I'd sow them in a pot personally. they are more likely to germinate and grow to a reasonable size. you can then select the strongest ones to plant out.

Thank you. I think I will do that too. We have had such a mild winter this year here in Missouri that I will try my luck at a few direct sown on the south side of the house also. I don't know which varity is native here. I am anxious to try these from Europe. violets are my favorite!
