Autumn Sown Hardy annuals

I lost loads of stuff in the greenhouse in December so I am being more cautious this year. The cornflowers are one of the only things that survived, even lots of the sweet peas conked out.

I lost all my cornflower and sweetpeas... my anemones outside froze and then all rotted

I don’t grow anemones, Scarlet.
is it too late to start again with those?

I was tempted to buy more in late Dec - but I thought they may recover? Unfortunately i dug a couple of the corms out this week and the top of the corms are rotted away.
I could maybe start some more - but its still so cold, I actually placed an order today...and they were sold out
