There’s a plethora of wonderful herbs that we can grow for health, beauty, and overall wellness. Some offer several culinary uses, and many of them attract pollinators and other beneficial insects into our gardens. There are herbs for every gardener, and for the most part, herbs are forgiving and easy to grow. You might start your gardening journey with simple herbal starts, like peppermint and calendula, purchased from a local greenhouse. After a few seasons and a little more experience under your belt, you might feel inclined to heighten the experience and try growing herbs from seed. I think this is the most rewarding avenue—planting a tiny, precious seed and caring for the plant throughout its life until harvest. While most herbs are still easy to cultivate this way, there are a few plants that are considered a bit more advanced. These more advanced herbs might require cold stratification, scarification, or may be more finicky about climate.
This process mimics a cold winter by exposing the seeds to cold and damp conditions for a period of time. The timeline can vary depending on the seed, but most are cold stratified for 30-90 days, with 60 being the most common timeline for perennials.
This process includes nicking the seed coat to weaken the tough outer coat. This helps water better penetrate the seed.
