Chrysanthemums, often simply called mums, are popular garden flowers celebrated for their vibrant autumn blooms. They add a welcome burst of color when many other garden species are fading for the season. While purchasing a potted plant is common, growing them from seed offers a wider selection of unique varieties and is a rewarding process for any gardener.
Where to Find Reputable Seed Vendors
Major online and mail-order seed companies offer unparalleled convenience and a vast inventory, often including unique or newly developed cultivars. When shopping online, vet the seller by checking for clear contact information and a detailed seed quality guarantee.
Local garden centers and nurseries provide geographically relevant advice, as staff can recommend varieties that thrive in the local climate. These shops may stock a narrower selection of seeds, frequently focusing on common annual types. Purchasing locally also allows you to physically inspect the packaging for signs of damage or poor storage conditions.
Specialized heirloom or rare seed banks are the primary source for unique or less common chrysanthemum species. These vendors focus on preserving genetic diversity, offering seeds that may not be available through mainstream channels. These specialty sources can provide the specific, unusual varieties that truly set a garden apart.
Understanding Chrysanthemum Seed Types
The complexity of buying chrysanthemum seeds stems from the fact that many large, showy florist mums are highly hybridized and propagated vegetatively from cuttings. These popular hybrid cultivars, often Chrysanthemum x morifolium, do not reliably produce seeds that grow true to the parent plant. Therefore, the seeds you purchase are typically from different, often less-hybridized, species.
Gardeners will most often encounter seeds for annual varieties, which are generally easier to grow and will bloom in the first year. These annuals are fast-growing and produce numerous, simple flowers. The seed packet should clearly list the specific botanical name, which is far more informative than a common name.
Perennial chrysanthemum seeds are available, but they may take longer to establish and sometimes require cold stratification before planting. Perennial garden mums are commonly listed under the Chrysanthemum x morifolium complex or the Chrysanthemum rubellum group, known for their hardiness. When selecting perennial seeds, check if the vendor has specified the plant’s USDA hardiness zone to ensure it will survive the winter in your region.
Key Factors for Ensuring Seed Viability
Regardless of the vendor chosen, the quality of the seeds themselves is paramount for a successful outcome. Always check the “packed for” date stamped on the seed packet, as this indicates the year the seeds were packaged for sale. Older seeds generally have a lower germination rate, making fresh stock preferable.
Reputable companies often provide a guaranteed germination rate, which is the percentage of seeds expected to sprout under ideal conditions. Seeds with a high stated rate, such as 70% or more, offer the best chance of success.
Proper storage of the seed stock is a major factor in maintaining viability before purchase. Seeds should be stored in a cool, dark, and dry environment, ideally between 32°F and 50°F.
If buying from a store, avoid packets displayed in direct sunlight or near sources of heat and humidity, as excessive warmth and moisture accelerate deterioration. Reading customer reviews specifically related to the vendor’s seed quality can provide insight into real-world germination success.
