"simy1" expounded:

I collected moonflower seeds from an acquaintance's garden last year,
and they produced several plants in my own garden. He has now moved
away, and I recall that he had them year after year. But I read that
moonflower is an annual in Michigan, so I suspect his plants were dying
but reseeding. Mine have not yet produced seeds. Do you think they will
come up next year? Also, I planted them a bit too thickly. If they will
survive, anything I need to know before I move a few in a month?

What are you calling Moonflower? Datura? If so, it is marginally
hardy here. The way you tell that it's a returnee is there are
multiple stems coming out of the ground, very late in the spring. The
seedlings come up with single stems (of course). Usually I'll see
them come back if I've had a fair amount of snowcover over the winter
and the spring isn't interrupted with lots of hard frosts (doesn't
happen often but I did get one come back this spring).
