Hi Nick. Welcome to the Forums here, at NGA !
I've grown tobacco before. The seeds are very tiny & get sown on the surface. Use very clean hands & sow thinly, on top of microwaved seed start mix ( allow to cool off first,) before sowing & keep humid. & warm, but shaded until it gets a little bigger & gradually expose to more direct sun.
At this time of year, it may need to be done in the shade. A neighbor I knew, used to grow it in N. Carolina too, by the hundreds of acres.... I had asked, what kind I had & the elderly gentleman guessed & sure enough, he named what I had grown from seeds, correctly. Maybe #86 ?
The flower stalk, is supposed to be removed ( unless you want to save seeds.) As nicotine is rather toxic, & can be absorbed through your skin, take precaution. I was told by one woman that did that 'flower top removal" as summer time work, & she'd actually become poisoned from working in a field "topping them" & she had started to take on a greenish appearance, shortly after starting the job !
While Marshmallow, grew wild, at the edge of the yard, where it was the edge of the marsh ( as the name implies) but not close to the ( salty/brackish) Creek, as the soil tended to stay moist, almost like that consistency of damp mud.
Not sure about the others, though
