Edmunds Roses lists Wild Blue Yonder as zone 5.

This is one of those love or hate colors. I bought it, and the plant is great, but the bloom color is not for me. I had the same reaction to 'Outta the Blue'. The color is just does not hit me. So, take that into consideration with some of these purple types out there now.

Another dead rose, even though there was quite a bit of this rose going into winter of 2013, and our average day was 24F, we had many days of -25F.

My camera makes this rose to be more cerise but the bloom is actually more grape colored. Soil pH is the reason for the differences we are seeing in the photos (aside from digital camera's fault), I didn't think my soil was that acid, but just about every "red" rose I have planted have all turned out to be a dark purple-raspberry color.

It does have the white eye as it ages, and it is fragrant, but I can't seem to smell most roses, so for me it seem like it's moderate in fragrance. It's about the strength of Rosenwunder, a polyantha planted nearby. And even though this is a modern rose, the blooms blend nicely with the older roses in the garden.

May 23, 2012: Of all the Carruth roses we have: Shockwave, Purple Splash, Scentimental, this one, "Wild Blue Yonder" is the healthiest; but even then, it will lose leaves to blackspot, and shuts down in very hot weather.
