That does seem unusual for zone 6. Which perennials do you have sown? Those can vary in their germination times. And, what kind of weather have you been having? And, are the containers in sun, shade, or mixed light? And, when did you sow them and where did you get your seeds? Is this your first year wintersowing? We can't have our newbies feeling frustrated. Hang in there. I promise it works!
