As nutculet says seed sowing can be a bit hit and miss. I've had a poor run of germination this year but a lot were old seeds needing to be sown this year and with hinde sight were probably stored in too warm a place.
Some biennials are fine in the ground over winter providing they have a good root system and are planted out in plenty of time to establish themselves before the first frost and snow hit them - Bellis, Foxglove, Sweet William and parsley have all come through the winter in my garden ,sown in July and planted out September/ October time.
Sweet Pea and Cornflower prefer being in an unheated GH.
Later in the year I was going to sow, Lupin, Hollyhock and Wallflowers for next year.
Which biennials were you thinking of growing.
