The "Carefree" series, Carefree delight, Carefree wonder, are good ones Also Shrub rose Knockout ( cherry red) is a great one! ( No spraying constant blooming!) Pretty Lady is a good one too. Alot of the modern shrub roses are easy care, well suited to landscaping! Lee

In zone 5, rugosas are great. Carefree, disease resistant, repeat blooming, and fragrant. Hansa is a great one and there are many others. Ask on the Antique Rose Forum for more zone 5 suggestions.

I think one of the major requirements in a landscape rose for a public area should be that it's not what the public perceives as a "rose", i.e., no high centered large bloom style roses. Those get cut, stolen, and dug up.
