I didn't see much phlox either! My dh does the mowing so no telling if he mowed any down even though he knows better!!!
Thank you, Pod, that would be nice if you just keep an eye out for seeds. I've read conversations over the years about gardeners trying to help the plant pollinate and/or find seeds so I know seed is not always found. I do know that Sampson's Snakeroot will put out seeds and I'll definitely check when to look for them. I like to collect the seeds for others and will save some for you.
