Not sure what this is, hoping someone can enlighten me. The one with the stalks I believe is the same but mature plant, as it has same leaves at the bottom. It's growing in my wildflower bed, along with literally loads of oxeye daisies, and both seem to be spreading everywhere at an alarming rate! I'd rather some prettier insect attracting wildflowers, but both of these seem to be smothering everything else, are they any use to bees, insects etc? I don't particularly want them to appear again next season, do I just pull them now. I plan to revamp the area, it's about 3x1 metre, and lay a wildflower seed roll there. Thanks for any info/advice.
