Wild Seed Project Cardinal Flower Seeds

Yes, cold stratification is essential for Cardinal flower seeds. They require a period of at least 60 days in temperatures below 40°F to break dormancy and germinate successfully.

While they are native to wetlands and streamsides, they will thrive in any garden bed as long as the soil remains consistently moist. They are not drought-tolerant and will struggle in dry, sandy, or well-draining soil.

Lobelia cardinalis is a short-lived perennial, meaning individual plants may only live for a few years. However, they are prolific reseeders, so if you leave the seed heads intact at the end of the season, you will likely see new plants emerge nearby each spring.

They are quite adaptable. You can plant them in full sun or partial shade, though they tend to bloom most vigorously when they receive at least some direct sunlight during the day.

The ideal window for sowing is between November and February. This timing allows the seeds to experience the necessary winter cold period naturally outdoors before they germinate in the spring.

Absolutely. The tubular shape and vibrant red color of the flowers are specifically evolved to attract hummingbirds, making this one of the most reliable plants for bringing them into your garden.
