Flower seeds sown in fall should be winter hardy for your climate and planted six to eight weeks before the first hard frost in the area. In mild climates, these resulting plants will bloom in the late fall and winter. Consider planting anemone vitifolia, lobelia erinus, Shasta daisies, coreopsis, viola wittockian, gaillardia aristata, rudbeckia figida, salvia sylvestris, lobularia maritima, sedum, campanula, or physalis alkengi.
The key to successfully growing fall vegetables is to time the planting to allow the maturation process to complete before the first hard frost in your area, if applicable. This provides you with healthy fresh vegetables and keeps your garden soil performing well during the fall and winter. Some fall vegetable seeds to plant that require 60 days to reach maturity include early carrots, leeks, turnips, kohlrabi, cabbages, winter cauliflower, collards, perennial herbs, and swiss chard. Vegetable seed crops that are early maturing and ready for harvest in approximately 30 days include chives, bunching onions, radishes, broccoli, leaf lettuces, mustard, and spinach.
