that is, if it is a rose. I am not entirely certain, but if it is, its orange center looks very unique to me. does anyone know if this is indeed a rose? we inherited this bush when we purchased our home. this is the most blooms it has ever had so I had to share it with you. today is abc wednesday, and the letter is U. if you'd like, please go here to see more U representations. but most importantly, have a good wednesday!
