 I think it may be climate related.  Tho' why Brunnera doesn't seed
 for you, I don't know, as it likes a cool climate much better than a
 hot, sticky one - same for Alchemilla.

100 miles north in Columbus Ohio people do have brunnera reseeding.  Maybe 
Cincinnati falls into the hot, sticky category.  I know it does by July!  
BTW, the variegated brunnera planted three years ago is finally coming into 
its own and looks spectacular.  

  A number of the plants on my
 list seed madly into the gravel of the drive and parking area, but
 not into my beds and borders - or into paving cracks.  
===>Like it needs the heat generated by all the stones to germinate?  Who 
knows?  Sometimes the plants seem perverse.
 
 My Tovara filiformis 'Painter's Palette'  acted like it wasn't going
 to make it for about three years and last year, I started noticing
 some seedlings - some very remote from the parents.  
===>I think I'm going into my 4th year with it.  Time to jump back I hope.  
Yes, I think it can become rampant from what I've read about it.

 Nicotiana sylvestris... So, think you're climate is just too cold for it.  
===>You're probably right about this.  I'm still watching for seedlings 
around last year's planting, though, because winter was mild here this year.
 
 I betcha $$$ I know what your mystery weed is...bitter cress, AKA
 Cardamine hirsuta or C. Pensylvanica.  
===>That's it, Marge.  From the photos, though, it is a little hard to tell.  
The plant's parts are really so fine that it doesn't show up well, does it?  
It is truly obnoxious, but I think I would rather have it than chickweed, if 
anyone gives me a choice.
