Wildlife Spotting

Tall leafy plant, it's about 6 feet tall or more. It reminds me of lovage or celery, but I found the lovage my mom planted in her garden and this is different. My mother passed away before her garden started regrowing, so she isn't here to tell me what she planted and what she has growing. I know she was into herbs, but I don't recognize a lot of the things that are popping up throughout the garden!
