Meadowsweet is a fantastic herb that greatly benefits from stratification, which helps break the dormancy of its seeds. You can do this in a couple of ways: one option is to sow the seeds directly outdoors in the autumn, which works well if you have a good amount of seeds. The other option is to cold-moist stratify them for about 3-4 weeks before planting indoors in the spring, which is likely to be more reliable if you're working with fewer seeds.

Ensure the seeds are sown on the surface, as they require light to germinate, and keep the soil consistently moist. From my experience, stratified meadowsweet generally germinates within a couple of weeks.

Once the seedlings develop their true leaves, pot them up and plant them out when they reach a height of around 4-6 inches. This herb thrives in damp conditions, making it particularly well-suited for heavy clay soils, but it can also adapt to most soil types. It does well in full sun or partial shade and has a knack for holding its own against weeds – perfect for those less managed spots in your garden.
