at least 30 seeds To successfully sow autumn primrose from seed, sow in autumn or late winter in pots or directly outdoors in well-drained soil. Make sure the soil is moist and remove weeds to reduce competition. The seeds need a cold period (stratification) to germinate in spring, so leave them outdoors over winter. Keep in mind that: Seeds sown in autumn will germinate in early spring when light and warmth return. Choose a location with full sunlight when planting your autumn primroses. Autumn primroses grow best in an environment with plenty of sunshine and moderate temperatures.
