Yes. Despite both the 69 and 77 roses being red; and the 69 flori possibly more likely to produce a mini-flora, versus the 77 hybrid tea. But the clincher for me is the perfume with the 77 hybrid tea 'Taxi' being a descendant of 'Fragrant Cloud'. I've changed the parentage from the 1969 'Taxi' to the 1977 'Taxi'. Thanks again Michael.
Overnight Scentsation has magnificently fragrant blooms that make great boutonnieres and is well worth growing, but it is not winter hardy. I lost four of my original five plants over two winters while they were lying down under thick snow cover (perhaps Zone 5 on the US scale). Now I bring mine in the house as a pot plant over winter.
As with most of my minis here in Central New York, mine dies back to the ground every year. This ordinarily wouldn't be a problem - most of them just pop right back up. O.S., however, has proven to be an absolute blackspot magnet for me - moreso than any rose I've ever grown, period. It almost completely defoliated last year. I'm amazed it survived the winter at all. It's a wonderful plant when it's healthy, and the fragrance really is on a par with my old damasks, but if it repeats this behavior this year, it's bound for the shovel.
