I'm so excited for you! Pirouette is one of the roses I ordered from Palatine a few weeks ago. It sounds like a perfect short climber and I'm looking forward to growing it.
You probably should plant Rainbow Niagara and Pink Enchantment in the back of a bed. They get very, very big. My Rainbow Niagara is easily 7-8 feet tall. Incidentaly, it might be a new name for the Tropical Sunrise that was being discussed recently in another thread in this forum. Pink Enchantment is the new name for Souvenir de Baden-Baden, and it also grows quite big. Not as tall as Rainbow Niagara, but still about 5 feet tall and 4-5 feet wide. Paradise is no slouch either. It's about 4-5 feet tall and 4 feet wide. The rest are smaller and probably won't grow above 3 feet.
You can look forward to some wonderful colors!
