Comments

Well done! You provided several pieces of photo evidence to support your claim. Leaves, flowers, stem are all great ways to identify plants.and you presented a strong case. Especially love the square stem photo.

It looks like your leaves have had something eating at them. If Lythrum salicaria is not native, do you know what might be eating the leaves?

Great job. Keep up the good work looking finding and documenting.
