|When Should I Plant?
Wildflower planting dates largely depend on site location and geographic weather patterns. The planting timetable should be decided by seasonal precipitation in your area rather than by temperature. Wildflowers can be planted in the fall or early spring throughout all regions of the U.S.
SPRING SOWING: In the northern and northeastern geographic regions of the United States, USDA Zones 1 through 6, where extremely harsh winters are experienced, an early spring planting is recommended. In the Southern regions of the United States, USDA Zones 7 through 11, your wildflowers can also be sown in early spring, if desired.
NOTE: There are risks associated with an early spring planting in USDA Zones 1 through 11. Warm spring weather and adequate rainfall will accelerate germination and seedling growth. However, if rainfall is sporadic after initial germination followed by an extremely hot, dry period, supplemental watering may be required to keep the ground from drying out and the seedlings from dying.
NOTE: There are risks in sowing exotic garden varieties and "domesticated" species in the fall. Freeze damage may kill these varieties if unseasonably cold temperatures persist for long periods of time.
