My grandmother has about 5 large rose bushes. One white one, one pink one, one red one, and two yellow ones. During the spring of 2009 all of the rose bushes except the white one bloomed with a bright reddish-marroon colored roses. We have no idea why and wish someone knew why this happened but so far nobody knows... The white rosebush is the only one that blooms with the same white roses every year, the others all come back with the reddish-marroon colored roses. Sorry for the long post but i didnt really know how to word my thoughts. I hope you understood the post and thanks for looking!
