On another gardening site, I once made a list of the 10 roses I'd always have to grow, even if I only had a tiny patio. They were:
Bill Warriner
Brass Band
Charisma
English Elegance
Helen Hayes
Night Time
Paradise
President Herbert Hoover
Pure Poetry
Smoky
I made the list back in 2006, so there are new roses that I could add to the list, but those were my favorites then and they're still irreplaceable to me.
