This plant’s tubers were an important food source for western tribes of Native Americans. Found from southern Canada south to North Carolina, Kentucky and Texas, this plant tolerates full to partial sun, dry to moderate moisture, and a wide range of soils. It blooms from late August to October and flowers attract honey bees and wild bees. Serves as an important wildlife plant – deer forage on leaves and birds eat the seeds. A way to insure germination is to cold stratify perennial seeds. Stratification. This is the most common way to break your seeds out of dormancy. Essentially, you are simulating a short winter for the seed by placing it in the refrigerator. Most seeds carry inhibitors that prevent them from germinating until warmer temperatures arrive in the spring. When the plant goes back to room temperature after being placed in the refrigerator, it is more likely to undergo germination. The length of the stratification process depends on your specific seed. Larger seeds often need to be placed in between wet paper towels before going into the refrigerator. For your smaller seeds, you’ll want to place them in a tray of soil. Add Light. Some seeds need sunlight to begin to germinate. Place your seeds on top of your soil for a few days and have a little bit of patience while expecting them to begin to germinate.
