Rose Cornet and Mrs. R.G. Sharman-Crawford are two of the possible identifications which have been considered for the past 25+ years. I sent bud wood of Grandmother's Hat to The Netherlands last year in hopes someone over there who has access to both of these other roses would grow them all together and report how they differ or resemble each other. I hope someone can and will clear up this long-running mystery. I also included Larry Daniels, Tina Marie and Jeri Jennings' Striped Grandmother's Hat in case the solid, darker pink is a mutation and one of the lighter variations is the original form.
