Would it be possible for someone to assist me in identifying the two different species of berberis that I have on my property, via pictures? I have both thunbergii and vulgaris (I assume that's what I have, because I have 2 thoroughly different plants); I hope to get rid of the former but I need to know which is which. I have checked michiganflora, but I would feel better if someone with more expertise could make the call. If pictures would help, do you need close-ups of the inflorescence, or what? Please let me know what you need from me. Thank you
