Sowing Some Flower Seeds
Fall usually isn't the time in most parts of the country to sow seeds, but there are some flowers that need sowing now so you'll have flowers next year. Botanically speaking, these are called biennials. Biennials grow only foliage their first year. After a dormant period in winter, they start growing in spring to form a flower. Some common biennial flowers in the flower garden include foxgloves, hollyhocks, and sweet William (Dianthus). Even some vegetables, such as carrots and parsley, are considered biennials. If you happen to leave a carrot in the ground and it survives until spring, you'll see it will bolt, or form a flower stalk, as soon as the weather warms.
Growing Biennials
You can have two approaches to growing biennials; let nature take its course or help nature along. Biennial flowers love to form seeds. Leave spent flowers on the plant and you'll see soon afterward seed pods will form. When they dry they disperse seeds all around. These seeds naturally germinate in the warm soil and start growing. If you look under some of your favorite perernnial and biennial plants, you may discover some young seedlings of these self-sown flowers. If you'd like to have your biennials in another part of the garden, try collecting seed and sowing them yourself. Once the seed pods dry you can collect the seed and spread it in a new area. You don't have to create a fine seed bed. Just scratch up some of the soil and sprinkle the seeds. With a little water, they will grow on their own.
Too Many Flowers
The only problem you may have is too many seedlings. In fall or spring, thin out the self-sown seedling patch to provide proper plant spacing. Too many plants will result in smaller plants and fewer flowers in summer.
Remove the flower stalks of your biennials once the seeds are removed or dropped. Don't worry about protecting the young seedlings in winter. They are tough and adapted to your climate. Come spring they will continue to grow and provide beautiful flowers for you to enjoy.
