Most native plants benefit from a winter cycle to help break seed dormancy and trigger germination. In nature, seeds often disperse or fall to the ground at the end of the growing season. When spring arrives, those that land in the right conditions, with good seed-to-soil contact, germinate and begin to grow.
While this natural process works, it isn't particularly reliable, and germination rates can be low. Thousands of seeds may fall, but only a small percentage will successfully germinate and survive. That's why I don't recommend simply scattering seeds on the ground and expecting them all to sprout in the spring. You also have to consider the elements, such as wind and rain washing seeds away, as well as hungry critters looking for a tasty snack! So don't waste those precious seeds!
What got me into growing large quantities of native plants was winter sowing. This method involves creating a mini greenhouse using containers that are left outdoors throughout the winter. The seeds experience natural winter conditions, while the container provides a protected environment for germination when spring arrives.
Almost any container will work, provided it has drainage holes and enough depth for at least three inches of soil. I recommend using plain potting soil. Nothing fancy is needed, but avoid garden soil, which can contain w**d seeds that may be difficult to distinguish from your native seedlings.
Place your containers in a partially shaded spot for the winter. As spring approaches, move them somewhere warmer with access to sunlight, preferably morning sun, and keep the soil moist while you wait for germination. Once the seedlings emerge, pay closer attention to their sun exposure. Strong, hot sunlight can scorch and kill tender seedlings, so finding the right balance is important.
Once enough seedlings have sprouted, begin opening the containers to gradually acclimatize them to the sun and wind. You can eventually remove the lids altogether, but keep an eye on the weather and protect the seedlings from overnight frost and heavy rain.
You'll know your seedlings are getting ready for transplanting when they're around two to three inches tall and have healthy green growth. However, don't worry if some seeds haven't sprouted by the time the last frost date arrives. Some native plants simply take their time! Milkw**d, for example, can be slow to emerge, sometimes waiting until mid-spring before making an appearance. Be patient, keep the soil moist, and give those containers a little more time. You might be surprised by what eventually pops up!
