thank you Jennifer, I love first hand information.
do you think yours spreads from seed? or does it spread like rudbeckia or loosestrife, that will choke out everything by spreading roots?
i've watched this plant for years and it's stayed in its lane. is your experience different? we live on a street with houses on one side and a woods and field on the other... i've admired this plant for years, it's never made babies or spread in his yard, nor has it turned up with the weeds across the st. i'm pretty confident it's not choking you by runners, and only by seed( i'm not sure if that's a question or statement, but you're reply will help me decide. ) I live in a city environment and it's very possible Mr. Piece cuts his to the ground before the seeds mature? he maintains a pristine yard... it's a very Italian grandpa NYC where hedges are clipped at 1960 level square and the path is multi colored slate... he dead heads everything before it turns brown...
he likes a much more rigorously defined garden than my English county style, and he's way more disciplined than I, so i'm very interested in your input
