Fall Planting For Best Results
Most native wildflower seeds need to go through a natural process called “Cold Moist Stratification” or CMS for short in order to successfully germinate.
CMS aids in breaking down the seed coat and signaling it to come out of dormancy. Essentially it is a set of conditions which enables this to happen. Cold, moist soil occurs naturally over the winter months ( in our part of the world) along with temperature fluctuations.
This makes the late fall a great time to plant native wildflower seeds – just before the winter, when CMS occurs.
Planting Depth & Location
Every wildflower species has a natural preference for soil coverage when germinating along with a preference for the amount of sunlight provided by the planting location. Below is a listing of the individual preferences of the species embedded in your handmade bookmark. Simply match the preferences and secure your bookmark (so it doesn’t blow away) seed side up atop a non-compacted area of your choice.
Common Milkweed (Asclepias syriaca)………..1/4” soil coverage, sunny location
Anise Hyssop (Agastache foeniculum)………….no cover, sunny location
Wild Quinine (Parthenium integrifolium)……..1/8” soil coverage, sunny location
Gallardia (Gallardia aristata) ……………..no cover, sun to part sun location
Nodding Onion (Allium cernuum)…….1/4” soil cover, part sun to sun
Prairie Smoke (Geum triflorum) …… 1/8” soil cover, sun to part sun
