This is Ipomoea alba a.k.a. Calonyction aculeatum a.k.a. Ipomoea
I nick them first, soak them overnight in a weak bleach solution,
and germinate them on kitchen roll dampened with that solution
in a small pot covered with cling film. The key is that they need
warm, humid conditions until they have their cotyledons open, but
are very prone to rotting if they get too wet or too cold, will not
manage to break the hard seed if too dry and don't like it too hot!
So I plant then as soon as a root starts to develop, and take care
until they get to that stage. Once they have got their cotyledons
open, they are rarely much trouble (except for red spider mite).
nick the bottom of the seed and let it soak overnight in water...I've
forgotten mine for day or two and sometimes find they've begun to
sprout in just that short time...works well with morning glory seeds
Here in Colorado (high desert, Zone 6), my experience has been that
moonflowers don't need any encouragement. The lady that we bought our
house from had planted moonflowers and they became quite invasive. It
took about 5 years for me to irradicate them, and even now after 15
years, I still occasionally see one pop up.
Assuming we are talking about the same variety, I'd advise caution. :)
