I am in the same boat. I have "Grand Finale" planted in the front yard. FULL
sun, watered regularly, fertilized up the ying yang, and what do I get? Ugly
white roses, that sometimes don't open, and plain look like junk. If the
rose doesn't start acting normally, it shall be shovel pruned!

I have JFK in the backyard, and that one doesn't perform well either.

It's the last time I buy white roses!
