I am writing because I have a salmon-colored perennial in my garden that I probably planted (but I'm fairly certain must have been a substitution from an online order, which is why I don't know what it is--I unfortunately didn't keep the paperwork.) It's taking over my garden, and am immensely curious to know what it is so I can research it. Please advise if anyone can help me identify this. Please note the two pictures of the foliage were taken after I trimmed off the tall flower stems once the blooms were finished for the season. Thank you! (if it helps, I'm located in New York City, which I believe is Zone 6?)
