I don't think Coleus seeds can stay viable in your zone. I wonder if you have shiso (Perilla?)
Shiso (Perilla frutescens)

yes,! I have that! Sorry, I thought of it as a type of coleus. I do though occasionally get a more fancy one pop up I guess from seeds,I do plant a few each spring, but normally just rebuy them as the fancy colored ones don't reseed easily for me, I assume they do for people in warmer winter areas. But some around the house pop up from time to time.
