I've had some experience with columbine seeds and I think I can help. Columbine seeds can be a bit finicky, they typically require a period of cold stratification to germinate, which means you need to simulate winter conditions for them. You can try placing the seeds in a plastic bag with some moist soil and putting them in the fridge for about 3-4 weeks. After that, sow them in a seed starting mix and keep the soil moist but not waterlogged. They also prefer partial shade and cooler temperatures, so make sure you're providing the right environment for them to grow.
