Ketchup and Mustard is an inferior rose, in my opinion. The two that I grow have failed to thrive, and friends in my area have reported the same issues. The plant had wonderful roots and strong canes, but it just didn't grow.
Both of mine put out just 2 or 3 nice blooms all season. The only really good bloom it ever had is the one you see in my avatar! Mine are planted in a prime spot. So disappointing.
