~ Germination instructions ~
First, soak to seeds for 24 hours to soften the outer seed coating. Viola sororia seeds require cold stratification to coax the seeds out of dormancy. Cold stratification is achieved by scattering the seeds on the surface of the planting medium, barely covering them with a sprinkling of moist soil and placing them in the fridge for one month to six weeks. Containers are then moved to an area where the soil will remain between 45 to 55 degrees Fahrenheit.
