Thanks Salix. There is no mention of moss either in the Patent or the refs. We've deleted that misleading sentence and we thank you for your correction.
This is a really beautiful miniature rose. Without pruning it grew way over 36 inches, which I've read isn't rare, but it should be cut back because growing that tall reduces bloom. I found it always laden with red and white striped flowers. I never had a problem with it, not even black spot, until I moved it from a full sun (8 hours) to a partial sun (5 hours) location, I then got one good flush and then it just died. My fault, I wish I'd left well enough alone.
