Yes, these seeds require a period of cold stratification to break dormancy and trigger germination. You will need to simulate winter conditions by placing the seeds in a moist medium in the refrigerator for several weeks before sowing them.

Bleeding hearts are cool-weather lovers and generally struggle in regions with intense summer heat. They are best suited for USDA zones 3-9, so if you are in a warmer zone, ensure they are planted in a deeply shaded, cool spot to prevent heat stress.

Bleeding hearts grown from seed typically take a bit of patience. While they establish their root systems in the first year, you should expect the most significant, recognizable heart-shaped blooms to appear in the second or third growing season.
