The nemophila in the flower pot are fine (other than occasionally being sat upon by squirrels with Obsessive-Compulsive Disorder.) The two I transplanted out in the weed bed around the tree in the front yard are fine. The last lone straggler up against the foundation by the house? Well, it got mysteriously shorter over time as something nibbled it away, until the other morning it was just... gone.
This mysterious predator of nemophila obviously can't fly, climb, or jump to the flower pot, and won't trek across the front yard to the weed bed, only lurking in the shadow of the house. I blame the prolific little sow bugs.
