Austins grow well here too. So do Kordes roses. I've often said that I'd grow nothing but Austins and Kordes Fairy Tale roses if I ever had to move to a place with a smaller garden.
Virtually every rose in my garden gets black spot. The Buck roses are the worst in that respect. I kept a log of BS-free roses one year and ultimately had to remove every rose from the list as the year went on, with the exception of 'Playboy,' which never had a single spot. Ping Lim's roses are also virtually immune to black spot in my garden. exhibiting only a few mild symptoms during the year.
