I live near Chicago (zone 5), and I put in Palmengarten Frankfurt three years ago. It has proved hardy without winter protection, and is 99% blackspot free, despite an overhead automatic watering system and only about five hours of full sun a day. It was somewhat slow to get established but is now quite beautiful. It is one of my last roses to bloom, beginning at the end of June, but its combination of good looks and disease resistance make up for the shorter season. I am delighted to have it.
Hi, thanks for your review of Palmengarten Frankfurt. I was wondering if you thought this would make a decent container plant? I understand this grows only 2-3' tall but what's been your experience? Thanks
the height is indeed only 2-3 ft., but it takes awhile to establish properly -- two or three years. So unless you live in a climate where it can winter over, I'm not sure it will reach its full glory as a container plant. Good luck!
