Q.2 colour rose
Could you please explain to me why my rose has grown one half white and one half burgundy. Bush is 3 years old.
Many thanks Lynn

It sounds like one of two things has happened. The rosebush has done what is called forming a Sport. A new rosebush put forth by the same rose. Or perhaps part of the grafting of the rose reverted to another portion of the graft such as having a burgundy and white iceberg rose. Or perhaps one color of rosebush grew in that location originally, someone thought it had died so planted another but did not get all of the root system from the first, thus you now have both growing up from what appears to be the same bush.
