or fall is fruitless, as the plants will be actively growing and producing flowers during that time. Understanding this seasonal rhythm is necessary for acquiring the desired dahlia product at the correct time.
