last time I posted a phots. like 2 weeks or so ago. they thought it was campanula. Or a weed. I don;t think its mint. there was jsut a little of it laast year. Never bloomed that I remember. Its driving me nuts !
Think hard, Mings, could it have had a little yellow flower, about a half inch across? Is the stem wiry? If so, you might have straggler daisy, and you will never get rid of it, but you must still battle it daily. It will take over! I put roundup on some, and it didn't even blink, just took over the spot where the crab grass died.
Hi, It looks like my ladybells-Adenaphora confusa--tall spikes with medium purple bells--get about 24" high here in WI-grows in sun/pt shade; I have never had problem with disease or insects, give it no care at all-it does tend to spread a bit. I like it for the ease of care,as a cut flower and that, when the spikes are done blooming, I just pull them off and get a shorter second bloom.
