It seems that the plant that grows at the Heritage may be Portland from Glendora.

The rose at the Heritage is not the same rose growing at Brooklyn Botanical Gardens. The one at the Heritage reblooms. The rose offered by Vintage and Rogue Valley is described as having white petal bases and no rebloom, so is probably not the rose shown on my photos. Also, the first reference quoted in the reference section here describes the damask, not the moss.
