Most wildflowers can (and should) be planted in the fall or early spring throughout many regions of the U.S. In the Southern and Western areas of the country the fall months of September through December are the most favorable time to plant wildflower seeds. In Northern and Northeastern regions seeds planted in the fall will remain dormant over the winter. Many varieties will quickly germinate in order to allow the seedling enough time to become established before going dormant for winter. Other varieties will just remain dormant within the soil until early spring. They will germinate and emerge in the spring when the conditions are favorable.
When you think about the life cycle of many flowers without man’s interference, they emerge in the spring, grow and flower summer to early fall, produce seeds which scatter to the winds and then the plant dies or goes dormant for the winter. The seeds remain in the cold winter ground yet to emerge once again in the spring. Almost all varieties of flowers, whether domesticated or wild, need periods of cold followed by a warming, such as freezing and thawing that naturally happens in the soil outside. This is called stratification, and keeps the seeds dormant for enough time to make it to the warm spring days to sprout.
When you receive our annual Heirloom Seed Catalog in late December of each year, many of the flower varieties would benefit from being planted in the fall instead of the spring. This year we are encouraging you to take a look at our Flower Department now and place your flower seed orders before the spring to benefit from the natural cycles. If you need specific information about what flowers would work in best in your area, email us your questions. Otherwise, if you are new to flower gardening, one of our flower mixes is a great place to start.
Here is a tip for successful flower seed planting this fall-
Do not plant your seeds too deeply, but try to broadcast them uniformly. Think about how the natural cycle works, with the seed heads drying out and shattering to release the seeds. They scatter onto the top of the soil and over time work their way into the proper position for germination. This can sometimes be achieved by mixing your seeds into a light soil mix and then spreading with a rake. Try not to cover the flower seeds deeper than 1/16 of an inch. If you live in an area with heavy bird pressures, you might have to use a floating row cover or cover slightly deeper to prevent bird predation. Or do as we sometimes do here and as the Native Americans have done; plant one for the birds, one for God and one for the farmer!
