Best windowsill direction for cuttings?

Trying lupin basal cuttings for the first time. I’ve read they need a good amount of sun to make energy, but not direct sun. I have a choice between:
1.  NNE facing windowsill that only gets direct sun until 10am-ish.
2.  SSW facing windowsill which gets partial sun most of day. The sun is so low this time of year it has to fight through the half dead laylandii trees at the end of the garden.

I’ve not had much success with wallflower cutting on either windowsill. Hoping for better this time!

    Lupin in barely frost free green house here. Kitchen window sill north facing,gets no sun,but plenty of light,as we're unoverlooked. They don't need sun, just light and a bit of warmth.

    NNE is better. Light not heat as already said. You'd have to be careful if you have heating on as well and there's a radiator at that window.
    If the other one is shaded enough, it might be ok, but you'd have to be vigilant. Even at this time of year, a bit of sun can raise temps enormously, and cuttings can fry.
    It's a place where beautiful isn't enough of a word....

    I live in west central Scotland - not where that photo is...

    The perennial wallflower, Bowle's mauve will root easily in a glass of water. I haven't tried this with the biennial ones, but they grow easily from seed sown in late spring.

    Thank you all!

    Have moved them to south facing window. There is a radiator but it’s rarely in these days given the energy price rise.

    @Buttercupdays, thank you! My one very precious Bowle's mauve plant is getting very leggy and I have had 3 unsuccessful attempts in perlite and soil. Will try water right now :)
