I was amazed by all of the different colors in Gold Medal, Toni. I had just assumed it was a solid yellow rose until I saw it in all its glory (for sale at the local Rite-Aid drugstore, to my surprise).
I have Golden Showers and it doesn't match in any way but height. It's lighter yellow and the blooms don't have as many petals. Also, these blooms have staying power and the blooms on Golden Showers seem to shatter in just a few days.
Oldtimer's too orange and Golden Masterpiece has too many petals.
