Name: Michele Roth N.E. Indiana - Zone 5b, and F (Zone 9b) I'm always on my way out the door..
So far, I have "tame" larkspur. It only seeds a few new ones each year....just right. I do, however, clip off the flower spikes and toss them in the trash before some of the seeds have a chance to drop.
Very nice, Janice! What "flavor" of pieris is that?
