Q: I am interested in the disease-resistant qualities exhibited by roses developed by Bill Radler, the originator of Knock Out(tm) roses. Which climber would you recommend?

A: I found online three climbing roses with links to Mr. Radler: Morning Magic(tm), ‘Winners Circle’, ‘Ramblin Red’ and ‘Cancan’. I haven’t had experience with any of them but Radler is well-known for his breeding ability.
