Lucy, how do those Austins perform for you? I've had mixed results with them, I think a lot don't like our heat and humidity, although most have a nice first flush of blooms.
I picked up a rose called 'Carefree Celebration' last week that is very similar in coloring to 'Tropicana'- that coral-orange color. Keeping my fingers crossed its as carefree as the name suggests!
