Mary Ann King of Pine Ridge Gardens Reveals Perennial Wildflower Seed Tips

The bare spots in your fall garden could be the ideal place to put in a few seeds for next spring.

Even though they may not come up before the first frost, they will emerge by spring. In particular, seeds that need a cold period in order to sprout will wait until the soil warms next year. If seedlings do come up, plan to mulch them after the first freeze.

Native plants have the advantage of easily adapting to our soil and weather, as well as being beneficial for wildlife.

Experienced gardener and native plant specialist, Mary Ann King, is the owner of Pine Ridge Gardens in London, Ark. King grows hundreds of native plant species from seed each year.

"I try to grow the plants that gardeners can't find other places," King said. "After all these years, I am still learning how to grow some things. It is frustrating when what grows is not what you thought it would be. And some seeds won’t grow at all."

King said that some tree seeds and perennials such as native clematis can take two years to come up.

"Home gardeners can select from a wide variety of easy to grow natives," King said. "Most perennials take four to six weeks to germinate; some take three or four months."

Since it is difficult to control conditions in a flower bed, it is best to plant seeds in containers.

King said to plant seeds in seed germination mix, available from garden supply stores. Look for ProMix, Scotts TX-366 or Redi- Earth. Avoid planting seeds too deep. Most seeds should just be barely covered with tiny seeds scattered on top of the medium.

King suggested some native plants that you can to grow at home from seed.
