to ATP!
I grow lisianthus and they are extremely slow growers. Here are some I planted in January. I do know that after they germinate, if you used a heat mat, take them off and let them in a cooler spot. Eventually they will get bigger. Mine bloom the same year. I had some over winter this past year as well.
Your first photo looks like a stray tomato seed got into the pot. Pretty healthy looking tomato seedling though.
