15 seeds Sowing: The seeds can be sown directly on the growing site or in pots. Since it is a perennial (multi-year) plant, the seeds may need a cold period to germinate (stratification), which means that autumn sowing is often successful. Time: They spread themselves, so you can imitate nature by sowing the seeds directly when they have matured. Placement: They thrive in most locations but like to spread in nutrient-rich soil. Things to consider: It takes longer to get flowering plants from seed compared to dividing the bulb. Evening primrose can spread greatly over time in the garden. They are related to star onions and alliums.
