White Cloud Climbing Rose Turned Red—Rootstock or Sport?

12-year-old ‘White Cloud’ now red: likely Dr. Huey rootstock takeover (winter kill). Check: if all blooms red = rootstock. If only a few red = sport (genetic mutation). Dr. Huey photo: TheOldRosarian.com.

If rootstock, replace with hardier climber or own-root white.
