2025 - What I sowed today

I sowed a variety of hardy flowers, but maybe not quite at the right time 

Coreopsis Early Sunrise
Lupin Festival mixed, Russell mixed
Leucanthemum Crazy Daisy
Pansy Gaiant Fancy mixed
Wallflower Fire King, Cloth of Gold, Persian Carpet, Tomb Thumb
Delphinium Pacific Giants, Avalon
Foxglove Foxy mixed

I've yet to go through all the seed swap flowers to see what I can sow.

Put Aquilegia seed packets in fridge to stratify.  Is this adequate or do th seeds actually have to be in the soil and moist in the cold?
