CarnegieGarden Bleeding Heart Flower Seeds

Yes, Dicentra spectabilis seeds typically require cold stratification to break dormancy. You can achieve this by placing the seeds in a moist paper towel inside a sealed bag in your refrigerator for several weeks before sowing, which mimics the natural winter conditions they need to germinate.

These bleeding hearts are best suited for USDA hardiness zones 3–9. While they can handle the upper end of that range, they are woodland plants that prefer cooler temperatures and will struggle in regions with intense, prolonged summer heat.

They perform best in partial to full shade. While they can tolerate some morning sun, they require protection from harsh afternoon light, which can scorch their delicate foliage and cause the plants to go dormant earlier in the season.

Yes, bleeding hearts are generally considered deer-resistant. Their taste and texture are typically unappealing to deer, making them a reliable choice for woodland gardens or borders where wildlife pressure is a concern.

You can expect germination to take between 20 and 40 days. Because they are slow to start, patience and consistent moisture are key during the initial growing period.

No, these are reliable perennials. Once established, they will return year after year, typically blooming in the spring and early summer before naturally fading back as the weather warms.
