It's so hard to pick a favorite... I've got a lot of old HT's and Floribundas that I'm quite fond of. Also many Austins are good performers (not all though). The only species I have is Rosa glauca, and it merrily seeds all over the place if I leave the hips on too long. I prefer roses with fragrance and disease resistance.. Some with high petal counts ball up, and some don't.. High on my favorite list would be 'Sombreuil', 'Shot Silk', 'Iceberg', 'Julia Child', & 'Festival Fanfare'.... 'St. Elisabeth of Hungary' was going gangbusters until the deer got in the garden.. I suspect it will be high on my list in coming years..
